The Three Sentence Rule
Variations of the Three Sentence Rule have been around for a long time. The differences are multiplicative but the base rule is a useful and often necessary tool to teach concision to the wordy.
Say what you need to say in THREE sentences, or less.
Anyone who has been through flight school learns how to be concise on the radio. Who are you? Where are you? What do you want? That happens to be three sentences. “Palo Alto Tower, Cessna 15957X; 5 miles southwest of SLAC with information Echo; request landing.” The need to be precise, accurate and speedy is a requirement at a tower as busy as Palo Alto tower. Controllers have no patience because there are 12 other aircraft waiting to communicate.
As technologists, we are generally rewarded for producing details, the more the better. Engineers have to be obsessed with substance; their work is about precision and there are no shortcuts when it comes to building complex tools. It wouldn’t make any sense to try and distill how Cassandra compares to a relational database, in three sentences, in a room filled with colleagues, at a meet-up.
But what if our CEO asks us about Cassandra? How can we possibly explain to someone who is just a wee bit tech-illiterate the differences between two very different data stores? Moreover, why on earth would we try and distill that down to three sentences?? Let’s start at the beginning… before there were databases there were Hollerith Cards…
Lack of brevity is a death sentence to any technologist who finds themselves interacting with non-technologists on a regular basis. We see this as a common anti-pattern for CTOs; some never learn the difference between a novel, a paragraph, or sentence and why each has utility.
The controller in the tower could care less about why we’re in an airplane today, that we’re stopping at the restaurant for the traditional $100 hamburger and that we need to be home for dinner tonight:
- Who are you?
- Where are you?
- What do you want?
- Cassandra is a new database technology.
- It’s very different than what we use today.
- It will lower costs in the next 12 months.
That is the CEO-version of Cassandra in three sentences. “What is it called, why should I remember it, what does it do for me?”
At AKF Partners, we believe that technology executives need to start practicing a version of the three sentence rule as soon as they transition into their first leadership role. Specialists in Operations roles have an advantage because of the daily chaos and need for ongoing communications: “Customer sign-in unavailable for 15 minutes; 100% of our customers are impacted for 15 minutes; we are restarting the service for 100% operations in 10 minutes—update in 20 minutes.”
- What happened?
- What is the impact?
- When is it going to be fixed?
There’s a practical reason for such precision: most CEOs are consuming information on tiny screens, sometimes over really bad internet (Detroit Airport) at 2 in the morning, and news also just arrived about a sales crisis in Europe, there’s a supply-chain issue in India, and the Wall Street Journal is doing a feature about the product that’s going live next week. If we mentioned Hollerith, or even thought about it for a second, we’re Exploring Alternative Employment. If they have a moment to breath, they can ask for more detail. Or maybe next week.
Sometimes we’re required to communicate when there’s no answer. Try this:
- Impact update,
- Standard procedures failed, assembled SWAT,
- Updates every 15 minutes until resolution.
An equally important rule for executives is the “No Surprise Rule” (stay tuned) and zero sentences are as fatal as 4 sentences at the wrong time. Keeping a CEO waiting for 2 hours until root cause is determined is stupid.
The final place to consider the Three Sentence Rule is the boardroom itself. Most boards members are not going to read through the 200 page board deck, and our ten minutes to discuss the Cassandra project is unlikely to resonate with most of the attendees. Up and coming executives understand the need for absolute precision. Steve Jobs could do it with a single slide:
Three sentences, if you count the background gradient as a sentence.
For the Board:
- We’re introducing new technology next fiscal year.
- It’s called Cassandra.
- A year from now I will demonstrate how it increased EBITDBA by $2M.
- Anything can be explained in 3 sentences
- Even concepts so fantastic they seem magical
- If you don’t believe me, Books in 3 Sentences
At AKF Partners, we can help with mentoring, coaching and leadership training.

More and more companies are waking up from the 20th century, realizing that their on-premise, packaged, waterfall paradigms no longer play in today’s SaaS, agile world. SaaS (Software as a Service) has taken over, and for good reason. Companies (and investors) long for the higher valuation and increased margins that SaaS’ economies of scale provide. Many of these same companies realize that in order to fully benefit from a SaaS model, they need to release far more frequently, enhancing their products through frequent iterative cycles rather than massive upgrades occurring only 4 times a year. So, they not only perform a ‘lift and shift’ into the cloud, they also move to an Agile PDLC. Customers, tired of incurring on-premise IT costs and risks, are also pushing their software vendors towards SaaS.
