Lean Six Sigma Yellow and Green Belt training course

'Six Sigma' is a well-established approach that seeks to identify and eliminate defects, mistakes or failures in business processes or systems.

It achieves this by focusing on those process performance characteristics that are of critical importance to customers. 'Lean' offers a set of proven concepts, tools and techniques which reduce lead times, inventories, set up times, equipment downtime, scrap, rework and other wastes, and increases the quality of a product or service. The integration of these two improvement methodologies can achieve fantastic results, far greater than the deployment of one methodology alone.

The five day Lean Six Sigma Green Belt training is a very practical programme that enables attendees immediately to start applying tools and techniques for improving the efficiency and effectiveness of business processes, irrespective of type or size of industry. Attending the first two days of the programme will enable participants to achieve a yellow belt accreditation, whilst completing the five-day programme allows progression to green belt.

Your trainer will be Maneesh Kumar.

Who it’s for

A Green Belt (GB) is an individual who works on improvement projects part-time (20%), either as a team member for complex projects (supporting Black Belt) or as a project leader for simpler projects.

Most managers in mature Lean Six Sigma organisations are GBs. Generally, GB projects may address processes that are not cross-functional. Typically, a GB project has a bottom-line impact of approximately £30k-£35k per year and should be completed within a span of three to four months. The project must have followed Lean or Six Sigma methodology and have applied relevant tools and techniques of Lean/Six Sigma.

Attending all five days of the training and carrying out a Lean Six Sigma project (essential criteria) will lead to Lean Six Sigma Green Belt certification. If delegates attend the first two days of the training programme only, they will receive a Lean Six Sigma Yellow Belt certification from Cardiff University. You are not expected to conduct a project to get a Yellow Belt Certification.
