Elements and Performance Criteria

Uptime refers to the overall availability of the plant - it is the inverse of downtime or the unavailability of the plant. Ideal uptime is 100%.


Overall Equipment Efficiency (OEE) is the combination of the main factors causing loss of productive capacity from equipment/plant and is:

where:

availability takes into account losses due to breakdown, set up and adjustments

performance takes into account losses due to minor stoppages, reduced speed and idling

quality rate takes into account t losses due to rejects, re-works and start up waste.


Procedures include 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, verbal, 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.

Overview of assessment requirements
The employee should 'own' their plant/equipment and take a lead role in ensuring that it is always operating in peak condition and with high and increasing OEE.

What are the specific resource requirements for this unit?
Access to a plant using a proactive maintenance strategy.

What critical aspects of evidence are required to demonstrate competency in this unit?
There should be evidence of deviations recognised and appropriate solutions implemented.

In what context should assessment occur?
Assessment needs to occur in an organisation using a predictive maintenance strategy.

Are there any other units which could or should be assessed with this unit or which relate directly to this unit?
This unit may be assessed concurrently with other units dealing with maintenance.
This unit is related to:
which cover the intermediate and high skill levels respectively.

What method of assessment should apply?
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria, skills and knowledge. A holistic approach should be taken to the assessment.
Assessors should gather sufficient, fair, valid, reliable, authentic and current evidence from a range of sources. Sources of evidence may include direct observation, reports from supervisors, peers and colleagues, project work, samples, organisation records and questioning. Assessment should not require language, literacy or numeracy skills beyond those required for the unit.
The assessee will have access to all techniques, procedures, information, resources and aids which would normally be available in the workplace.
The method of assessment should be discussed and agreed with the assessee prior to the commencement of the assessment.

What evidence is required for demonstration of consistent performance?
Evidence should be required from a range of activities indicating that the maintenance and monitoring elements are a routine part of the job and that the identification of patterns and taking action has occurred in a range of situations.
