Contradiction
Contradiction is used to describe the circumstance where a business owner wants two (or more) mutually exclusive requirements. Often these are made known in disparate parts of the specifications/scopes/charters. This does not necessarily flow from muddled thinking, although this is often the case. Nevertheless, the outcome of requiring such contradiction will result in striking very poor compromises.
Consequently, when the final solution is architected, the result is a reduction in one or more of performance, maintenance, reliability or quality of the delivered product. And that is not to mention cost and time. So I have my team carefully review the project information specifically searching for contradiction. Ideally, these are detected during workshops with the business owner before the project begins.