SaaS Migration is About More Than Just Technology – It is An Organization Reboot
But, what many of the companies migrating to SaaS don’t realize is that migrating to SaaS is not just a technology exercise. Successful SaaS migrations require a ‘reboot’ of the entire company. Certainly, the technology organization will be most affected, but almost every department in a company will need to change. Sales teams need to pitch the product differently, selling a leased service vs. a purchased product, and must learn to address customers’ typical concerns around security. The role of professional services teams in SaaS drastically changes, and in most cases, shrinks. Customer support personnel should have far greater insight into reported problems. Product management in a SaaS world requires small, nimble enhancements vs. massive, ‘big-bang’ upgrades. Your marketing organization will potentially need to target a different type of customer for your initial SaaS releases - leveraging the Technology Adoption Lifecycle to identify early adopters of your product in order to inform a small initial release (Minimum Viable Product).
It is important to recognize the risks that will shift from your customers to you. In an on-premise (“on-prem”) product, your customer carries the burden of capacity planning, security, availability, disaster recovery. SaaS companies sell a service (we like to say an outcome), not just a bundle of software. That service represents a shift of the risks once held by a customer to the company provisioning the service. In most cases, understanding and properly addressing these risks are new undertakings for the company in question and not something for which they have the proper mindset or skills to be successful.
This company-wide reboot can certainly be a daunting challenge, but if approached carefully and honestly, addressing key questions up front, communicating, educating, and transparently addressing likely organizational and personnel changes along the way, it is an accomplishment that transforms, even reignites, a company.
This is the first in a series of articles that captures AKF’s observations and first-hand experiences in guiding companies through this process.
Don’t treat this as a simple rewrite of your existing product –
Answer these questions first…
Any company about to launch into a SaaS migration should first take a long, hard look at their current product, determining what out of the legacy product is not worth carrying forward. Is all of that existing functionality really being used, and still relevant? Prior to any move towards SaaS, the following questions and issues need to be addressed:
Customization or Configuration?
SaaS efficiencies come from many angles, but certainly one of those is having a single codebase for all customers. If your product today is highly customized, where code has been written and is in use for specific customers, you’ve got a tough question to address. Most product variances can likely be handled through configuration, a data-driven mechanism that enables/disables or otherwise shapes functionality for each customer. No customer-specific code from the legacy product should be carried forward unless it is expected to be used by multiple clients. Note that this shift has implications on how a sales force promotes the product (they can no longer promise to build whatever a potential customer wants, but must sell the current, existing functionality) as well as professional services (no customizations means less work for them).
Many customers, even those who accept the improved security posture a cloud-hosted product provides over their own on-premise infrastructure, absolutely freak when they hear that their data will coexist with other customers’ data in a single multi-tenant instance, no matter what access management mechanisms exist. Multi-tenancy is another key to achieving economies of scale that bring greater SaaS efficiencies. Don’t let go of it easily, but if you must, price extra for it.
Who Owns the Data?
Many products focus only on the transactional set of functionality, leaving the analytics side to their customers. In an on-premise scenario, where the data resides in the customers’ facilities, ownership of the data is clear. Customers are free to slice & dice the data as they please. When that data is hosted, particularly in a multi-tenant scenario where multiple customers’ data lives in the same database, direct customer access presents significant challenges. Beyond the obvious related security issues is the need to keep your customers abreast of the more frequent updates that occur with SaaS product iterations. The decision is whether you replicate customer data into read-only instances, provide bulk export into their own hosted databases, or build analytics into your product?
All of these have costs - ensure you’re passing those on to your customers who need this functionality.
May I Upgrade Now?
Today, do your customers require permission for you to upgrade their installation? You’ll need to change that behavior to realize another SaaS efficiency - supporting of as few versions as possible. Ideally, you’ll typically only support a single version (other than during deployment). If your customers need to ‘bless’ a release before migrating on to it, you’re doing it wrong. Your releases should be small, incremental enhancements, potentially even reaching continuous deployment. Therefore, the changes should be far easier to accept and learn than the prior big-bang, huge upgrades of the past. If absolutely necessary, create a sandbox for customers to access new releases, but be prepared to deal with the potentially unwanted, non-representative feedback from the select few who try it out in that sandbox.
Wait? Who Are We Targeting?
