Not having data on sales growth does not stop you from talking about your work. A case study can be useful if it shows the task and the team's specific contribution.

Separate development results from business results

A launched catalogue, a configured form and a prepared process are verifiable results of the work. A change in revenue needs separate evidence and context. Do not attribute an economic effect to a project just because it was launched.

Show the logic of the solution

Describe the original task, the constraints, the chosen approach and the materials handed over. Mention the role of other participants if it is significant. Agree on publishing the client's name, screenshots and figures to the extent necessary.

How to build a case study from verified work

Describe the original task and constraints, then your own actions and the result delivered. If the team was responsible for only part of the project, name that part. Agree on the use of names, images and other materials. A verified ordering flow, a catalogue structure or the way data handover was organised can show a professional approach without an unverified growth story. Do not automatically link the launch to a change in sales: other actions by the company, seasonality and circumstances you do not have enough information about may lie in between.

How to describe a measurable result in context

If a figure is available and its publication has been agreed, state exactly what was measured and over what period. Do not substitute the number of enquiries for the number of customers, or visitors for sales. Separate the observed change from conclusions about its cause. If there is not enough data, explain exactly that limitation: the article shows the work done, not a proven economic effect. This does not make the case study weak. Readers benefit from understanding the solution and your role so they can judge whether a similar approach applies to their task.

What to check

  • Confirm the right to publish.
  • Name your own contribution.
  • Separate fact from assessment.
  • Remove unproven comparisons.

Example situation

Instead of “we increased sales”, you can describe the repeat-order flow you introduced and show how the client's team uses it, if this is confirmed.

Next step

A reliable case study with its limitations is more useful than an impressive story the company cannot back up.
