My take on a software development success philosophy

by

Below I have compiled a list of  6 personal (overall) viewpoints about software development philosophy that I find particularly important when successfully running software projects. Some of them might be obvious (?), but then maybe not as I have observed that many projects don’t really adhere to them.  In fact, in many projects the opposite is done intentionally or not thus resulting in significant delays, cost overruns, unsatisfied users/customers and missed opportunities [reader: What is your take?] :

  • Quality pays – Time and resources spent on quality gives positive return on investment on development time, development costs, team and customer satisfaction etc . The earlier in development process resources are spent on quality related tasks, the better ROI. For example, is well known that finding bugs in requirements or design can be 100-1000 times less costly then in a shipped solution. Unfortunately, many projects are not managed with this fact in mind and many developers don’t have a good enough grasp of quality issues.
  • Careful risk-management is needed. – Too many projects are delayed, are over budget or completely fail to deliver. Managing the risks that can cause projects to fail is therefore essential. In particular, I find it important to limit scope of the solution/version worked on (not trying to do too many – possibly half baked – things at the same time), involve users from the beginning, consistent focus on writing well-crafted maintainable software (avoiding technical debt) and to address technical risks early on (like for instance scalability, performance or integration-issues).
  • People, development process, technology and clear goals are all important for success. Even great developers fail at projects if process is wrong, technology has major problems or goals are unclear. In particular, the value of a good R&D process is often underestimated. For larger projects, average developers all following a good software process will perform far better then great developers following a bad process.
  • Long-term priorities must be balanced with short time priorities. Quick workarounds, hacks and half-baked solutions may help to accomplish some business goals on the short term. However, unless addressed and reworked afterwards they risk permanently lowering the quality of the solution and imposing a technical debt that will effectively tax all future development. After many such short-term solutions, it is likely that development productivity will decrease substantially to the point where new features or bug fixes that should take hours will consistently take days or longer.
  • Use modern efficient technology as long as they are not bleeding cutting-edge. Be open to the use of technologies before they are mainstream if (and only if) they offer substantial benefits, are actively maintained, have a significant growing community, reasonable tool support and have books and training/support organisations behind them, Note that besides obvious technical benefits and savings, use of non/pre-mainstream technologies also helps attract the very best developers.
  • Investment in automation is key for efficient (agile) software development. Partly to save costs in the long run, partly to be more agile and responsive. In particular automate the build pipeline, deployment tasks and (most) technical tests used for regression. Beware that some automation efforts like for example GUI test automation requires special skills and tools to do right (high risk of failure or low ROI if done wrong).
