1. Bound the project and keep two portfolios visible

Use SYSE.1, SYSE.16, and SYSE.17 to identify the actual System or intended-system designator selected as the project system-of-interest, operating environment, and Systems that may bear consequences. Use SYSE.22 to keep problem formulations and System-family options distinct but connected. Each problem has its own affected Systems, comparison and acceptance conditions, evidence horizon, and currentness. Keep each problem open to revision. Each System option has a recoverable family and configuration relation and remains connected to the problem it addresses.
