Abstract
In this chapter, Hussein Al-Yaseen, Tillal Eldabi, Ray J. Paul and Ramzi El-Haddadeh attempt to obtain insights into post-implementation evaluation (PIE) in order to identify the real extent to which PIE is practised and what lessons can be learned to improve knowledge about it. In doing so, they add to the knowledge base by reviewing the current state of practice of the IT evaluation process and its types (prior-implementation and PIE) in business organisations. Secondly, understanding this complex phenomena: to explain and understand the findings of this research to gain a comprehensive picture of IT evaluation. In the chapter they identify several factors that affect the evaluation process, such as: timing of evaluation types; stakeholders and their role in the evaluation process; evaluation criteria; and the gap between Prior Operational Use evaluation (POU) and PIE outcomes. Furthermore, propelled to research practitioners 'perceptions of the evaluation process and the practices associated with the evaluation adopted within large organisations, they present the findings of a survey conducted on the FTSE 500 companies. The survey shows that around two-thirds of the 123 respondent organisations gave less importance to the PIE than POU evaluation. Of those organisations who did use PIE, some thought of it as a mechanistic process for signing off the project. The chapter demonstrates that practitioners do not appreciate the full benefits of PIE and need to be aware of such benefits. Such lack of appreciation is evidently behind the apparent scarcity of implementations of PIE, which negatively feeds back into perceptions and so forth.
