Information Model

Hypothesis:

Functional requirements contained in the brief can be:

• formalized into Engineering models(mechanical, industrial, software engineering)

• explicitly tracked in the Functional Diagram

Discussion/Conclusion

13

• Post application of the contribution (due to time issue)

• Validate its applicability (first step before doing it on real project)

• Relevancy agreed by professionals through interviews

Next step:Validation in ‘‘real conditions’’Brief-Project adequacy on a University Library (Luxembourg)

Thanks for your attention!
