A Terraform plan review should explain why each proposed change exists and what it means for the running service. Pay particular attention to replacement and deletion actions. An expected configuration difference can still imply an unacceptable interruption or loss of information if its operational effect has not been considered.
The Terraform collection includes Harun.dev Consulting, whose official site describes AWS infrastructure work. That catalogue example illustrates why infrastructure delivery needs an operating handoff as well as code. The checklist here applies to your own authorised environment; it is not an audit of the consultant's deployments.
Begin with a written change intent
State the outcome in ordinary operational terms: adjust a service limit, add an environment or replace an obsolete component. Identify which resources you expect the change to touch and which user-visible behaviour should remain the same.
Keep the intended scope beside the plan. A reviewer should be able to connect each meaningful action to the request, rather than accepting a large list because the command completed without an error.
If the plan includes unrelated drift, investigate and separate it where practical. Combining maintenance surprises with a small feature change makes both approval and recovery harder.
Understand what the plan establishes
HashiCorp's plan reference describes a preview of proposed infrastructure changes; the plan command itself does not carry them out. It also distinguishes speculative review output from a saved plan intended for later execution.
Record the source revision, target environment and variable set used to produce the artifact. Confirm that the reviewer is looking at the same environment the operator intends to change. A convincing plan for a disposable workspace does not certify production.
Recheck the final plan if configuration or remote conditions have changed. Approval should apply to a concrete artifact and its known assumptions, not to an earlier screenshot with similar-looking resource names.
Explain every replacement
For each replacement, identify the current resource, its consumers and the information it holds. Determine whether a new endpoint, credential, identifier or address will affect another component. Include dependencies outside the Terraform configuration when they are part of the real workflow.
Separate recreation of infrastructure from recovery of application data. Rebuilding a database service does not by itself restore its contents, and recreating a queue does not prove pending work survives.
Write down the expected interruption and the evidence needed to resume normal operation. If that evidence is unavailable, the review is incomplete even when the configuration is syntactically valid.
Test the recovery claim
Use an isolated environment to exercise the relevant recovery procedure. Confirm that the backup or replacement process restores the information and connectivity the application actually needs. Record the method and limitations rather than describing the existence of a backup file as a successful restore.
Avoid destructive rehearsal against live resources. A smaller representative test can answer a specific question without duplicating an entire production estate.
Approve an observable change
Name the operator, application checks and signals that would trigger a stop or recovery. After the apply, inspect the actual service endpoints and relevant logs. A completed Terraform operation is one piece of evidence, not a substitute for a working application.
The companion Terraform state handoff guide covers the ownership and recovery information the next maintainer needs. A useful plan review leaves both an understandable decision and a practical way to operate the resulting infrastructure.
