What is Operational Excellence?

Operational Excellence is an organisation's ability to deliver value to customers consistently, in the most effective way, and to keep improving through its own people.

It is not a tool or a training course. It is a management system that connects strategic direction with processes, performance indicators, leadership and culture. It uses methodologies such as Lean, Six Sigma, Kaizen and change management, and integrates them into one coherent system.

Tools without a system deliver short-lived results. A system without people does not last. Operational Excellence needs both.

When you need Operational Excellence

Organisations usually call us when they recognise one or more of the following:

  • Leadership goals do not translate into daily priorities
  • The same problems keep coming back despite corrective actions
  • Many improvement initiatives, few measurable results
  • Too many KPIs, unclear KPIs, or KPIs that do not drive decisions
  • Teams were trained in Lean or Six Sigma, but application stalled
  • Growth is putting pressure on processes, people and cost
  • ISO works as bureaucracy instead of a management tool
  • You want to use AI and automation without automating waste

Operational Excellence: frequently asked questions

What is Operational Excellence?

An organisation's ability to deliver customer value consistently and effectively and to keep improving. It connects strategy, processes, data, people and culture into one management system.

What is the difference between Operational Excellence and Lean Six Sigma?

Lean Six Sigma is a process improvement methodology. Operational Excellence is the wider management system that includes Lean Six Sigma, plus strategic alignment, KPIs, leadership and change management.

Where do we start?

Usually with an OpEx Health Check, which gives a clear maturity picture and prioritised opportunities, followed by one pilot area with measurable targets.

How long does an Operational Excellence programme take?

First results from pilot projects usually appear within a few months. A full organisation-wide programme typically takes 12 to 24 months, depending on size and maturity.

Does it fit service companies and hotels?

Yes. The principles apply to every process with a customer, external or internal. For services we use our Lean Service Excellence approach.

How does it relate to ISO 9001?

An Operational Excellence system gives substance to the quality management system: clear processes, KPIs, risk thinking and continual improvement. With our Lean ISO approach the system becomes leaner and more useful.