All of the questions above lead to this fundamental issue: Are tomorrow’s SaaS customers the same as today’s? The answer? Not necessarily. First, in order to migrate existing customers on to your bright, shiny new SaaS platform, you’ll need to have functional parity with the legacy product. Reaching that parity will take significant effort and lead to a big-bang approach. Instead, pick a subset or an MVP of existing functionality, and find new customers who will be satisfied with that. Then, after proving out the SaaS architecture and related processes, gradually migrate more and more functionality, and once functional parity is close, move existing customers on to your SaaS platform.
To find those new customers interested in placing their bets on your initial SaaS MVP, you’ll need to shift your current focus on the right side of the Technology Adoption Lifecycle (TALC) to the left - from your current ‘Late Majority’ or ‘Laggards’ to ‘Early Adopters’ or ‘Early Majority’. Ideally, those customers on the left side of the TALC will be slightly more forgiving of the ‘learnings’ you’ll face along the way, as well as prove to be far more valuable partners with you as you further enhance your MVP.
The key is to think out of the existing box your customers are in, to reset your TALC targeting and to consider a new breed of customer, one that doesn’t need all that you’ve built, is willing to be an early adopter, and will be a cooperative partner throughout the process.
Our next article on SaaS migration will touch on organizational approaches, particularly during the build-out of the SaaS product, and the paradigm shifts your product and engineering teams need to embrace in order to be successful.
AKF has led many companies on their journey to SaaS, often getting called in as that journey has been derailed. We’ve seen the many potholes and pitfalls and have learned how to avoid them. Let us help you move your product into the 21st century. See our SaaS Migration service

The Law that Almost Wasn’t
Conway’s law had a rather precarious beginning. Harvard Business Review rejected Conway’s thesis, buried as it was in the 43d paragraph of a 45-paragraph paper, on the grounds that he had not proven it.
But Mel had a PhD in Mathematics (from Case Western Reserve University – Go Spartans!), and like most PhDs he was accustomed to journal rejections. Mel resubmitted the paper to Datamation, a well-respected IT journal of the time, and his paper “How Do Committees Invent” was published in 1968.
It wasn’t until 1975, however, that the moniker “Conway’s Law” came to be. Fred Brooks both coined the term and popularized Conway’s thesis in his first edition of the Mythical Man Month. It has since been one of the most widely cited, important but nevertheless incorrectly understood and applied notions in the domain of product development.
Cliff’s Notes to “How Do Committees Invent” (the article in which the law resides)
Conway’s thesis, in his words:
… organizations which design systems (in the broad sense used here) are constrained to produce designs which are copies of the communication structures of these organizations.
Conway calls this self-similarity between organizations and designs homomorphism. Preamble to the thesis helps explain the breadth and depth:
… the very act of organizing a design team means that certain design decisions have already been made, explicitly or otherwise
Every time a delegation is made … the class of design alternatives which can be effectively pursued is also narrowed.
Because the design which occurs first is almost never the best possible, the prevailing system concept may need to change. Therefore, flexibility of organization is important to effective design.
Specifically, each individual must have at most one superior and at most approximately seven subordinates
Examples. A contract research organization had eight people who were to produce a COBOL and an ALGOL compiler. After some initial estimates of difficulty and time, five people were assigned to the COBOL job and three to the ALGOL job. The resulting COBOL compiler ran in five phases, the ALG0L compiler ran in three.
There are 4 very important points, and one very good example, in the quotes above:
1) Organizations and design/architecture and intrinsically linked. The organization affects and constrains the architecture - the opposite is not true.
2) Depth of an organization negatively effects design flexibility. The deeper the hierarchy of an organization, the less flexible (or alternatively more constrained) the resulting architecture.
3) We will make mistakes and must organize to quickly fix these.
4) Team size should always be small – which also has an implication to the size of the solution part a team can own (think Amazon’s re-branding of this point of the “2 Pizza Team” (author’s side note – read Scalability Rules for how this came about).
Important corollaries to Conway’s law suggest that if either an organization or a design change, without a corresponding change to the other, the product will be at risk.
Common Failures in Application of Conway’s Law and How to Fix Them
There are five very common failures in organization and architecture within our clients, the first four of which relate directly to Conway’s points above:
1) Organizations and architectures designed separately. Given the homomorphism that Conway describes, you simply CANNOT do this.
2) Deep, hierarchical organizations. Again – this will constrain design.
3) Lack of flexibility. Companies tend to plan for success. Instead, assume failure, learning, and adaptation (think “discovery” and “Agile” instead of “requirements” and “Waterfall”).
4) Large teams. Forget about these. Small teams, each owning a service or services that the team can support in isolation.
