An assumption is made that if the work is finished on time, within the agreed budget and set quality (golden triangle), then the project is deemed successful. Available evidence suggests that this is far from the truth. Hence, the construction industry needs to pay special attention to critical success factors, besides the golden triangle, if it is to survive the challenges posed by globalization. The critical success factors are encapsulated in components, that is, comfort, competence, communication and commitment (COMs). These components make up the four COMs model which forms the basis of this book. This book therefore provides a detailed analysis on how to increase the likelihood of achieving project success in the construction industry. The analysis given should be helpful to professionals in the construction industry, especially project managers and contractors who are finding it difficult to attract new clients.
