Content validation of an enterprise architecture (ea) readiness assessment instrument

Abstract

Although Enterprise Architecture (EA) is becoming an important agenda to align business with information technology plan, not many organisations, especially in the public sector, are ready to implement it. Therefore, there is a need to identify the readiness factors that affect the implementation of EA in the Malaysian Public Sector (MPS). Even though the readiness factors identified are influenced by a previous study, the instrument used to validate the factors needs to be re-evaluated to increase the probability of obtaining a supportive construct validity. Thus, the objective of this study is to present the content validity of an EA readiness instrument designed to validate EA readiness factors. This study used the content validity index (CVI) to quantify the relevance of EA readiness factors. To examine the content validity in the judgement stage, professional individual judgement is required. Questionnaires with four-point Likert scale were used for collecting feedback from experts. Item-Content Validation Index (ICVI) was used to check the validity of individual factors and items for MPS with experts' feedback. Seven experts with information system background specifically in EA and having a wide experience on EA implementation were selected to participate in this study. The result showed that all 14 factors and 42 items scored above 0.857, suggesting that the instrument is valid and accepted for further studies.
