Leading the application of Six Sigma methodology to a project
Overview
This standard covers the competences required for leading the application of a structured six sigma methodology to a project. It involves leading the identification of the six sigma organisational infrastructure, roles and responsibilities and business-specific metrics that will apply. These will include financial, quality and process aspects of the project. You will be expected to agree areas where the six sigma tools, techniques and activities can be applied, in order to demonstrate those factors that are critical to the customer, business and process.
Contribution to the identification of the cost of poor quality by agreeing the defects per million opportunities (DPMO) is a major part of this standard.
Your responsibilities will require you to comply with organisational policy and procedures for the activities undertaken, and to report any problems with the activities that you cannot solve, or that are outside your responsibility, to the relevant authority. You will need to ensure that all the five phases of six sigma are utilised within the project (such as define, measure, analyse, improve and control), and to ensure all necessary project documentation is completed accurately and legibly. You will be expected to take full responsibility for your own actions within the activity, and for the quality and accuracy of the work that you produce.
Your underpinning knowledge will provide a good understanding of the application six sigma methodology, and will provide an informed approach to the techniques and procedures used. You will need to understand the principles and application of six sigma methodology, in adequate depth to provide a sound basis for carrying out the activities to the required criteria.
Applying and advising on safe working practices will be a key issue throughout.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- lead the application of the structured Six Sigma methodology and approach to the selected project
- approve the Six Sigma organisational infrastructure, roles and responsibilities and business-specific metrics that would apply
- agree areas where the Six Sigma tools, techniques and activities can be applied, and direct the need to measure those factors that are critical to quality characteristic (CTQC) for the customer, business and process
- contribute to the identification of the cost of poor quality, by agreeing the defects per million opportunities (DPMO)
- establish defects per million opportunities to the sigma score, and determine the gap to improve Six Sigma performance
- monitor the progress of the performance
Knowledge and Understanding
You need to know and understand:
- how to work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- the Six Sigma methodology, and how it is applied to a project
- how to plan the resources and time needed to carry out the agreed activity
- the Six Sigma infrastructure and philosophy
- the benefits that will arise from a Six Sigma project
- the 'parts per million opportunities' goal of Six Sigma
- the calculation of defects per million opportunities (DPMO)
- the five phases of Six Sigma that are applied to a project
- how to define a critical to quality characteristic (CTQC)
- how non-value added activity can serve as a roadblock for achieving Zero Defect
- how to define an 'opportunity for defect'
- the roles and responsibilities of the key players in the six sigma process
- the relationship between key process input variables (KPIV) and key process output variables (KPOV) using the equation Y=(f)x
- the extent of your own authority, and to whom you should report in the event of problems that you cannot resolve
Scope/range
Scope Performance
1. Lead the activities within your area of responsibility to include all of the following:
- set out and communicate the purpose of the improvement activities
- involve the team in planning how the improvement activity will be achieved

- provide advice and support the team to achieve both team and individual improvement objectives
- motivate the team to present their own improvement ideas
- encourage the team and/or individuals to take the lead where appropriate
- agree the implementation of the improvement ideas
- negotiate any physical and/or financial resources required to implement the improvement activity (where appropriate)
- monitor the progress of improvement activities
- deal with any organisational problems identified during the improvement activity
