SYSE.22:2 - Problem

The usual failure is a frozen pair: one backlog becomes the problem and one baseline becomes the solution. Local optimization continues after a relevant condition changes—for example, intended use, environment, a protected characteristic, a supplier condition, or the reachable System family.

Another failure retains many alternatives without their identities and rules. A single portfolio mixes records of unlike kinds—for example, signals, problem formulations, architectures, configurations, experiment proposals, and decisions. A moving Pareto Front then hides changes in its candidate set or comparator and appears to demonstrate improvement across incomparable questions.

Reopening everything after every signal is equally costly. The project needs dependencies and currentness conditions for individual claims so it can revise a problem without restarting unrelated Work.
