Concept of a Fuzzy Expert System for Story Point Estimations in Agile Projects

Estimating efforts in software projects has always been a challenging task. Great uncertainty in early phases of projects create a need for sound methods. Yet, complex mathematical models tend to be less popular amongst practitioners, making expert-based methods the most commonly used form of estimation methods. As personnel capacity and expert knowledge are known to be expensive, the need for alternative solutions, which offer reliable results whilst lowering costs, arises. Thus, this paper proposes a concept, based on fuzzy logic and agile methods incorporated into an expert system, with the goal of handling uncertainty, increasing acceptance and aiding young professionals.
