The Importance Of Team Composition

I think a lot about process, process improvement, productivity, and efficiency vs effectiveness (believe it or not the difference is not universally understood).  Lately I’ve been thinking a lot about team composition and how it affects the productivity of the team.  In part I’ve been thinking about it because of the teams I’ve had in the past; in part because I’m currently hiring and having to make trade-offs like salary level vs skill level and overlapping skill sets, but also because I’ve been playing the game Overwatch a lot, where team composition essential.

MVP is a VIP (Very Important Practice)

MVP stands for (in this article) Minimum Viable Product. It’s not an Agile concept.  It’s not even a software-specific concept, though it’s certainly easier to do with software, since upgrading software is usually easier than upgrading hardware.  The concept is simple: Instead of building every feature under the sun into your product then releasing it, build the least you think people will buy and release that, following up with more feature-rich versions.  There are several good reasons to do this.

Two Java Phone Screen Questions

When I phone screen a Java candidate, I ask just two technical questions to assess their competency and give me a feel for where they are on the scale of “Heads-down coder” to “Java Software Engineer”.  In general, I try not to discount any candidate on just one factor, because we all have different weaknesses and strengths.  That’s why I consider these assessment questions instead of must-haves.

This is especially true of SQL questions in interviews.  I am way more interested in their thought process and how they come up with an SQL query than I am the query they respond with.  I’m not testing whether they have SQL syntax memories; I’m testing whether they understand how relational data can be joined and aggregated and filtered to produce the desired results.

What does your company maximize?

I heard a CEO say the other day that “Charity is not a business model”.  I’m not so sure that’s the case, but it got me thinking.  And researching.  It turns out that companies (and their executives) are not legally bound  to maximize shareholder profits, as many people (including myself, until now) think.  Businesses can form to, and focus on, maximize any collection criteria they want.

Why Is Performance Management So Taboo In Agile?

Performance evaluations and performance management are areas I disagree with many Agile coaches’ opinions on. “Popular opinion” is that you don’t evaluate individual team members at all. You only evaluate the team as a whole. They maintain that team members are self-motivated and will do their best to support their team. They also feel that evaluating individuals on the team could lead to stratification, and all team members should be treated equal and be at the same level. What I propose is to evaluate individuals, but to emphasize team support and commitment in the evaluation.

Binary Is Bad

“Only the madman is absolutely sure.”  ― Robert Anton WilsonMasks of the Illuminati

Nothing in this world is completely black or white, good or bad.  The human brain likes to categorize things.  Put things in neat little buckets, so it can think of groups of things, and assume all things in that bucket have certain attributes. When that happens during a decision-making process, though, you’re throwing away information before assessing its value.  As soon as you feel you’ve categorized it you let go of the information that went into that categorization.  Incomplete information is the enemy of sound decision-making.  Sometimes you need to make snap judgements when timing is of the essence, but even then it should be a first approximation, to be re-evaluated later.
