Assumption-Boxing I’m thinking of maybe a new geepaw coinage: something like "assumption-boxing". This is when we frame a problem with an assumption that narrowly limits (boxes) the range of solutions. A real-world example we’re all familiar with: "Optimize meeting structure to exchange status reports on individual’s sub-projects". Do you see that "meeting structure" is a […]

What are preasons? A remarkable amount of geekery-advice comes in the form of rules & slogans accompanied by appealing. intuitively correct, theoretical reasoning using simple logic applied to pre-existing abstractions. I’m gonna pull a GeePaw-ism here and relabel "appealing, intuitively correct, theoretical reasoning using simple logic applied to pre-existing abstractions". I’m gonna shorthand these to

Have you ever noticed how much children love to help? Modern motivational theory offers us a triplet: purpose, autonomy, and mastery. (PAM) children helping surely excites P and M there. As adults we’re all slightly less desirous of helping. I attribute this to two factors. First, there’s a lot less M in it for me
Test It Where It’s Easy A basic mantra: don’t test things where they’re hard to test. A very basic application of this mantra comes up for almost every noob TDD’er: "How do I test this complex private method?" The answer is simple: make it not private somewhere else and test it there instead. If your

The Problems with Enterprise Standards I’ve been thinking lately of how much "enterprise standards" ruin our lives. When I coach in VBCA environments, I confront this problem more or less constantly. The standards can be enterprise tools, enterprise negotiations, enterprise processes. I see two factors in this. 1) solution-locking definitions, and 2) inadequate coaching reach

I spoze we should talk about scaling. There are a bunch of branded solutions to the puzzle of how to organize development of large apps with large teams. I don’t know of one that is worth the bits consumed in its logo. Yesterday I mentioned assumption-boxing, that’s when we express a problem in such a
“We were doing TDD just like we’re supposed to, but at some point it started hurting, so we not only quit, we told everyone else on the interwebs that TDD doesn’t work.” I met Kent Beck after a couple of years reading and writing around him, at the first ObjectMentor Extreme Programming (XP) Immersion, a
It happens that there are sometimes very complex changes you want to make to your code. These might involve changes to dozens of existing classes, and to the heirs of some of those, too. How do we approach this kind of situation? Recall that managing mental scope is the very heart of programming well. But

Alright, pre-coding design. By that, I mean, the serious thinking one does before one starts typing code into the computer. The first puzzle of pre-coding design is to identify when to start & went to stop. Start When You Have A Story When to start: when a story has been selected for implementation. That starting

How to Steer a Horse Coaches come to me and ask me questions that start with "How can I get them to …" There’s a quote, I’m having a hard time finding a reference, but it’s something like this… (reference appreciated) "The easiest way to steer a horse is to want to go where the
