Dr Diyana Abd Razak


I used to work as Quantity Surveyor and I hold a PhD degree in the subject of construction and project management. My research explore the impacts of poor quality and its impact during the post operational phase of construction projects. The focus of the project was to look at the costs of not delivering a client's requirement. Using the measurement of cost of quality, the client of a construction project and their multi-organisational supply network can address the problem of capabilities diversity that is distributed in a project's lifecycle. Importantly, the research seeks to support organisations in the construction field to better understand the cause and implication of failures and subsequently reducing the cost of bad quality, specifically at the post-operational stage. The research also ascertains what could be done to share information of failure throughout the construction supply network, and to create a shared culture of quality between partners. The need for integration capabilities between client's strategic requirement, technical project delivery, and functional operational management in mitigating failures is reiterated throughout the research.
