Unit of competency

Modification History

Release 1. Supersedes and is equivalent to MSS404052A Apply statistics to operational processes

Application

This unit covers the ability to gather and analyse process data to support the control of processes and operations. It includes interpretation of sampling procedures, frequency distributions, random and non-random variations in data/control charts; use of control limits to determine whether or not monitored processes are in control; and communicating this information to others.

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.

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.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to MSS404052A Apply statistics to operational processes

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment and must include on two (2) or more occasions:

• gathering, analysing and interpreting process data to support the control of processes and operations
• applying specified sampling procedures
• investigating the causes of variation in a process
• communicating with other employees to obtain samples/data and to explain results and limits
• calculating and plotting data and control limits
• completing other required documentation.

Knowledge Evidence

Must provide evidence that demonstrates knowledge relevant to their job role sufficient to fulfil their job role independently, including:

• purpose of sampling and measurement
• sampling methods to be used
• methods of calculating means, standard deviations and the like and their purpose in statistical control
• concept of limits, including 1, 2, 3 and 6 sigma limits
• types of control charts and their applications to different types of process/product and for different purposes
• process causes of variation and typical cause types of non-random variation
• non-process (e.g. measurement) causes of variation
• recognition of stable and unstable processes
• causes of stability/instability in the process
• calculation of control limits/process capability and the applications of different control limits
• the standard distribution curve and confidence limits.

Assessment Conditions

• The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
• The collection of performance evidence:

• should occur over a range of situations which include typical disruptions to normal, smooth operation of the workplace
• will typically include a supervisor/third-party report focussing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
• must include the application of statistics to an operational process in own workplace
• will typically include the use of appropriate tools, equipment and safety gear requiring demonstration of preparation, operation, completion and responding to problems.

• Assessment should occur in operational workplace situations.
• Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process such as workbooks, written assessments or interviews (provided a record is kept).
• Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
• Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
• Foundation skills are integral to competent performance of the unit and should not be assessed separately.
• Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
• The assessor must demonstrate both technical competency and currency.
• Technical competence can be demonstrated through:

• relevant VET or other qualification/Statement of Attainment AND/OR
• relevant workplace experience

• Currency can be demonstrated through:

• performing the competency being assessed as part of current employment OR
• having consulted with an organisation providing relevant environmental monitoring, management or technology services about performing the competency being assessed within the last twelve months.