There is a fifth violation that is harder to see in Conway’s paper. Too often, our clients don’t build properly experienced teams around the solutions they deploy. Success in low-overhead organizations requires that teams be cross functional. Whatever a team needs to be successful should be within that team. If you deploy on your own hardware, you should have hardware experience. If you need DBA talent, the team should have direct access to that talent. QA folks should be embedded within the team, etc. Product managers or owners should also be embedded in the team. This creates our fifth failure:
5) Functional teams. Don’t build teams around “a skill” – build them around the breadth of skills necessary to accomplish the task handed to the team.
Conway’s Parting Shot and Food for Thought
Noodle on this: Conway identified a problem early in the life of a new domain. Yet what was true in Conway’s time as a contributor to the art is still true today, over 50 years after his first attempt to forewarn us:
Probably the greatest single common factor behind many poorly designed systems now in existence has been the availability of a design organization in need of work.

In 1965, psychologist Bruce Tuckman published his theory of group dynamics. This theory describes the stages (or phases) through which a team progresses enroute to optimal productivity. While generally useful for any organization, and prescriptive as to what leaders should do when to boost performance, it has profound impacts to Agile development practices and how we build organizations around these Agile practices.
The first stage is forming. This is where the team first comes together. Here, the individuals are trying to get to know each other. They tend to be polite and cordial, but they do not fully trust each other.
In this stage, the team productivity and team conflict are low. The team spends time agreeing to what the team is supposed to do. This lack of agreement of the team’s purpose can cause members to miss goals because they are individually targeting different things. Team members rely on patterned behavior and look to the team leader for guidance and direction. The team members want to be accepted by the group. Cautious behavior on the part of the team starts to depress overall team outcomes. Good leadership, emphasizing goals and outcomes is important to set the stage for future team behaviors and outcomes.
Once the team’s goals are clear, they move into the next stage, storming. Here, the team starts to develop a plan to achieve the goal and defines what to do and who does it. Friction starts to occur as members propose different ideas. Trust within the team remains low and affective conflict rises as people vie for control. Cliques can form. Productivity drops even lower than in the first stage.
Once the team agrees on the plan and the roles and responsibilities, it can move to the next stage. Without agreement, the team can get stuck. Symptoms include poor coordination, people doing the wrong things and missing deadlines, to name a few. Good leadership here focuses on fast affective conflict resolution, and serves to help reinforce team goals and outcomes in order to quickly move to more productive phases.
Once team members agree to the plan and understand their roles, they enter the norming phase. Affective conflict goes down, cognitive (beneficial) conflict and trust increase. The team focuses on how to get things done and productivity begins to increase. The team develops “norms” about how to work together and collaborate. A lack of these norms can cause issues such as low quality and missed deadlines.
Leadership within the team becomes clear and cliques dissolve. Members begin to identify with one another and the level of trust in their personal relationships contributes to the development of group cohesion. The team begins to experience a sense of group belonging and a feeling of relief from resolving interpersonal conflicts. Team identity starts to take hold and innovation and creativity within the team increases. The members feel an openness and cohesion on both a personal and task level. They feel good about being part of the team.
The final stage, preforming, is not achieved by all teams. This stage is marked by an interdependence in personal relations and problem solving within the realm of the team’s tasks. Team members share a common goal, understand the plan to achieve it, know their roles and how to work together. The team is firing on all cylinders. At this point, the team is highly productive and collaborates well. They are trusting of each other and “have each other’s back.” Healthy conflict is encouraged. There is unity: group identity is complete, group morale is high, and group loyalty is intense.
Not all teams get to this phase. They can get stuck in a previous phase or slide back into them from a higher phase. Leadership that focuses on affective conflict resolution, team identity creation, a compelling vision and goals to achieve that vision is critical to reaching the Performing phase. It is usually not easy for teams to quickly progress through these stages, and it often takes 6 months or more for a team to reach the Performing phase.
Impact to Agile Development
We often see companies make the mistake of coalescing teams around initiatives. Sometimes called “virtual teams” or “matrixed teams”, these teams suffer the underperforming phases of Tuckman’s curve repeatedly, especially when these initiatives are of durations shorter than 6 months. But even with durations of a year, six months of that time is spent getting the team to an optimum level of performance.
Tuckman’s analysis indicates that teams should be together for no less than a year (giving a 6 month return on a 6-month investment) and ideally for about 3 years. The upper limit being informed by the research on group think and its implications to creativity, performance and innovation within teams. Teams then should become semi-permanent and we should seek to move work to teams rather than form teams around work. To be successful here, we need multi-disciplinary teams capable of handling all the work they may get assigned. Further, the team needs to be familiar and “own” the outcomes associated with the solution (or architectural components) with which they work. More on that in future articles discussing Conway’s Law and Empathy Groups.
