What is Process Improvement?

Process improvement refers to an organised, systematic approach to analysing and improving how things are done in an organisation.

Process improvement aims to assess the current state of how things are done, analyse each step and element within the process, and implement measures to improve the process.

Structured methodologies are used to apply process improvement correctly. Lean and six sigma are the best known of these methodologies.

What is Lean Six Sigma?

It is the combination of two standalone process improvement methods: Lean and Six Sigma.

Although these methods can be used separately, they are often combined due to how incredibly effective they are when used together.

Let’s begin by outlining each on its own and then review how they work when combined.

What is Lean?

Lean targets waste. It is focused on achieving the most efficient process without compromising on quality.

The methodology originated in the manufacturing industry as an approach for streamlining production by eliminating any unnecessary or wasteful elements of the production process.

You may also hear it referred to as “lean management” or “lean culture”.

Key Tools & Phrases: Lean

  • DMAIC Cycle

    The DMAIC Cycle (also called the DMAIC Process or Model) is a core part of the lean framework. DMAIC stands for Define, Measure, Analyse, Improve, and Control.

  • The 8 Wastes

    The 8 Wastes are 8 resource areas or steps along the process to be addressed when conducting a lean process improvement initiative.

What is Six Sigma?

Many refer to six sigma as “problem solving”. When you are looking for a very simple definition, this is quite a good fit.

Six sigma is used to identify flaws or defects in a process, and to correct them. It tackles a problem (or potential problem) at the root, so that it can be prevented or resolved.

Six sigma is data-driven. It gathers detailed information and uses it to reduce variations or defects, with an end goal of a higher, more consistent quality level.

Key Tools & Phrases: Six Sigma

There are many different tools and approaches utilised within six sigma. Here are some of the best-known:

  • Kaizen Events
  • Single Minute Exchange of Die (SMED)
  • PDCA (Plan, Do, Check Act)
  • Total Preventative Maintenance (TPM)

    Combining Lean and Six Sigma

    Using each method separately will yield positive results for any business. However, the two combined can achieve game-changing savings and improvements.

    The approaches and techniques within each work easily in harmony.

    Lean will reduce the waste in the entire process. Using Six Sigma will minimise any defects or variations in your product or service.

    Let’s take a closer look at some of the benefits that can be achieved through the combined use of these process improvement titans.

    Benefits of using Lean Six Sigma:

    Once you begin to transform how you do things with lean six sigma, you will find benefits like the ones listed below.

    You are also likely to find unexpected benefits unique to your organisation.

    Here are some common benefits anyone using these methods consistently and correctly can expect:

    • Less waste
    • Lower costs
    • More efficient processes
    • Higher productivity
    • Increased profitability
    • Motivated workers
    • Improved collaboration
    • Less downtime
    • Opportunities for growth
    • Reduced errors and variation

    Why Lean Six Sigma Training is Crucial

    While the concept behind lean six sigma is very simple and seems like common sense, implementing it takes skill and a thorough knowledge of the different systems and techniques involved in both methodologies.

    Attending lean six sigma training will give you a theoretical and practical understanding, along with a level of confidence in your capability to implement.

    Getting Started with Lean Six Sigma

    When choosing a starting point for your training, you have two great options.

    • Both are suitable places to begin.
    • Both are delivered live, online by our experienced lean six sigma training professionals.
    • Both include certification.

    Green Belt Training

    Our green belt is also suited for those who are new this area. It is more in-depth than the yellow belt course, with detailed focus on both methodologies.
