“ISO 9000 is only a beginning; it provides a mechanism with which to bring about systematic improvement but it does not improve performance byitself”. Paying attention to the above statement made by Hoyle (1994) on the value of ISO 9000 certification and its diverse nature, the following questions will be clearly investigated in this work: Does ISO 9000 certification have a significant positive effect on business performance? What is the organisational attitude towards ISO 9000 certification? Providing answers to these questions above will lead to a clearer understanding of the impact of ISO 9000 certification on business/organisational performance. It will also guide to a realistic management expectation of business value of ISO 9000 certification in an organisation and the knowledge that gaining an ISO 9000 certification is noting similar to creating quality organisation. Research methodology This research seeks to review some extant theoretical literatures and web-based sources on the impact of ISO 9000 on business performance.

These studies include 🙁 Magd, 2008; Terziovski et al., 2003; Lee, 2003; Chow-chua; 2003; Sun, 2000; Dick et al., 2002; Heras et al., 2002a etc.). Several papers associated with ISO 9000 are mainly focused on the qualitative benefits associated with its certification, like communication and general understanding of the company’s process, and not the quantitative benefits. Some literatures also focused on what to do to gain ISO certification. Perceived benefit of ISO 9000 certification ISO 9000 certification bodies such as the British Standards Institute (BSI>
