What should a case study show to make a capability credible?

State the starting situation, period, constraints and the team’s role. Explain the intervention in enough detail to show what was done differently. Separate the organization’s work from the customer’s actions, other suppliers and wider conditions. A result following an intervention is not, by itself, proof that the intervention caused all of it.

For a quantified result, give the starting measure, comparison period, denominator and measurement method where relevant. Distinguish a verified operational change from a customer’s opinion. If the case is anonymized, retain meaningful context that can be supported and shared: the type of problem, scale, constraints and exact responsibility. Do not invent identifying detail to make the story sound convincing.

Use approved quotations and document permission for customer names, data and work examples. Link the case to the capability it illustrates, and keep a dated record when the offer changes. The case should support the company’s claims within its actual scope, rather than turn one project into a universal performance promise.
