Who should attend

Yellow Belts are people at the grass root level in the organisation, i.e. shop-floor employees or supervisors, those that play a vital role in bringing cultural change in an organisation and sustaining it on a long-term basis. A Yellow Belt typically has a basic knowledge of Lean Six Sigma but will not lead projects on their own. The Yellow Belt collects data, participates in problem solving exercises and adds their personal experiences in resolving the complex problems in organizations.

A Green Belt is someone who can lead improvement projects and can work independently to problem solve and improve. Often, they will work as part of a wider team under the supervision of a Black Belt who is responsible for the strategic implementation of major improvement. Most managers in mature Lean Six Sigma organisations are Green Belts so that they can incorporate improvement activity into the management of their work.

About the course

The Lean Six Sigma Yellow and Green Belt is a very practical training programme (5 days in total) that will enable attendees to immediately start applying tools and techniques to improve the efficiency & effectiveness of business processes, no matter the size or type of industry.

During the ongoing pandemic, this course will be delivered online, via zoom. If the situation changes later in the year, we may be able to revert to face to face teaching.

The training content explores the latest research in Operational Excellence and will share how these principles and techniques are applied within manufacturing, private and public service and third sector organisations. Delegates will also have an opportunity to learn how Industry 4.0 technologies blend well with a Lean Six Sigma approach. In addition, we will share examples of how lean six sigma principles and techniques to create process and product innovations to help proactive organisations adapt to the COVID 19 pandemic.

The first 2 days of ‘live online’ training, subject to passing an online exam at the end of day 2, will enable you to receive Lean Six Sigma Yellow Belt certification from Cardiff Business School, Cardiff University. The second block comprises another three days of ‘live online’ Green Belt training using Minitab software (we will provide you with a 30-day free trial version of this software).