AKF Partners helps companies understand and apply the extant theory around organizational development in order to turbo-charge engineering performance.

We have a saying in AKF Partners that “an incident is a terrible thing to waste”. When things go poorly in a firm, stakeholders (shareholders, partners, employees) pay a price. Having already paid a price, the firm must maximize the learning opportunity the incident presents. Google wasted such a learning opportunity by failing to capitalize on an incredible teaching moment with the termination of James Damore (the author of the sometimes called “Anti-Diversity Manifesto”). While Google seems to have “done the right thing” by firing Damore, it is unclear that they “did it for the right reason”. The “right reason” here is that diversity is valuable to a company because it increases innovation and in so doing increases the probability of success. Further, diversity is hard to achieve, takes great effort and can easily be derailed with very little effort. Companies simply cannot allow employees to work at odds with incredibly valuable diversity initiatives.
Diversity Drives Innovation and Success
My doctoral dissertation journey introduced me to diversity and its beneficial effects on innovation, time to market, and success within technology product firms. Put simply, teams that are intentionally organized to highlight both inherent (traits with which we are born) and acquired (traits we gain from experience) diversity achieve higher levels of innovation. Research published in the Harvard Business Review confirms this, indicating that diverse teams out innovate and out-perform other teams. Diverse teams are more likely to understand the broad base of needs of the market and clients they support. Companies with very diverse management teams are 35% more likely to have financial returns above the mean for their industry. Firms with women on their board on average have a higher ROE and net income than those that do not.
Differences in perspective and skills are things we should all strive to have in our teams. As we point out in The Art of Scalability, these differences increase beneficial cognitive conflict. Increases in cognitive conflict opens a range of strategic possibilities that in turn engender higher levels of success for the firm.
We have for too long allowed the struggle for diversity to be waged on the battleground of “fairness”. The problem with “fair” is that what is “fair’ to one person may seem inherently unfair to another. “Fair” is subjective and “fair” is too often political. “Success” on the other hand is objective and easily measured. Let’s move this fight to where it belongs and embrace diversity because it drives innovation and success. After all, anyone who can’t get behind winning, doesn’t deserve to be on a winning team.
Achieving Diversity is Hard
While the value of diversity is high, the cost to achieve it is also unfortunately high – especially within software teams. As my colleague Robin McGlothin recently wrote, the percentage of computer science degrees awarded to women over the last 25 years is declining. Most other minorities are similarly underrepresented in the field relative to their corresponding representation in the US population.
As in any market with high demand and low supply, companies need to find innovative ways to attract, grow and retain talent. These activities may include special mentoring programs, training programs, or scholarships at local universities meant to attract the group in question. These approaches may seem “unfair” to some, but they are in truth capitalism at its best - the application of market forces to solve a supply and demand problem. When a skill or trait is under high demand and short supply, the cost for that skill goes up. The extra activities above are nothing more than an increased cost to attract and retain the skills we value.
Companies desiring to achieve success in innovation through diversity MUST approach it in a steely, single-minded fashion. Any dissent as it relates to outcomes detracts from the probability of success. How many people with diverse backgrounds will leave or have left Google because of Damore’s missive? How many candidates won’t accept offers? Losing even one great candidate is an unacceptable additional cost given the already high cost to achieve success.
The Bottom Line
Structuring organizations and building cultures that tap the power of inherent and acquired diversity pays huge dividends for firms in terms of innovation, time to market, ROE and net income. While the rewards are high, the cost to achieve these benefits are also high. Success requires a steely, single-minded pursuit of diversity excellence.
The successful company will allow no dissent on this topic, as dissent makes the firm less attractive to the ideal candidate. Given a constrained supply under high demand, the candidate can and should go to the most welcoming environment available.
Put simply, Google did the right thing in firing Damore. But they failed to fully capitalize on the unfortunate event. The right answer, when asked about the reason for firing, would look something like this: “We recognize that diversity in experiences, background, gender and race drives higher levels of innovation and greater levels of success. Our culture will not tolerate employees who are not aligned with creating stakeholder value.”

We all suffer from various cognitive biases, those mental filters or lenses that alter or warp the reality around us. With the election of 2016, one particular bias has gained widespread attention - the Dunning-Kruger Effect. Defined in wikipedia as:
“...a cognitive bias, wherein persons of low ability suffer from illusory superiority when they mistakenly assess their cognitive ability as greater than it is.”
