Is there a good book about Lean Six Sigma?

We Wrote The Book!

Lean Six Sigma for Dummies, written by Catalyst’s Martin Brenig-Jones and Jo Dowdall explains what Lean Six Sigma is, starting with the key principles and the history of both disciplines and also describes how to apply it.

How did Lean Six Sigma begin?

The name Lean Six Sigma is derived from two distinct methodologies:

  • Lean: Initially developed by Toyota, it offers a set of principles, practices, and tools focused on streamlining processes and improving customer value.
  • Six Sigma: Founded at Motorola, it’s a structured technique centred on enhancing product and service quality with a keen focus on processes.
    By fusing these strategies, a comprehensive and proven method resulted, capable of revolutionising organisations.

What’s the difference between Lean and Six Sigma?

Lean is centred around learning to find and eliminate waste in a process whereas Six Sigma is focused on eliminating the root cause of defects in a process. Both these approaches improve speed and quality and therefore cost and customer satisfaction. Combining them multiplies their effectiveness.

Who should learn Lean Six Sigma?

Virtually anyone can reap its rewards; from those in process improvement, operations, project management to those eager to amplify their professional repertoire. It’s relevant across in all businesses – anywhere there are processes – from manufacturing, healthcare to services. Moreover, it’s suitable for organisations of all scales – from start-ups to global conglomerates, and both in the public and private sectors.

How can Lean Six Sigma benefit a business?

Adopting Lean Six Sigma brings about greater efficiency, cost reduction, superior customer satisfaction, and optimal operational performance. It equips businesses with tools to pinpoint inefficiencies and chart out effective remedies while always putting the customer at the forefront.

What are the belt levels in Lean Six Sigma?

There are several belt levels, each denoting a different level of expertise:

  • White Belt: Awareness.

  • Master Black Belt: Expert level, can lead strategic initiatives and mentor Black Belts (Certification applies).

Is certification necessary to implement Lean Six Sigma?

While anyone can apply the principles of Lean Six Sigma, certification ensures a standardised level of knowledge and expertise. Many organisations prefer or require their Lean Six Sigma practitioners to be certified.

How long does it take to achieve a Lean Six Sigma certification?

Yellow Belt training takes two days, while Green Belt training lasts six days. Certification takes place following project work, typically within 2-6 months of training completion. Black Belt training is around 20 days and certification usually is completed within 6-9 months. Master Black Belt requires years of experience and additional training.
