Unit Descriptor
This unit of competency covers the skills and knowledge required to make process capability improvements, including analysing data from the process, developing improvements to eliminate variation due to assignable causes, and then implementing actions.
Application of the Unit
This unit applies to a person who reviews a range of process capability data and information, makes/arranges for changes to be made to procedures, equipment or process and then recalculates the process capability and monitors resulting improvement actions. The person will typically be a technical expert, team leader or be in a role where they have sufficient technical understanding of processes in their own work and that of others to be able to suggest and justify process capability improvements.
Process capability may have been determined using either a six sigma or three sigma processes. This unit applies to the application of statistical methods and the determination of capability based on those methods. Other related units may be MSS404052A Apply statistics to operational processes and MSS404053A Use six sigma techniques
This unit primarily requires the application of skills associated with communication, information gathering and analysis. Initiative, enterprise and problem solving are also required to identify opportunities to improve process capacity. This unit also requires aspects of self-management and learning to validate own analysis.
For a qualitative approach to improvement (one not using statistics) see MSS403051A Mistake proof an operational process.

Required knowledge includes:
|
Evidence Guide
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
|
Context of and specific resources for assessment |
Assessment of performance must be undertaken in a workplace using or implementing one or more competitive systems and practices. Access may be required to:
|
Method of assessment |
A holistic approach should be taken to the assessment. Competence in this unit may be assessed by using a combination of the following to generate evidence:
In all cases it is expected that practical assessment will be combined with targeted questioning to assess underpinning knowledge. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability. |
Guidance information for assessment |
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the candidate and the work being performed. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
|
Competitive systems and practices |
Competitive systems and practices may include, but are not limited to:
Competitive systems and practices should be interpreted so as to take into account:
|
Process capability |
Process capability is:
|
Variation |
All processes have variation. The approach in this unit is to separate random variation (no assignable cause) from non-random variation (which has an assignable cause). By finding and eliminating assignable causes, total variation is reduced and process capability will be improved |
Six sigma |
Six sigma refers to:
|
Three sigma |
Three sigma refers to:
|
Required data |
The calculation of three sigma or six sigma limits requires process data. The data required depends on the nature of the limits being calculated |
Assignable cause |
Any non-random variation is said to have an ‘assignable cause’. The methods of data analysis common to statistical capability analysis as well as other methods of root cause analysis should be used to determine the cause of this non-random variation |
Improved process capability |
Improvements to process capability result from eliminating the causes of non-random variation. The improvements made may be:
|
Procedures |
Procedures may include:
Procedures may be:
