In the early 1970s, Dr. Joseph M. Juran was one of the few experts at the time who taught Japanese business leaders how to improve quality. As more companies began to adopt the methods of Juran, William Edwards Deming, and others, Toyota's Operational Excellence movement grew. In contemporary manufacturing, Operational Excellence employs a strategic approach to achieve lean operations. 7
According to Juran's Model, there are five key components fundamental to operational excellence:8
The first component, an Integrated Management System (IMS), offers a framework of processes and standards that help define the organization's direction, identify potential risks, mitigate those risks, manage change, and ensure continuous improvement. A single integrated management system may reduce overlap, redundancy, and conflict. Early adopters of this practice include companies such as ExxonMobil and Chevron, which have implemented the Operations Integrity Management System (OIMS)9 and the Operations Excellence Management System (OEMS),10 respectively.
The second component, a culture of operational discipline, refers to the consistent adherence to established procedures and standards ensuring tasks are performed correctly and uniformly. This culture is based on five guiding principles derived from the practices of the United States Nuclear Navy. The guiding principles consist of integrity, a questioning attitude, level of knowledge, team backup, and formality. These principles define the expected behaviors of employees and explain how they contribute to achieving the goals and objectives of the organization.
The core components of the Juran Model for operational excellence are as follows:
Devised by Dr. Shigeo Shingo, the Shingo Model encompasses ten guiding principles for operational excellence. The Shingo Institute, an organization that awards the Shingo Prize, has identified "Ten Guiding Principles in the Shingo Model" as forming the basis for building a sustainable culture of organizational excellence:12
The FLEX methodology, also known as PBED (Plan-Brief-Execute-Debrief), is a structured management system originally used in aviation and later adapted for business operations in 1998.
The FLEX methodology involves four iterative steps to improve performance and align objectives:
