Towards an Business Requirements Analysis Approach of an Information Decision Support System

The field of Decisional Information Systems (DIS) analysis and design is highly applying new techniques and methods to promote the success of the decision process and to minimize the time of design. A comparative study conducted on different approaches for analyzing decisional requirements, raises a series of problems. These problems are coming generally from the nature of the applied requirements analysis process, the difficulties in expressing requirements and the insufficient quality of documents. To face these problems, we propose in this paper a method for analyzing decisional requirements, qualified Decisional Business Intelligence (DBI), as a process and models that support the discovery, specification, negotiation and validation requirements. This approach aims to guide and orient analysts designers throughout the DBI process.
