The One Thing You Need to Know… About Software Development ProcessesEdsger Dijkstra, who gave the name to Structured Programming, once said:
“Those who want really reliable software will discover that they must find means of avoiding the majority of bugs to start with, and as a result the programming process will become cheaper. If you want more effective programmers, you will discover that they should not waste their time debugging – they should not introduce bugs to start with.”
Every software development process invented has had this as its primary goal: Developers should not waste their time debugging – they should not introduce bugs to start with. And yet, a typical software development process allocates 30% to 50% of a release cycle in various stages of “hardening” (finding and fixing defects) and no one questions why this should be considered an acceptable process. In fact, finding and fixing defects at the end of a process is the hallmark of a defective process. It’s time to get back to the basics and figure out how to build quality into software at every step of the process.
