Developing requirement model for a web-based E-procurement system in Nigeria

Abstract

The manual approach to public procurement of works, goods, and services is characterised by many inefficiencies. To address these inefficiencies, public procuring entities globally adopt web-based e-procurement systems developed based on requirement models, for enhanced efficiency. However, existing developed requirement models and hence, resulting web-based e-procurement systems in Nigeria are fragmented, and limited to only some components of the procurement lifecycle. This study aims to develop a requirement model capturing the entire procurement lifecycle with a view to providing a basis for the development of a holistic web-based e-procurement system for public procuring entities in Nigeria. A qualitative approach was adopted, where literature review was conducted to identify the existing manual public procurement process. A requirement model comprising of a "business requirement model (BRM) with 14 actors performing 38 business use cases and a system requirement model carrying out 91 different use cases", was developed.
