Company A case · simulation

Fictional case

Guided example · Company A

In the fictional case, Company A combines manufacturers’ press releases, patents and technical publications; no single source proves commercial adoption.

Educational simulation: fictional information and organisations.

Mistake to avoid

The register must say what each source does NOT cover, not only what it contains.

Final check

  • Is it clear which decision or need it serves?
  • Can the evidence be located, and is it dated?
  • Are uncertainties and limits made explicit?
  • Can someone else repeat or review the work?