(If you’ve ever wondered about the behind-the-scenes process of creating Wikipedia content, look at this entertaining discussion.)
In 1999, while a professor at Cornell, David Dunning joined Justin Kruger to co-author a paper titled “Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments”, based on studies indicating that people who are incompetent in an area are typically too incompetent to know they are incompetent. Or, simply put, we are often in a position where we don’t know what we don’t know, and therefore cannot judge our level of expertise in a particular area.
This effect or bias, is also known as the ‘Lake Wobegon effect’, or ‘illusory superiority’, and is closely tied to the Peter Principle. Donald Rumsfeld put it this way:
There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don’t know we don’t know. And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones.
And in John Cleese’s words, stupid people do not have the capability to realize how stupid they are.
The story of how Dunning came to posit the D-K Effect is an amusing one. He read about an unusual bank robbery that occurred in Pittsburgh. What was unusual was that the robber, McArthur Wheeler, made absolutely no effort to disguise himself, and in fact, looked and smiled directly into the security cameras. Yet, he was surprised to quickly be arrested, telling authorities “...but I used the juice!”.
Wheeler told the police that they couldn’t arrest him based on the security videos, as wearing lemon juice, he was of course invisible. He had been told coating your face with lemon juice makes you invisible to cameras, perhaps similar to using lemon juice for invisible ink. Wheeler had even gone as far as to test the theory by taking a Polaroid picture of himself after coating his face with the lemon juice, and sure enough, his face didn’t appear in the print. The police never were able to explain this, but likely Wheeler was as incompetent at photography as he was at burglary. Clearly, Wheeler was too incompetent at burglary to know he was incompetent.
So, does Dunning-Kruger exist in the technology world? Absolutely…
Just as a typical driver believes their driving skills are Formula 1 worthy, until they’re on a track getting blown past by an inferior car driven by someone who has far better braking and cornering skills, we all tend to underestimate what is possible. We live in our own bubbles and are comparing our abilities only against those who also reside in our bubbles. Therefore, we don’t know what we don’t know - we don’t know there are far better drivers outside our bubbles.
You may think your organization is at the peak of efficiency, until you bring someone in from a Google, Facebook, Amazon, etc. who reveals what the true peak really can be - what fully Agile processes and cultures can do to reduce time to market, how effective SREs and DevOps can be, how to remain innovative, what continuous delivery can do to, etc.
AKF firmly believes in “Experiential Diversity” to cross-pollinate teams, injecting new DNA into a company or bubble that was grown in a different bubble. We see numerous companies with very static personnel, where the average employee tenure is over 15 years. There have been tremendous changes in the technology world in 15 years, and while reading a book or attending a conference on new processes brings some exposure to the latest and greatest, it isn’t enough. It is incredibly important to continually bring new blood into an organization, and to purposely tap into that diversity of processes, technologies, organizational structures that comes with the new blood.
Other techniques to mitigate the effect of D-K in technology, of eliminating our personal and organizational biases include:
- 360 degree reviews - Dunning himself has said “The road to self-insight runs through other people”. What better way to get feedback than from periodic 360 degree reviews?
- Code reviews - The likelihood that some percentage of your developers suffer from D-K means that you’re dependent upon code reviews to flush out their incompetence. Just make sure you’re not pairing up two D-K developers to perform the review!
- Planning Poker - requiring, in true Agile fashion, a team to estimate a task or project reduces the chance of that D-K estimate from torpedoing your development planning.
- Soliciting advice - the increasing utilization of open source software means there isn’t a vendor, with hopefully solid expertise, to turn to for advice. Instead of solely relying upon your own developer who only knows how to spell say Cassandra, leverage the appropriate OSS community. Just beware that you might not know whether that solicited advice is good advice.
- Proper interviewing - Ensure your interviewing process can weed out “confident idiots”. Consider planting bogus questions to gauge a candidate’s reactions, like Jimmy Kimmel’s “Lie Witness News”. At a minimum, require team interviewing and consensus for new candidates.
In short, Dunning-Kruger is as rampant within the Technology sector as it is anywhere else, if not even more so. Expect it to be present in your organization, and guard against it. Look at it within yourself as well. Who amongst us hasn’t experienced the shock of discovering we’ve failed a test that we actually thought we’d aced? We all have suffered at one time or another from the Dunning-Kruger effect.

We hear every day that more and more jobs are disappearing, yet the technology job sector cannot keep up with the unprecedented demand. So why are women falling behind in this growing career track?
