SYSE.17:4.1 - Perform the Move

1. Name the focus and receiving decision. State the proposed alternative or change, the actual System or intended System referent and configuration to which it applies, the use situation, relevant scope and horizon, and the engineering decision that can use the result.
2. Generate consequence-producing situations. Consider Work and events that may expose the alternative’s consequences—for example, realization, intended use, maintenance, plausible misuse, failure, recovery, retirement, or later modification. Retain only situations whose consequences could alter the receiving decision; these examples do not impose a lifecycle.
3. Trace outward without promoting hypotheses to facts. Follow supported obtaining relation occurrences separately from modal consequence-path claims. For each modal path, name candidate participants and proposed relation kinds—for example, material transfer, energy transfer, information transfer, exposure, access, resource use, an economic relation, or an institutional relation—together with conditions, evidence, uncertainty, and the useful consequence or limit for this decision. A modal path does not itself select a probe.
4. Recognize the bearer. Identify each actual System from evidence about its identity and boundary. A role label, organization name, collection, description, or representative can help locate a candidate but does not establish that identity. Keep a possible-future bearer as an intended System referent in the claim until the System exists and can be recognized. State what remains unknown when recognition needed by the decision fails.
5. Qualify the consequence. State the characteristic or condition that may change, bearer, configuration, conditions, direction or magnitude cue when known, interval, and uncertainty. Distinguish an observed occurrence from a modal claim. State the evidence basis—for example, observation, measurement, simulation, model-based prediction, or a bounded expert estimate—and its limits. Use C.28 when reliance depends on a causal, intervention, or counterfactual claim.
6. Add value and specialist claims only when needed. Name the bearer and value frame for a value-qualified consequence—for example, a claimed benefit, harm, burden, opportunity, or accepted loss. Preserve conflicts and distributions. Select any specialist acquisition through A.15.9 and C.11.DUA before sending the question with its System, claim, evidence, and receiving decision; keep the returned authority boundary visible.
7. Change the engineering choice. Add or revise a decision contribution—for example, a constraint, alternative, probe, safeguard, monitoring condition, reversible step, refusal, or escalation. When that contribution relies on permission, authority, responsibility, or representation, establish the required relation separately.
8. Finish with the useful answer and its material uncertainty. A qualified consequence account, constraint, alternative, or explicit unknown can complete this use. Select a further discovery action through C.11.DUA only when its obtainable contribution warrants the full preparation, access, performer, interpretation, delay, displacement, and downside. Compare observations separately and together against shared resources and the decision window. Retain the residual and reopen condition that matter to the receiver; an unselected inquiry needs no proposal or omission certificate.

The numbered presentation is an A.22.CGUS learning unfolding, not a required Work sequence. Discovery, design, trial, specialist inquiry, and consequence observation can overlap and reopen one another.
