Elements and Performance Criteria

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.

Six sigma
A vision of quality which equates to only 3.4 defects per million opportunities for each product or service transaction
Six sigma is a statistical tool for recording defects and determining capability. Six sigma is also used as a general term covering a competitive manufacturing approach

Three sigma
Traditional statistical process control uses three sigma limits which equates to 3 defects per thousand opportunities for each product or service transaction

Procedures
Procedures includes all work instructions, standard operating procedures, formulas / recipes, batch sheets, temporary instructions and similar instructions provided for the smooth running of the plant. They may be written, oral, computer-based or in some other form.
For the purposes of this Training Package, procedures also includes good operating practice as may be defined by industry codes of practice (eg Good Manufacturing Practice (GMP), Responsible Care) and government regulations

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

Evidence of the following is essential:

The manager should be able to implement and review a process capability system and make improvements to the process using process capability as a tool. Evidence should be available of the conducting of process capability studies, the improvement to process capability as a result of these studies and the implementation of a revised process capability regime
One complex project or several simpler projects will be needed to gain sufficient evidence

Context of and specific resources for assessment

Assessment must ensure:

assessment needs to occur in an organisation using process capability as a tool for process monitoring and improvement. It may also be assessed using a suitable project
access to an organisation using process capability

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICPSU583B Troubleshoot and optimise the production process.
