Workflow and state model
Clarify the decision and its constraints.
CAPABILITY 04 / 07 Modernize
Operational software must respect reality.
Permissions, exception paths, system-of-record decisions and integration boundaries must match actual workflows.
SYSTEM CROSS-SECTIONREFERENCE / NOT CLIENT WORK
01 / INPUT→04 / OPERATE
THE ENGINEERING QUESTION
Which transitions must remain provable?
Technology choices are a consequence of how a system should behave, fail, recover and evolve. Explore three starting situations to see the decision, the risk and the verification that would make it credible.
INTERACTIVE / DECISION STUDIO
Change the constraint.
Change the engineering choice.
These are conceptual design exercises, not evidence of an actual client delivery. Choose a situation to examine its architecture implications.
ENGINEERING RESPONSE01 / 03
Recommended starting boundary
Model irreversible transitions
THE FAILURE TO AVOID
Ambiguous status can trigger unauthorized release.
EVIDENCE TO REQUEST
State and role tests with immutable traces.
PRACTICAL OUTPUTS
Leave with decisions,
not just diagrams.
These are typical deliverable categories, not a claim that a specific client engagement is complete.
Integration and reconciliation contracts
Define the contracts and ownership that make the decision operable.
Control evidence
Verify behavior, failures, evidence and change safety.