When we look at the percentage of STEM bachelor’s degrees awarded to female students for the last two decades, based on NSF statistics, we find there are no gender difference in the bio sciences, the social sciences, or mathematics, and not much of a difference in the physical sciences. Great news for women scientists. The only STEM fields in which men genuinely outnumber women are computer science and engineering. What? Why the stagnant numbers in computer science?
At the PhD. level, women have clearly achieved equity in the bio sciences and social sciences, are nearly there (40 percent) in mathematics and the physical sciences, and are “over-represented” in psychology (78 percent). More good news. Again, the only fields in which men greatly outnumber women are computer science and engineering. Why no growth?
As I started my research for this blog post, I was pleasantly surprised to find women scientist representation growing in almost all aspects of STEM. And at the same time, disheartened to find my major, computer sciences, is stagnate in growth for women over the past two decades.
What’s different in the computer science & engineering aspects of STEM that seem to hold women back? There are many conflicting reports on how our environment and upbringing are sublimely programming women away from engineering and mathematics. We were told from an early age, math and science are for boys.
My mother was a pioneer and a strong female leader. She holds a PHD in Biochemistry, served as President for Academic Affairs and Provost at Salem International University. She demanded her daughters rise to any challenge and deliver to the best of our abilities. Never once did I doubt I had amazing talents and just needed to get busy using them. So, is it nature or nurture that helped me stay with STEM? Maybe a little of both.
I saw an article recently in the WSJ on Salesforce.com, where CEO Mark Benioff, is focused on ensuring women are represented fairly at every level in his company. Taking proactive steps like SFDC.com, to open doors for women, rings truer to me then the “poor little girl” theories on how to increase female participation in computer science and engineering.
The cloud-computing giant is two years into a companywide “women’s surge” in which managers must consider women when filling open positions at every level. They are also examining salaries for every role in the company to ensure women and men are paid equally. And finally, ensuring that women make up at least 30% of attendees at management summits or onstage roles at keynote presentations.
With some nurturing at home during early years of development and progress in the corporate landscape leveling the playing field, I believe we are finally set to see an upward trajectory for the last two laggard categories in STEM.
Future women engineers can see a world where their hard work and discipline will pay off, a road-map to success if you will. We no longer need to break through the old stereotypes, running faster and jumping higher to be considered half as good as our male counterparts. Instead, there will be fair and equal opportunity for career advancement for women engineers and computer scientists.
I would submit some of the best technology leaders today are women. My personal experience afforded me the opportunity to work with several top female technology executives. One of the best leaders I worked for is a power house that broke all the stereotypes, and worked circles around her male counterparts. As I look back and try to understand what propelled these successful women, they all possess some classic traits that are needed in any leadership role.
Collaboration. Women are skilled collaborators, able to work with all different people. This is an important quality for any professionals, as cross-departmental collaboration is key. Technology impacts every function in modern business, and those most successful will be able to collaborate with all different teams and individuals.
Communication. For many of the same reasons, technologist must also be strong communicators. Communication is an area where many women traditionally excel and it’s an important quality to have. For example, communicating with the sales department may be different from communicating with the IT department. Good technology leaders will be able to speak to everyone.
Perspective. Being able to inspire a team and see the big picture are both equally important. A technology leader must be able to not only collect and analyze data but draw meaningful insights and understand what it means for the company. The ability to holistically view a situation is a competitive differentiation for organizations as well as a positive attribute that many women possess.
In the past, women had to fight a little harder to push through the barriers that have prevented women from entering STEM, but the tide is turning. In today’s new business paradigm, with a strong technology sector jobs forecast, it’s a perfect time for young women to enter computer science and engineering field.
And to help drive this point home, President Donald Trump signed two laws that authorize NASA and the National Science Foundation to encourage women and girls to get into STEM fields. The Inspire Act directs NASA to promote STEM fields to women and girls, and encourage women to pursue careers in aerospace. The law gives NASA three months to present two congressional committees with its plans for getting staff—think astronauts, scientists and engineers—in front of girls studying STEM in elementary and secondary schools. The full name of the law is the Inspiring the Next Space Pioneers, Innovators, Researchers, and Explorers Women Act. The second law is the Promoting Women in Entrepreneurship Act. It authorizes the National Science Foundation to support entrepreneurial programs aimed at women.
The stage has been set – go forth future astronauts, scientist, coder girls! Let’s rock the world.

