a conceptual model for building requirements processing
DESCRIPTION
In a brief, the functional diagram comprises information related to activities and flows at an abstract level. It serves as a basis for architects to develop their architectural concept. Brief is therefore a first requirements processing proposed by the programmer, constraining architects’ solution space. The usual issue is that this processing is only described in the brief, spread in the text and difficult to track or update. This research work aims at providing a design artefact to support and formalize the requirements processing summarized in functional diagram. This article describes the concept of meta-space. Meta-space diagram covers more requirements than the functional diagram and provides several analysis viewpoints to the programmers for performing the requirements processing. This contribution is developed from observations made on architectural programming theory and practice on a real construction project. Tools/techniques from other engineering domains are used to design and consolidate the proposal. A preliminary case study illustrates its application on a built multimedia library.TRANSCRIPT

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!
