A.1.STM:0 - Practitioner entry
Use this when. Use this pattern when a project team has, or is choosing, one common project system-of-interest but cannot tell which answer is missing on the map from the change expected outside that system to the work and systems that make or change it, and onward to the work and systems that make or change those builders. Use it also when a local result has no supported next fact connecting it to production or change, release, runtime use, or that outside change.
First useful move. Name the final result that matters now: a release, runtime use, or specific change expected outside the project system-of-interest. If a local result is current, say exactly what it is about and name the next supported fact needed to connect it to production or change, release, runtime use, or that outside change. Read backward only far enough to name the first answer that is absent, stale, disputed, or unsupported. Then state that exact question and use the one subject pattern whose Use this when accepts it as a locator for the required definition or constraint.
Memorable reminder.
Start with the change needed outside the system the project is about. Choose that system and its boundary by that use; only then choose its inside. Ask how it will be made or changed, who or what can do that work, and what must make or change those builders. Read backward to the first unsupported answer. Follow real work and changes forward; for each local result, name the supported next fact that connects it to production or change, release, runtime use, or the outside change—or stop where that fact is missing.
This reminder is the Plain long mantra. Section 4 gives the working steps for using it.
Not this pattern when. If the current question is already one system-recognition, project designation, service/access, architecture, Method, Work, transformation, TFS/network, causal-use, evidence, or assurance question, use that direct pattern and stop there. Do not traverse the long map merely because a project mentions a project system-of-interest.
What this buys. The practitioner returns one located gap, one subject pattern, and one next question or action—or a truthful stop.
