I recently wrote about why you need a definition of done, and it only seems logical to follow this up by presenting what I use for a definition of done for developing software. I use two guiding principles as the basis for constructing my definition. Potentially releasable: Ideally the software can be released (or shipped) […]

I recently read an interesting research paper titled Metrics and Laws of Software Evolution – The Nineties View by Lehman et al in the 1997 proceedings of the Software Metrics Symposium that discusses eight laws of software evolution. One set of graphs within the paper jumped out at me: they show the incremental growth of two systems over a series of releases. The graphs shared a common pattern: releases with higher than average incremental growth tended to alternate with one or more releases with lower than average growth. What are the implications of this commonly observed behavior for developing and using software? How can we use this pattern to our advantage? Read on to see my answers to these questions.
There are several strategies for producing software releases. One approach is to release by schedule – the software ships on a fixed date defined well in advance. Another method is to release based on budget – the work stops once the money available is exhausted. I believe, however, that the best strategy in general is […]
As a proponent of perpetual learning, I like to periodically take the time to reflect on what I have learned. Looking back at this past year, I definitely expanded my understanding in a number of areas based on my experiences at work and at home. My most significant growth was in the area of personal […]
The maintenance team for a typical enterprise business application must make ongoing changes to the application. In the effort to fix defects, revise existing functionality, and add enhancements, little thought may be given to the process by which these changes are deployed from development through to testing and then the production environment. However, this process […]
