Six Sigma Training – Green Belt Yellow Belt)

Course details

This Six Sigma Training Green Belt Yellow Belt programme is designed for all organisations regardless of size, complexity and sector. The practice of Six Sigma enables the measurement and removal of variation and waste from within functions and processes. Its history lays in manufacturing but it can and is used in many different areas of commerce and industry.

What you will gain
The methodology in this programme is project based using the DMAIC approach, consequently, the training is deployed and can deliver bottom-line results very quickly.

For organisations that already have a continuous improvement programme, this course will make it more robust and broaden the available skill set.

DMAIC stands for Define, Measure, Analyse, Improve, Control

DMAIC: Using the following tools and techniques:

  • Global 8D
  • Statistical Process Control
  • FMEA Failure Mode Effect Analysis
  • Design of Experiments


  • Using the Global 8D process to identify the issue and construct the team.
  • Preparation – Does the problem warrant a team approach to eliminating the problem?   If yes the ranking system will be used to determine status.  If the client does not have this a system will be developed as part of the workshop.
  • Exercise: This will be supported with some simplistic prioritisation exercises – it would be appropriate to use some existing examples i.e. list of historical problems for participants to grade, to test understanding of the prioritisation rankings.
  • Establish the Team – Examination of the importance of team composition etc: – Explanation of why team efforts far exceed individual efforts.
  • Exercise: The power of the team exercise, to illustrate Silo v Team thinking
  • At this point the client specific exercise is introduced – the delegates will be split into teams with a simplistic exercise assigned to determine ideal team composition for the particular case study.
  • Exercise: Defining the client specific problem – the case study

Root Cause Analysis – Analyse for root cause and verify the escape point.
Exercise: A number of additional tools will be introduced including:

  • Fishbone (including how it happened and how did it get out)
  • Measles charts
  • Process flow charts
  • Comparative Analysis – as per the workbook
  • Exercise: Root cause analysis on a case study using the comparative analysis framework – if necessary redefine the problem description

Design of Experiments – depending on the complexity of the issue, this enables the organisation to eliminate re-occurrence of more complex problems.

  • Exercise: Introduction to Design of Experiments
  • An introductory insight to the methodology related to the “Design of Experiments” (DoE) the Taguchi method
  • The workshop will provide a basic practical insight to DOE with emphasis on the Taguchi method.

Workshop content:

  • What it is
  • How it can be applied
  • An outline of a Taguchi 4 parameter 2 level experiment
  • The learning process will be enabled by simple practical examples.

Failure Mode Effect Analysis (FMEA) – enables companies to reduce the risk of failure occurrence by anticipating and preventing defects in manufacture.

This interactive and practical course will provide delegates with a working knowledge of the FMEA methodology, how to apply it to product and process design, and demonstrates how the results of the FMEA are used to define the requirements for:

  • An effective product validation plan
  • An effective control plan for the manufacturing process

Through the combination of interactive tutorials and workshops, the course will enable the delegates to:

  • Produce an FMEA
  • Fit an FMEA into the overall production process design
  • Communicate why the FMEA should be regularly updated
  • Practical workshops are used to reinforce the discussions and topics
  • Exercise: This will include solution testing including, “Switch the cause on and off” and a mechanism for trialling the proposed solutions

Understanding Statistical Process Control (SPC)

SPC is considered one of the core tools for measuring and controlling performance.  The course is highly interactive with the emphasis being on learning by doing. The training will contain worked examples of SPC.

Course Objectives
This interactive and practical course will provide delegates with a working knowledge of the SPC methodology. By the conclusion of the course delegates will understand:

  • Process Variation
  • Data Collection & Sampling
  • Display & Interpret Data
  • Control Chart Basics
  • Process Stability & Control
  • I-MR Charts
  • Process Capability
  • Using Variable Control Charts X bar-R charts and X bar-s charts
  • Moving average & moving range Charts
  • Checking for trends and option for trend control chart
  • Process Capability Cp/Cpk
  • Attribute SPC
  • Calculation of control limits based on data
  • Green Belt Certificates:

Delegates who have completed this programme based on pre-determined in-company projects will be issued with a 6 Sigma Green Belt Certificate by the Wales Quality Centre.

Training delivery
For this programme to be effective the organisation must select a project on which to base the training, The programme can be delivered effectively for up 8 delegates, consequently, 2 projects would be viable and each project can have a team of up to 3 or 4 members.  At the outset of the programme, the trainer will visit the organisation and agree the nature and complexity of the projects to ensure their viability.   Once the individual projects have been agreed, the project teams will compile their project plans based on DMAIC .  The individual training sessions will focus on applying the subject matter to the projects ensuring a clear understanding of when and how to apply the methodologies.

The project work starts during the principle training sessions – i.e. FMEA, SPC and Global 8D.  Depending on the complexity of the project each team will have a project plan based on DMAIC to continue the exercise to completion.  The trainer will provide ongoing support/mentoring at pre-determined intervals to ensure project milestones and timeliness are maintained.  The amount of time needed after the principle training will vary depending on the nature of the project and the corresponding team’s ability and progress.  The organisation (customer) will dictate the required number of days for support.

On the completion of the projects the team(s) will present the outcome to organisations management team and trainer.  The latter will confirm the conclusion of the projects and sign off of the Green Belt certificates.

Wales Quality Centre Certificates will be provided for this training.
