## Short answer

The demo succeeds but the team has not tested failures or recovery. Start with this check: List the ordinary workflow and one important invalid, missing or delayed input case. The corrective action is to include exception handling, access boundaries and export or recovery in acceptance testing.

## Key takeaways

- List the ordinary workflow and one important invalid, missing or delayed input case.
- Include exception handling, access boundaries and export or recovery in acceptance testing.
- A synthetic test should not be represented as a complete production reliability assessment.
- Review required workflows passing ordinary and exception cases.

The demo succeeds but the team has not tested failures or recovery. The useful response is a diagnosis that changes a decision, not another report describing the symptom. Use this play with the workflow owner with the relevant data and access owners. The working evidence should include requirements, acceptance tests and exit or recovery plan, with private or sensitive details removed from any shared example.

## Confirm the problem in the actual workflow

List the ordinary workflow and one important invalid, missing or delayed input case. Start with one representative case and follow it from the original action to the reported outcome. Identify where the observed behavior first differs from the intended process. A screenshot of a final dashboard can be useful, but it may hide the source record, a delayed update or a decision made elsewhere.

Keep the unit of analysis explicit: a maintained business workflow rather than an installed application. The same label can conceal different populations or stages. Before comparing two results, check that they describe the same kind of work and have had a comparable chance to complete it.

## Separate the visible symptom from the cause

Evaluate the tool using ordinary work and an important exception. Confirm data ownership, sync behavior, access boundaries and the information needed to leave the product. A successful demonstration does not remove the need for an internal operating owner.

The symptom in this case is specific: the demo succeeds but the team has not tested failures or recovery. Ask which piece of evidence would distinguish an operating failure from a measurement failure or a mismatch in the original plan. If the evidence is unavailable, record the missing source and its owner instead of treating the preferred explanation as established fact.

## A situation to work through

A form connector needs a response to rejected writes and duplicate events, not only proof that one clean submission arrives.

This is an illustrative situation, not a reported client case. Record the equivalent evidence and assumptions for your own workflow.

## Choose the smallest useful correction

Include exception handling, access boundaries and export or recovery in acceptance testing. Keep the change narrow enough that the responsible people can implement and inspect it. If a correction changes several things at once, describe it as a combined operating change; do not later claim that one small element caused the whole result.

Assign the correction to the workflow owner with the relevant data and access owners. Agree which artifact will show that the work is complete. An owner without an observable acceptance condition can close a task while leaving the original problem unresolved. A detailed checklist without an owner creates the opposite problem: the evidence requirement exists, but nobody is accountable for producing it.

## Preserve the important limitation

A synthetic test should not be represented as a complete production reliability assessment. This condition belongs beside the recommendation because it can change the decision. It should not disappear when the plan becomes a short presentation or a status update.

An integration can move one clean record successfully while mishandling updates, retries or deletions. A small permitted test should include those conditions before a production rollout. Record which behaviors were verified and which remain assumptions.

## Verification worksheet

| Review item | What to record for this issue | Owner | Evidence |
| --- | --- | --- | --- |
| Observed symptom | The demo succeeds but the team has not tested failures or recovery. | | |
| Diagnostic test | List the ordinary workflow and one important invalid, missing or delayed input case. | | |
| Proposed correction | Include exception handling, access boundaries and export or recovery in acceptance testing. | | |
| Guardrail | A synthetic test should not be represented as a complete production reliability assessment. | | |
| Review measure | Required workflows passing ordinary and exception cases | | |

Download a working copy and follow the [worksheet instructions](/resources/#using-worksheets). Keep unknown facts visible rather than filling gaps with guesses.

## Decide whether to keep, revise or stop the change

Review required workflows passing ordinary and exception cases after the agreed observation period. Keep the correction when the intended behavior is verified and the guardrail remains acceptable. Revise it when the diagnosis was useful but the intervention did not resolve the cause. Stop and reassess when new evidence shows that the original problem was framed incorrectly.

Record what changed in requirements, acceptance tests and exit or recovery plan. This gives the next review a stable starting point and prevents a definition change from being mistaken for a performance improvement.

## Frequently asked questions

### What is the first diagnostic check?

List the ordinary workflow and one important invalid, missing or delayed input case. Inspect the actual working record or customer path rather than relying only on a summary report.

### What should change after the diagnosis?

Include exception handling, access boundaries and export or recovery in acceptance testing. Record the owner and the evidence needed to verify the correction.

### What limit should the team keep visible?

A synthetic test should not be represented as a complete production reliability assessment. A local improvement does not establish a universal benchmark or guarantee a commercial result.

### How should the correction be evaluated?

Review required workflows passing ordinary and exception cases using a consistent unit and observation window. Keep the original evidence and record any measurement changes.
