In Coding, Fast and Slow, I talked about one of the deepest challenges involved in writing software: the near-total inability of developers to predict how long a project will take.
Fortunately, as that post mentioned, I believe there is a way to work, where the software you write ends up being valuable, and the business people you work with end up being happy. And, critically, this way of working does not involve committing to estimates of how long work will take (which is good, because, personally, I suck beyond all belief at such estimates… even for work which I initially believe will take no longer than a single day).
In a lot of ways, this is The Most Important Thing I’ve learned in my (let’s just say many) years of being paid to write software for people.
The core idea is: put uncertainty and risk at the center of a conversation between the developers and the rest of the business (instead of everyone pretending such nasty things don’t exist). Doing so allows the entire business to tackle those genuine challengestogether.
To show what such a conversation might look like, I’m going to develop this approach in detail, in the context of a story.
