The authors conducted research to determine whether IT‑managers, IT auditors, users, management, etc. (all decision‑makers) use a certain evaluation and selection process to acquire software to meet business objectives and the requirement of users. An argument was used that the more thorough the software evaluation and selection process, the more likely it would be that the organisation will choose software that meets these targets. The main objective of the research was therefore to determine whether Media24 uses evaluation methods and obtain the desired results. Media24 is Africa's biggest publishing group and offers entertainment, information and education 24 hours a day and served as a good example of an Internet Service organisation that made their employees available for this research project. The results confirmed that Media24 uses suggested protocol as noted in the theory for software acquisition correctly during most stages.

Active Exploration of Emerging Themes in a Study of Object‑Oriented Requirements Engineering: The "Evolutionary Case" Approach pp29-42
The evolutionary case approach provides a framework for qualitative case study research in information systems (IS). It uses revelation, reinforcement, reflection and re‑examination to explicitly explore emerging themes in interpretive case study research. The method is based on the progressive development of a theoretical model grounded initially in the literature and then refined using sequential case studies grounded in practice. The method addresses the gap which often separates data from conclusions in qualitative case study research by documenting the "revealed" and "reinforced" changes in the theoretical model as it evolves from the empirical data. The paper provides an illustrative study of the use of models in object‑oriented requirements engineering to demonstrate the use of the evolutionary case approach.
