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.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

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.

Guidance information for assessment

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

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started

communication of ideas and information by liaising with relevant staff to facilitate changeover

collecting, analysing and organising information by determining whenchangeover will be required according to production schedule

planning and organising activities by planning a quick changeover according to quick changeover principles

teamwork when working with others to affect a quick changeover

mathematical ideas and techniques by checking output to ensure that it meets specifications

problem-solving skills by identifying actions which may be performed in a more ergonomic manner

use of technology by using required tools/parts/materials for changeover

Required knowledge

principles of quick changeover

relevant procedures

purposes/requirements of changeover

methods of recommending changes

quality requirements for products

minimisation of changeover scrap

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 may include:

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 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 may include:

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 may include:

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 may include:

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.