A topic that often results in great debate is “how to measure engineers?” I’m a pretty data driven guy so I’m a fan of metrics as long as they are 1) measured correctly 2) used properly and 3) not taken in isolation. I’ll touch on these issues with metrics later in the post, let’s first discuss a few possible metrics that you might consider using. Three of my favorite are: velocity, efficiency, and cost.
- Velocity – This is a measurement that comes from the Agile development methodology. Velocity is the aggregate of story
points (or any other unit of estimate that you use e.g. ideal days) that engineers on a team complete in a sprint. As we will
discuss later, there is no standard good or bad for this metric and it is not intended to be used to compare one engineer to
another. This metric should be used to help the engineer get better at estimating, that’s it. No pushing for more story points
or comparing one team to another, just use it as feedback to the engineers and team so they can get more predictable in
- Efficiency – The amount of time a software developer spends doing development related activities (e.g. coding, designing,
discussing with the product manager, etc) divided by their total time available (assume 8 – 10 hours per day) provides the
Engineering Efficiency. This is a metric designed to see how much time software developers are actually spending on
developing software. This metric often surprises people. Achieving 60% or more is exceptional. We often see dev groups
below 40% efficiency. This metric is useful for identifying where else engineers are spending their time. Are there too many
company meetings not directly related to getting products out the door? Are you doing too many HR training sessions, etc?
This metric is really for the management team to then identify what is eating up the nondevelopment
time and get rid of it.
- Cost – Tech cost as a percentage of revenue is a good cost based metric to see how much you are spending on technology.
This is very useful as it can be compared to other tech (SaaS or other webbased companies) and you can watch this metric change over time. Most startups begin with their total tech cost (engineers, hosting, etc) at well over 50% of revenue but this should quickly reduce as revenue grows and the business scales. Yes, scaling a business involves growing it cost effectively. Established companies with revenues in the tens of millions range usually have this percentage below 10%. Very large companies in the hundreds of millions in revenue often drive this down to 57%.
Now that we know about some of the most common metrics, how should they be used? The most common way managers and executives want to use metrics is to compare engineers to each other or compare a team over time. This works for the Efficiency and the Cost metrics, which by the way are primarily measurements of management effectiveness. Managers make most of the cost decisions including staffing, vendor contracts, etc. so they should be on the hook to improve these metrics. In terms of product out the door as measured by story points completed each sprint a.k.a. Velocity, as mentioned above, is to be used to improve estimates, not try to speed up developers. Using this metric incorrectly will just result in bloated estimates, not faster development.
An interesting comparison of developers comes from a 1967 article by Grant and Sackman in which they stated a ratio of 28:1 for the time required by the slowest versus the fastest programmer to complete a task. This has been a widely cited ratio but a paper from 2000 revised this number to 4:1 at the most and more likely 2:1. While a 2x difference in speed is still impressive it doesn’t optimize for the overall quality of the product. An engineer who is very fast and with high quality but doesn’t interact with the product managers isn’t necessarily the overall most effective. My point is that there are many other factors to be considered than just story points per release when comparing engineers.

As a frequent technology writer I often find myself referring to the method or process that teams use to produce software. The two terms that are usually given for this are software development life cycle (SDLC) and product development life cycle (PDLC). The question that I have is are these really interchangeable? I don’t think so and here’s why.
Wikipedia, our collective intelligence, doesn’t have an entry for PDLC, but explains that the product life cycle has to do with the life of a product in the market and involves many professional disciplines. According to this definition the stages include market introduction, growth, mature, and saturation. This really isn’t the PDLC that I’m interested in. Under new product development (NDP) we find a defintion more akin to PDLC that includes the complete process of bringing a new product to market and includes the following steps: idea generation, idea screening, concept development, business analysis, beta testing, technical implementation, commercialization, and pricing.
Under SDLC, Wikipedia doesn’t let us down and explains it as a structure imposed on the development of software products. In the article are references to multiple different models including the classic waterfall as well as agile, RAD, and Scrum and others.
In my mind the PDLC is the overarching process of product development that includes the business units. The SDLC is the specific steps within the PDLC that are completed by the technical organization (product managers included). An image on HBSC’s site that doesn’t seem to have any accompanying explanation depicts this very well graphically.
Another way to explain the way I think of them is to me all professional software projects are products but not all product development includes software development. See the Venn diagram below. The upfront (bus analysis, competitive analysis, etc) and back end work (infrastructure, support, depreciation, etc) are part of the PDLC and are essential to get the software project created in the SDLC out the door successfully. There are non-software related products that still require a PDLC to develop.
Do you use them interchangeably? What do you think the differences are?
