This paper describes how a Wales based construction company improves its operations, achieves quality standards and manages the overall business improvement through the implementation of Deming’s philosophy. The paper describes, initially how the principles are applied within the organization successfully, how they helped in managing business processes and change, it also illustrates that there was room for development in the background due to lack of continuous improvement. This paper clearly demonstrates how OPCO are moving away from turbulence productively by reengineering business processes and managing change continually with the help of Deming’s philosophy.
