Modification History
New unit, superseding MSACMT452A Apply statistics to processes in manufacturing - Equivalent
Unit Descriptor
This unit of competency covers the skills and knowledge required to apply statistical theory and principles to the analysis and control of processes and operations.
Application of the Unit
This unit applies to a person working in an organisation applying statistical process control on processes or operations. The statistical process control will usually be used to monitor the processes or operations and determine when action needs to be taken. The appropriate action will then be taken in accordance with standard procedures.
The unit includes applying knowledge of frequency distribution and variation to the data/chart to distinguish between random and non-random variation and assumes understanding of the process and/or equipment to help interpret those results.
This unit primarily requires the application of skills associated with gathering and analysing data and communicating statistical information to others. This unit also has a strong emphasis on problem solving, initiative and enterprise, planning and organising, and self-management to solve problems and manage processes.

Elements and Performance Criteria Pre-Content
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |

|
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:
|
|
Sampling scheme |
Sampling scheme may include:
|
|
Procedures |
Procedures may include:
Procedures may be:
|
|
Handle data |
Handle data may include:
|
|
Control chart |
Control charts may include:
|
|
Random |
Random variation is the term used in statistical control to refer to those variations for which no cause can be found |
|
Non-random |
Non-random (also called identifiable cause, assignable cause or special cause) are those variations for which a cause can be found and so the cause of the variation eliminated. Non-random variation may also be used to predict possible breaches of the control limits |
|
Control limits |
Control limits (also referred to as process capability) are those limits within which the process will operate if it is 'under control' |
|
Cost of non-conformance |
Cost of non-conformance includes:
|
|
Appropriate limits |
Appropriate limits may include:
