Keep Customer Case Studies Useful with a Freshness Review

A case study can remain valuable for years when it clearly explains what happened. Problems arise when an old story is presented as though the people, product and circumstances are still current.

Give the library an owner and a simple way to review changes.

Identify what can age

Start with the parts a reader may interpret as current: the speaker’s role, the product version, a pricing reference, an integration, the customer’s organisation and the period behind a result.

Some changes call for a small update. Others affect the central explanation. A departed interviewee does not automatically invalidate a historical story, but their title should not imply they still speak for the company.

Use a review record

This example is fictional.

Item Review observation Action
Speaker title Interviewee has moved roles Describe the role at the time of the interview
Workflow screenshot Interface changed Decide whether an updated illustrative image is needed
Result period Headline omits the measurement period Add the applicable period and scope
Customer quote Original wording still approved Retain it with its context
Proposed paid advertisement Original permission covers a website story only Hold the new use pending approval

Keeping and updating are both useful outcomes. A review should not become an excuse to rewrite the customer’s history into a current product claim.

Trigger reviews around actual changes

You can review on a regular schedule, but meaningful triggers also help: a major product change, a revised claim, a customer request, a new distribution channel or a change in the relationship.

Do not invent a universal expiry date. Set a review approach that fits the content, the permissions and the work needed to maintain it.

Make it easy for Sales to report an issue: which story, what changed and what decision is needed.

Check the places where the story appears

An updated article can coexist with an old slide, thumbnail or social caption. Keep a list of the active uses so the change reaches the material people actually share.

Where a story supports a significant marketing claim, review the context and evidence for that use. The FTC’s endorsement guidance is a useful US reference on honest, non-misleading endorsements; it does not turn an old result into a general promise.

Leave a clear handoff

Record the owner, review date, decision and next trigger. For example: “Website story retained with the historical role clarified; sales slide updated; paid social use held until the customer approves.”

This lets a colleague use the asset confidently without guessing which version is current.

For deciding which new story to commission, use the coverage audit. For maintaining the claims inside an existing story, keep the evidence register alongside this review record.
