RETRACTED ARTICLE: A systematic review on post-implementation evaluation models of enterprise architecture artefacts

Evaluating Enterprise Architecture (EA) projects is crucial to providing comprehensive information of the developed EA artefacts and assisting with the accurate evaluation of implemented Information Systems (ISs) in order to realize the achievement of EA goals and support EA decision makers. EA evaluation involves assessing the appropriateness and efficiency of each validated design with respect to predefined common evaluation criteria. The objectives of this study are to review models currently used in EA evaluation, identify the practices applied in EA evaluation, and identify current problems and areas related to EA evaluation. The aim of this study is to conduct a Systematic Literature Review (SLR) of papers referring to EA evaluation that were published between 2006 and 2014. In total, 418 papers were identified and retrieved from 6 databases. 34 primary studies were selected through the paper selection process. From the selected studies, 32 % were journal articles, 36 % were conference papers, while 32 % were contributions from book chapters. Several precise research works have been done on EA evaluation. However, there are still problems in evaluating EA implementation, including: a structured approach to EA evaluation, covering all aspects of EA evaluation, considering various perspectives, and appropriate metrics. An investigation of existing evaluation models for EA implementation shows the models are mostly inconsistent, and disunity is currently the greatest characteristic in this area. Moreover, there is no integral evaluation approach that covers all processes comprehensively.
