This is an intersting audit on the failure of the Minnesota Vehicle Registration system. What were some of the primary causes of the failure? Interestingly, many of the problems that contributed to the failure of the system were non-technical. Poor management, poor planning, poor documentation of existing business processes. Poor coding standards, poor regression testing, and lack of adequate user acceptance testing were the main things relating to technical failures. Interesting, HP was contracted out early on to write the system, but due to refusal to cooperate and their system failing to perform to expectations, they were terminated and the system was to be developed in-house. As I have read elsewhere, around the time HP was contracted to work on the system (late 2000s to early 2010s), they had a reputation of terrible management at the executive level, causing their business to loose half its value.
