  • I have tried to make a contribution to this group, and I do hope that I have had some success. But I am now a little tired of the snipes and barbs that my offerings seem to elicit. So, I have decided to retire from the field and cease to participate in this group. This may be interpreted as me throwing a hissy fit, or taking my bat and ball and going home, or whatever other motive...

  • I have always had the impression that trying to 'update' a legacy system, in the way that I think you are indicating, can turn into a quick sand swamp of frustration and fire fighting (excuse the mixed metaphors). I honestly think that it is usually better to use the legacy system as a 'prototype' for the new system, and, instead of trying to patch the old system, you develop a...

  • I fail to see how anything I have said can be interpreted as me wanting 'to spend as much time as I want cycling around bugs'. Where did this thought come from, George? This is the same sort of nonsense that some others have offered, about me liking bugs, or trying to get 'credit' for bugs, and other similar stuff and nonsense. It is also just as helpful as the comments about...

  • This is a strange question ... content fatigue ... delivering sprint in and sprint out ...lose sight of the bigger picture architecturally. First, I would wonder if the team ever had a Vision Phase, where the worth and value of the project was made clear. And if things have changed so much since then that a new vision needs to be created. I ask myself 'What is this 'architecture...

  • If you find a defect in the features being developed in the current sprint, then you fix them. If that means that the story is not finished by the end of the sprint, you do not count the story points in the velocity. The story is not 'done'. Creating a defect, then finding it, and fixing it, in the work currently being done in this sprint would never imply that the story points...

  • I found this in my Drafts box ... apparently it didn't get sent before. I don't want to waste it, but this may be the 2nd sending. Ron, I am unable to provide the treatise on velocity that you ask for. In fact, I don't even see the relevance of doing it. In my various readings about agile development, I have developed the view that velocity is a figure that is calculated...

  • Back in 1976, a guy called Peter Chen wrote a paper on Entity Modelling. He was an academic. His paper has been claimed to be the most cited academic paper in IT/CS publication, and is the seminal work on ER Modelling. Over the years, many people (usually American academics on the tenure track) have written books that include discussion on ER Modelling. Many of them have added a...
