The Juran Model

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. ^[6]

According to Juran's Model, there are five key components fundamental to operational excellence:^[4]

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)^[7] and the Operations Excellence Management System (OEMS) [8],^[8] 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:

1. Understand Juran's guiding principles,^[9] which provide the foundation for operational excellence.
2. Shift the organizational culture from viewing quality as a product attribute (often referred to as "little q") to recognizing it as a comprehensive customer experience (often referred to as "Big Q").
3. Recognize when and how to involve leadership and the workforce to enhance performance.
4. Establish an effective and efficient change infrastructure by utilizing appropriate tools and methods.
5. Focus on improving business process effectiveness and agility.

The Shingo Model

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:^[10]

1. Respect every individual
2. Lead with humility
3. Seek perfection
4. Assure quality at the source
5. Flow and pull value
6. Embrace scientific thinking
7. Focus on process
8. Think systemically
9. Create constancy of purpose
10. Create value for the customer

The FLEX methodology, also known as PBED (Plan-Brief-Execute-Debrief), is an iterative management system initially developed for use by fighter pilots and later adapted for business contexts in 1998.

The methodology consists of four steps:

• Plan: Formulating a strategy and aligning objectives among team members.
• Brief: Effectively communicating the plan to the execution team to ensure understanding.
• Execute: Implementing the plan whilst focusing on the defined objectives.
• Debrief: Analyzing the execution results against the initial plan, reflect on mistakes and learn from them to improve future performance.
