SYSE.22:10 - Rationale

FPF already supplies problem records, plural search, archives, Fronts, currentness, comparison, and choice. Systems Engineering adds the action-changing specialization: selected problem formulations must be compared with architecture- and configuration-identified System-family options under project use, operational environment, affected-System consequences, realization limits, and engineering evidence.

The terms problem factory and solution factory describe different but corresponding Work and Method structures. The described Work can take place concurrently. Identify the Systems involved separately; use SYSE.20 when overlap or required order becomes the engineering problem.
