Discipline & Operational Excellence

What is Operational Discipline?

Operational Discipline is not about punishment or sanctions, it is not negative – it’s a key ingredient for manufacturing excellence.

Operational discipline is a mindset, a way of thinking about a situation and then behaving in a manner that is a foundation for operational excellence.

Operational Discipline is about consistency and rigor in all aspects of a business

There is a famous quote from one of the founders of the Toyota Production System, Taichi Ohno, which says “there can be no improvement without standards”. A useful qualification to that quote could be ‘the standard must be followed with discipline (consistency and rigor)’.

Consistency means – reliability, regularity, steadiness – if something is an important contributor to the success of our business then it must be looked after and reinforced.

Rigor means – thoroughness, attention, strictness – if something is an important contributor to the success of our business then it must be respected absolutely.

If today’s standard is the foundation for tomorrows improvement, we need to have solid standards.

  • Do the right task
  • Do it the right way
  • Do it at the right time
  • Do it every time

If we don’t have the operational discipline to take care of our standards, we will not be able to realize the efforts of our improvements. For every two steps we take forward we could easily take one step backwards.

 

Without Operational discipline – no standards – no sustaining

With Operational Discipline – each improvement builds on the last

Improving a manufacturing quality KPI is easier when a process is in control – when there is operational discipline around known standards. In chaotic situations the root cause of failure is more difficult to identify because of the ‘system noise’. The effect of improvement efforts can be difficult to relate into performance because there are so many moving parts.

Operational Discipline around standards – what type of standards are there, how do we discover them, how do we sustain them, and how do we improve them?

Discovering standards – The simplest approach is to consider the 4M’s:

  • Machine – reliability and predictability/precision – disciplined maintenance (maintaining standards), clearances, tolerances etc. Identifying and maintaining machine standards. Autonomous Maintenance, Planned Preventative Maintenance pillars in a TPM approach.
  • huMan – consistent knowledge and skill to maintain a process, carry out a task, lead a team. Providing the most efficient and effective training standard reduces variation.
  • Method – standardized, optimized, and defined method/tools to perform a task. The best method will be discovered and evolve through the use of Continuous Improvement/Kaizen activities.
  • Material – Product development, engineers, purchasing, and quality assurance are typically familiar with standards – in the form of material and product specifications.

Sustaining Standards

Sustaining standards is the essence of Operational Discipline as laid out in this article. Examples of commonly understood standards are described above, some more advanced concepts are described below.

Sustaining standards requires clear ownership. Ownership can be documented and given but needs to be understood and taken. Educating the organization on the broader concept of standards and involving them in developing the standards will facilitate associates taking ownership. Leaders have to provide the structure, framework, and the time to allow associates to take care of their standards.

Having an Operational Excellence or Performance System builds the framework to discover, sustain, and improve standards in a consistent and rigorous manner.

Improving Standards

Improving standards is the aim of Continuous Improvement activities. Each improvement activity we run should develop new standards or improve existing ones to generate better performance from the process we are working on.

Example:

  • An operator as part of a daily shift report is out looking for ways to improve performance by eliminating losses
  • Chartering improvement teams involving improvement engineers
  • Optimizing a business process

Performance Solution by Milliken recently worked with a client who had been manufacturing the same product for over 30 years. The market was expanding, and new competitors were entering. The product has very high-quality requirements due to the nature of its use and highly regulated.

The opportunity we saw was the quality yield rate. After 30 years of experience the site still had huge potential to improve. A combination of:

  • workshop activities to discover and formalize existing standards involving production, maintenance, and subject matter experts
  • clearly defined defect reduction projects (DMAIC) to improve standards and uncover new ones
  • building standard work, layered audits across all relevant functions to sustain the optimized standards

led to a reduction quality yield loss of 75%.

Expanding on the idea of operational discipline we should also consider a broader scope

Leadership operational discipline

Leader standard work – creates expectations, provides cadence and consistency. The subjects that leaders devote time to demonstrates what is important. Standard work including layered auditing of standards displays and supports operational discipline. Leadership must reinforce operational discipline not only in what they say but also in what they do. Standard work is a tool most often associated with Lean Manufacturing but is not exclusive to that approach and should be considered as an important ingredient in establishing manufacturing excellence across different approaches.

Leadership behaviors – have to be consistent/disciplined. Not about being robots but is about consistently providing direction, involving everyone, expecting the best and recognizing contribution. Every day.

Process Discipline

Operational Excellence is a series of connected processes/systems.

Processes are effective when they are used in a disciplined way – for example

  • A strategy deployment process sets the priorities and direction for an organization; it must be kept updated and routinely communicated to align and engage the organization.
  • Continuous Improvement – a reliable process to make improvements. If we have a proven process/approach to get better, for example DMAIC, then it makes sense to practice using this process. Not only to deliver improvements in a predictable manner but to build upon our experience, develop expertise, and improve our capacity to improve.

Organizational discipline

The optimum performance of an organization relies on the application of operational discipline across functions, departments, and hierarchies because of inter-dependencies.

Operational discipline can only be effective when adopted by the whole organization. Quality manufacturing relies on each of the types of standards we have discussed above being managed by the appropriate part of the organization to strive for zero defects.

Organizational discipline relies on a framework. Building a management system that visualizes the roles and responsibilities for standards is the role of a pillar in the operational excellence system that Performance Solutions by Milliken has developed based on its own manufacturing experience. A Daily Management System is a fundamental part of the routine of each vertical tier of an organization and each horizontal function. The establishment of review and response meetings brings together the functions and departments. It’s all about the right people looking at the right topics on the right frequency in a routine and rigorous way.

Summary

Operational Discipline is a mindset, a way of thinking, but it can be realized in a number of very concrete and tangible ways. It doesn’t just exist in people heads; it can be brought to life in every facet of an organization.

As is often the case establishing Operational Discipline requires leadership commitment; a robust structure; associate engagement and a change agent to teach, coach and mentor.
