I have been watching answers to many questions on this site, and have come to the conclusion that commercial pragmatism does not factor into many software development discussions. As a result, I seriously wonder at the commercial skills within the industry, specifically the ability to deliver projects on time and to a budget. I see no indication from the site that commercially successful project delivery is a serious concern, yet the industry has a reputation for poor performance in this. Rarely, if ever, does the cost of time factor into discussions. I have never seen concepts such as opportunity cost, time to market, competitive advantage or cash flow mentioned, let alone discussed in technical answers to questions. How can you answer virtually any question without understanding the commercial background on which it is asked? Even Open source projects have a need to operate efficiently and deploy their limited resources to providing the most value for effort. Typically small start-ups have cash flow issues that outweigh longevity concerns, yet they are typically still advised to build for a future they probably won’t have if they do. Is it fair to say that these problems are solely the Managers and Project managers to solve, or are we, as developers, also responsible for ensuring successful on time, within budget delivery of projects, even if those budgets do not allow use to achieve engineering excellence?
