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.

Changeover
Changeover may refer to an exchange of dies / tools (traditional), or a change between batches, or it may be any quantum equipment / process change to produce a different product eg plate changeover, stock change
This unit may not be applicable to a totally continuous operation producing only the one product or simultaneous range of products. This is not applicable to a maintenance / PVI shutdown as experienced by continuous process manufacturers

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

SMED
Changeover is sometimes referred to as SMED which is a more extreme form where SMED is an abbreviation for Single Minute Exchange of Die; literally, changing a die on a forming or stamping machine in a minute or less; broadly, the ability to perform any set up activity in a minute or less of machine or process downtime. The key to doing this is frequently the capability to convert internal set up time to external set up time. Variations on SMED include:
Single-digit set up: performing a set up activity in a single-digit number of minutes, ie fewer than ten
OTED: One touch exchange of die; literally, changing a die with one physical motion such as pushing a button; broadly, an extremely simple procedure for performing a set up activity

Set up time
Set up time - work required to change over a machine or process from one item or operation to the next item or operation. It can be divided into two types:
internal set up work that can be done only when the machine or process is not actively engaged in production; OR
external set up work that can be done concurrently with the machine or process performing production duties

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:

Routine positive participation in quick changeover procedures
Assessment will need to occur in an organisation using quick changeover or a suitable simulation in say a workshop

Context of and specific resources for assessment

Assessment must ensure:

assessment may take place on the job, off the job or a combination of these. Off the job assessment must be undertaken in a closely simulated workplace environment
machinery for changeover

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.
