Elements of Competency and Performance Criteria



1.   Prepare required customer requirements from information provided

  1. Criteria for the engineering application are obtained in accordance with standard operating procedures.

2.   Verify that customer requirements have been met in the engineering application criteria

  1. Criteria for the engineering application criteria are reviewed against customer requirement and deficiencies are noted.
  2. Knowledge of engineering parameters is applied to evaluate the engineering application criteria.
  3. Use of appropriate and relevant standards and codes is verified using standard operating procedures or reference to supervisor.

3.   Verify specifications in accordance with economic principles

  1. The relationships between quality, cost of production and function are considered and specifications are verified in accordance with policy and procedures.

4.   Verify specifications in accordance with ergonomic  principles

  1. The specifications are checked and verified for health effects of human/machine interaction in accordance with given policy and procedures.

5.   Seek approval of recommendations

  1. All recommendations are referred to a supervisor for approval in accordance with policy and procedures.

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

  • engineering parameters:
    • safety of personnel, consequences of failure (such as human injury)
    • quality of product consideration
    • material reliability and choice
    • safety factors
    • maintenance, source of spares/service

  • aesthetics

Delivery Plan

The following is a suggested sequence for development of the knowledge and skills relating to this unit of competency.  However, individual institutes and colleges may prefer to develop and use delivery plans of their own. 

1. Design Philosophy

Reliability - statistical (material, consequences of failure, human injury etc)
Design factor, design load and component failure relationships
Design Factor = Failure Load/Design Load
Consideration of factors including:
- Safety of personnel
- Economic consideration
- Material reliability and choice
- Design life
- Proof of design
- Innovation of design
- Efficiency improvement
- Maintenance

2. Design Specification

Design life/criteria
Weight/power ratios
Energy consumption
Production cost
Surface treatment
Duty cycle

3. Economic Considerations

Production quantities (mass/batch)
Cost of manufacture
Cost of maintenance
Quality of product consideration
Practicability of manufacture
Standardised components.

4. Ergonomic

Human capacity: reach, dexterity, strength, repetitiveness, human comfort
Health effects of human/machine interaction.


Range Statement

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.

Engineering application

For this unit, engineering application includes assisting in engineering processes and applications requiring ergonomic and economic knowledge and skills including design, engineering assessments, supervision of installation and commissioning etc.

Engineering parameters

Includes consideration of safety of personnel, consequences of failure (human injury etc.), economic considerations, production cost, quality of product consideration, material reliability and choice, design safety factors, maintenance, energy consumption, source of spares/service

Standards and codes

Includes access and use of Australian standards (AS): AS 3000, AS 1250, AS 4800, AS 1100, International Standards Organisation (ISO) standards

AS 3000: Wiring Rules

AS 1250: Steel Structures

AS 4801: OH&S (being phased out)

AS 1100: Technical drawing

Economic principles

Includes production quantities (mass/batch), cost of manufacture, ease of manufacture, use of standardised components, human capacity (reach, dexterity, strength, repetitiveness, human comfort), aesthetics, health effects of human/machine interaction, safety (Oops: Most of this belongs under Ergonomics. If only we could get our trusty team at the National Training package MEM05 to read some their own units, such as MEM15003B Use improvement processes in team activities.)

Ergonomic principles

Includes designing, installing or checking things for effective human use, and creating environments that are suitable for human living and work. It includes work methods, equipment, facilities, and tools that influence the worker's motivation, fatigue, likelihood of sustaining an occupational injury or illness, and productivity...
