A case study should not simply list the services performed.
It should show the problem, the engineering decision, the work completed, the verification and the final outcome.
Define the equipment issue, constraint or commercial challenge that triggered the work.
Record the inspection, measurements or technical findings that shaped the decision.
Explain why the selected repair, manufacturing, supply or replacement route was chosen.
Show the engineering and execution steps completed on the equipment or component.
Document the inspection, testing or checks used to confirm the completed work.
State the final outcome and, where publishable, the measurable impact.
That is the proof behind the work.
