Evidence and Corrections

An executed model may need correction after an external effect or a review of the result. The correction workflow retains the prior revision and records a correction run with a compensating step. It creates a successor revision and an explicit compensating output, raises a verification follow-up and appends correction history. The earlier execution stays available for inspection.

For example, a simulation may have sent an output to an external service using an assumption that was later revised. The team should not silently replace the old result. The Process Owner identifies the affected revision, the Simulation Operator records the compensating action and the Evidence Steward verifies its receipt. The successor model carries the corrected path forward.

• Evidence. Documents link to a model and identify the person who verified them.
• Follow-up. Assigned actions have a due date, status, resolution and completion date.
• History. State transitions preserve actor, source revision, operation key and reason.

Define which receipts need an attachment and which can be verified through an external reference. Agree who can mark evidence verified and who will own follow-ups. Set a practical due-date policy for unresolved verification work. A follow-up marked Completed should include a resolution that tells the reviewer what was checked, especially when an external compensating output was involved.

Decide how a successor revision is named and linked to the prior one. The correction should explain both the original result and the compensating effect. If the external action’s outcome is uncertain, investigate it before starting another attempt. The organization should also agree when a corrected model needs fresh validation and review before it is published as the working reference.

Take a completed intake simulation whose specialist response needs correction. Locate the model revision, run, step and external receipt. Record the correction run and compensating step, then create the successor revision. Assign the verification follow-up to a named person and attach the evidence used to confirm the compensating effect.

Ask the Independent Reviewer to inspect both the original and correction traces. They should be able to find the old decision and explain why the successor differs. Complete the follow-up with a resolution after verifying the external effect. Check the state history for the reason, actor and revision. The outcome should be a usable current model and an intact account of the earlier execution.

• Open verification follow-ups — Track unresolved actions, assignees and due dates.
• My verification follow-ups — Work through actions assigned to you.
• Evidence to verify — Find documents awaiting a recorded verification.

Use correction and follow-up for the full trace and roles to rehearse the separation of duties.
