Finely grained management of software developers is compelling to a business. Any organization craves control. We want to know what we are getting in return for those expensive developer salaries. We want to be able to accurately estimate the time taken to deliver a system in order to do an effective cost-benefit analysis and to give the business an accurate forecast of delivery. There’s also the hope that by building an accurate database of estimates verses actual effort, we can fine tune our estimation, and by analysis find efficiencies in the software development process.

The problem with this approach is that it fundamentally misunderstands the nature of software development. That it is a creative and experimental process. Software development is a complex system of multiple poorly understood feedback loops and interactions. It is an organic process of trial and error, false starts, experiments and monumental cock-ups. Numerous studies have shown that effective creative work is best done by motivated autonomous experts. As developers we need to be free to try things out, see how they evolve, back away from bad decisions, maybe try several different things before we find one that works. We don’t have hard numbers for why we want to try this or that, or why we want to stop in the middle of this task and throw away everything we’ve done. We can’t really justify all our decisions, many them are hunches, many of them are wrong.

How can I help?

Hit me at [email protected] with a short note about what you'd like to do.

My roots are WordPress and publishing, and I love pretty much everything related to web development (architecture, performance, security, etc.). When not working with clients, I also maintain WP-CLI (WordPress' command line interface) and other open source projects.
