English to French Marketing Surveying

The personal report is a chronological, precise and detailed written report of the visit.
When writing the personal report, you must take into account:

- Length: the personal report has to be of a certain length, usually ¾ of a page.
- Format: full sentences, paragraphs, chronological order of events, ***case sensitivity***.
____________

Il s'agit de rapports personnels que doivent rédiger des personnes qui effectuent des tests
dans des magasins (pour tester le service, l'amabilité, etc.).

Je ne comprends pas bien le "case sensitivity"...

Merci de votre aide :)
