KCAE.USE:1 - Problem frame
Use this when you are constructing, buying or changing access to a documentary corpus and several technically feasible arrangements would serve different uses. The governed object is that access arrangement under a workload. The first useful result is a bounded design question with credible alternatives, sources, receiving results and decisive constraints. You need access to representative work and someone who can settle the relevant source authority and data-flow rules. If one known source already answers a one-time question, use it directly.
