• Source: Operational excellence

Operational excellence refers to the systematic implementation of principles and tools designed to enhance organizational performance and create a culture focused on continuous improvement. It is intended to enable employees to identify, deliver, and enhance the flow of value to customers. Common frameworks associated with operational excellence include lean management and Six Sigma, which emphasize efficiency, waste reduction, and quality improvement. Organizations that adopt these practices may report increased customer satisfaction and operational efficiency.
This approach employs the tools of earlier continuous improvement methodologies, such as Lean Thinking, Six Sigma, OKAPI, and scientific management.
The concept of operational excellence was first introduced in the early 1970s by Dr. Joseph M. Juran while teaching Japanese business leaders how to improve quality.
It was formalized in the United States during the 1980s in response to the influx of quality goods imported from Japan shrinking the market share of large companies, whom deemed this trend "the crisis".




Models of Operational Excellence






= 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, W. Edwards Deming, and others, Toyota's Operational Excellence movement grew. In contemporary manufacturing, Operational Excellence employs a strategic approach to achieve lean operations.
According to Juran's Model, there are five key components fundamental to operational excellence:
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) and the Operations Excellence Management System (OEMS), 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:

Understand Juran's guiding principles, which provide the foundation for operational excellence.
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").
Recognize when and how to involve leadership and the workforce to enhance performance.
Establish an effective and efficient change infrastructure by utilizing appropriate tools and methods.
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:

Respect every individual
Lead with humility
Seek perfection
Assure quality at the source
Flow and pull value
Embrace scientific thinking
Focus on process
Think systemically
Create constancy of purpose
Create value for the customer




= The FLEX Methodology

=

The FLEX methodology, also known as PBED (Plan-Brief-Execute-Debrief), is an iterative management system initially developed for use by fighter pilots and adapted for business contexts in 1998. It incorporates elements similar to Agile's software development and attempts to emphasize flexibility and adaptation based on real-world influences, particularly through a process called debriefing.
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.
