Elements and Performance Criteria

Waste (also known as muda in the Toyota Production System and its derivatives) is any activity which does not contribute to customer benefit/features in the product.

Within manufacturing, categories of waste include:

excess production and early production

delays

movement and transport

poor process design

inventory

inefficient performance of a process

making defective items.

Waste for this unit may include activities which do not yield any benefit to the organisation or any benefit to the organisations customers.


Necessary waste is any activity or cost which does not contribute directly to customer benefit/feature in the product, and which


Unnecessary waste is any activity or cost which does not contribute directly to customer benefit/features in the product and


Energy is used to mean all sources of energy used by the process be it electricity, gas or mobile transport fuel. The uses of the energy will also be potentially wide and include heating and cooling, moving materials (including pumps and conveyors), modifying materials (including cutting, forming, weaving, knitting, reacting, moulding, extruding, mixing), generating pressure/vacuum or providing motive power for equipment and transport.

Overview of assessment requirements
The person will be able to analyse the energy use of any/all part/s of the process and determine if there are more efficient/cheaper ways of achieving the same result.

What critical aspects of evidence are required to demonstrate competency in this unit?
Evidence of analyses of energy consumed and improvements made should be available.

In what context should assessment occur?
Assessment needs to be conducted in an organisation where energy is a significant cost component or by project, simulation or case study.

Are there any other units which could or should be assessed with this unit or which relate directly to this unit?
This unit is related to:

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?
If evidence is from a major project to improve energy efficiency, then it may provide sufficient evidence. If evidence is from a number of minor improvements to energy then a range of such improvements will be needed to provide sufficient evidence.
