Good Developers and Technical Debt
January 12th, 2009
During one of my many discussions with James, he brought up the question “What makes a good developer?” I didn’t have any really good answers but, as most things, someone else had encountered a similar question that has given me a bit of insight. Davey Brion wrote a post on his blog ElegantCode on Ethics In Software Development:Pragmatism Over Dogmatism where he describes what he thinks is the primary goal of a developer and how writing crappy code (or maintainingcrappy code over fixing it) is counterintuitive to the goals of a developer.
A software developer’s primary goal should be to create value for the users of a system. Value can mean a lot of things here. First and foremost, it should be about things that users actually experience. Features, ease of use, performance, etc. You can get all of those with crappy code, but that leads to a situation where you won’t be able to sustain that value in the long term. A system can be very useful to its users, but if the code is in such bad shape that it can’t easily be maintained and extended with new features over time, the value of the system will slowly reduce. New features will introduce new bugs. Bug fixes will introduce new bugs. Eventually, the system starts to collapse under its own rot and the dreaded rewrite commences. Nobody really wants this, do they? If you write good, clean code from the beginning, you can usually avoid these problems.
Fix it or rewrite it … That is the question!

Sometimes you encounter things at just the right time. This article is one of those things at the right time. Please read this article if you have ever had to deal with legacy code and muttered under you breath, “Can’t we just scrap this crap and start over”, when trying to fix an issue. Below is my spin on it for the situation I am in.
