What’s The Point of Code Craft?

A conversation I seem to have over and over again – my own personal Groundhog Day – is “What’s the point in code craft if we’re building the wrong thing?”

The implication is that there’s a zero-sum trade-off between customer collaboration – the means by which we figure out what’s needed – and technical discipline. Time spent writing unit tests or refactoring duplication or automating builds is time not spent talking with our customers.

This is predicated on two falsehoods:

  • It takes longer to deliver working code when we apply more technical discipline
  • The fastest way to solve a problem is to talk about it more

All the evidence we have strongly suggests that, in the majority of cases, better quality working software doesn’t take significantly longer to deliver. In fact, studies using large amounts of industry data repeatedly show the inverse. It – on average – takes longer to deliver software when we apply less technical discipline.

Teams who code and fix their software tend to end up having less time for their customers because they’re too busy fixing bugs and because their code is very expensive to change.

Then there’s the question of how to solve our customers’ problems. We can spend endless hours in meetings discussing it, or we could spend a bit of time coming up with a simple idea for a solution, build it quickly and release it straight away for end users to try for real. The feedback we get from people using our software tends to tell us much more, much sooner about what’s really needed.

I’ll take a series of rapid software releases over the equivalent series of requirements meetings any day of the week. I’ve seen this many times in the last three decades. Evolution vs Big Design Up-Front. Rapid iteration vs. Analysis Paralysis.

The real customer collaboration happens out in the field (or in the staging environment), where developers and end users learn from each small, frequent release and feed those lessons back into the next iteration. The map is not the terrain.

Code craft enables high-value customer collaboration by enabling rapid, working releases and by delivering code that’s much easier to change. Far from getting in the way of building the right thing, it is the way.

But…

That’s only if your design process is truly iterative. Teams that are just working through a backlog may see things differently, because they’re not setting out to solve the customer’s problem. They’re setting out to deliver a list of features that some people sitting in a room – these days very probably not the end users and not the developers themselves – guessed might solve the problem (if indeed, the problem was ever discussed).

In that situation, technical discipline won’t help you deliver the right thing. But it could help you deliver the wrong thing sooner for less expense. #FailFast
