SYSE.23:0.1 - Short Practitioner Use

For a first pass, use one expected change family and one decision horizon:

1. State the change to be made, the project system-of-interest when it already exists or the intended-system claim when it does not, the configurations affected, the horizon, protected consequences, resources, DecisionSubject, chooser granularity, and authority.
2. Classify each current claim before assigning a quality bearer. Separate architecture characteristics, holder capabilities, change-Work results and resources, joint-arrangement claims, and causal or contribution claims.
3. Recover three structures when they matter: genuine part–whole or membership levels with their scale and cross-level conflicts; non-holonic dependencies or service relations between the project system-of-interest and builder arrangement; and first–then or overlapping Work.
4. Keep obtaining architecture relations and current observations separate from specifications and expected characteristics of possible-future structures.
5. Develop alternatives that change different selected structures of the project system-of-interest or builder arrangement. Show how each alternative changes option reachability, change cost, assurance, rollback, and displaced burden.
6. Compare the finite changes through C.11.CRC. Then carry the full C.11 decision record: stable OptionSet, shared comparison basis, ChoiceRule, probe cost and value when relevant, and one ChoiceResult permitted by that rule.
7. Plan, authorize, perform, and observe the chosen change separately. Later Work can support or defeat the earlier claims; the decision record does not make the architecture change occur.

This attention order is not a universal Method unfolding. Development of the project system-of-interest, development of its builders, platform service, Method change, evidence Work, and capability development can overlap, recur, or remain separate Work wholes.
