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

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.
