Patterns to analyze requirements of a Decisional Information System

TL;DR

This paper introduces a set of patterns using PSIGMA formalism to systematically analyze and reuse requirements for Decisional Information Systems, aiming to improve process design and facilitate adaptation across projects.

Contribution

It defines a pattern-based approach with formal representations to guide requirement analysis and promote reuse in Decisional Information Systems development.

Findings

Patterns promote systematic analysis of DIS requirements.

Formal PSIGMA representations facilitate reuse and adaptation.

Approach improves process design and knowledge capitalization.

Abstract

The domain of analysis and conception of Decisional Information System (DIS) is, highly, applying new techniques and methods to succeed the process of the decision and minimizing the time of conception. Our objective in this paper is to define a group of patterns to ensure a systematic reuse of our approach to analyse a DIS s business requirements. We seek, through this work, to guide the discovery of an organizations business requirements, expressed as goals by introducing the notion of context, to promote good processes design for a DIS, to capitalize the process and models proposed in our approach and systematize reuse steps of this approach to analyze similar projects or adapt them as needed. The patterns are at the same time the process s patterns and product s patterns as they capitalize models and their associated processes. These patterns are represented according to the PSIGMA formalism.
