A software handover should prove one recovery path
Before agreeing to support an unfamiliar application, ask a practical question: can the team recover one important workflow using the handover material? A walkthrough turns missing context into specific work before an ongoing support arrangement is scoped.

When considering a software handover for an unfamiliar application, it is crucial to assess whether the provided materials can effectively support the recovery of a key business workflow. To begin, identify a routine business process that the organization relies on, such as accessing a dashboard and exporting a report. Clearly define the desired outcome, the information source, and designate an individual who can verify the accuracy of the result.
Conduct the walkthrough in an isolated test environment using dummy or appropriately redacted data. Record the running version, source revision, deployment reference, and environment. It is essential to have access boundaries defined, including the individuals permitted to investigate, deploy, and restore. Document the process of obtaining authorized access, ensuring that credentials are kept separate from the runbook.
Trace the chosen business path, listing the necessary services and data stores. Include any scheduled jobs that must be completed before the expected result is current. Make any potential failures visible by describing what users see, the monitoring indications, and the evidence that distinguishes a stale result from an unavailable service. Agree on who will investigate any alerts that arise during the testing process.
To thoroughly validate the recovery process, rehearse it in an approved test environment. Document the test date, version, outcome, and any remaining limitations. Remember that a successful file restore alone does not guarantee that the business workflow will function correctly. Identify any work that may have occurred after the restored point and establish how it will be reconciled without re-running operations that could lead to duplicate or irreversible effects.
Assign responsibility for the next decision, specifying who can approve a rollback, pause a workflow, or accept a temporary workaround. Clearly outline the escalation route and expected contact window, keeping in mind that 24/7 coverage may not always be guaranteed. Store a concise runbook, relevant references, and unresolved items in a location accessible to the authorized support team. Have another individual follow the runbook to identify any areas requiring additional assistance.
When creating a new support enquiry, use the following outline: system and business owner, the workflow that must continue operating, the observed problem and its business impact, known version, dependencies, and access owner, recovery evidence already available, unresolved risks and decisions, and the required support window. Distinguish between one-off stabilisation work and ongoing scope.
Remember that the walkthrough informs the scope but does not guarantee a specific response time, certification, or production readiness. It is essential to agree on responsibilities, included work, and exclusions based on the actual system's requirements. Additionally, clarify repository ownership and incident responsibility through separate agreements, such as GitHub's CODEOWNERS feature or Google's Site Reliability Engineering book on emergency response.
