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.
Production control related tasks
Production control related tasks covered by this unit may include:
measuring and recording data either manually or using automated data collection
determining process capability indices for a large sample of a product with a particular dimension normally distributed within upper and lower specification limits
applying a range of sampling plans to products or measurable aspects of services and justify the choice of sampling plan based on the properties required of the plan
applying control charts to a sample from a product or service to determine acceptability of the product or service within set limits (e.g.3s and 6s limits)
analysing data for trends and taking corrective action in accordance with procedures
selecting and employing appropriate control charts from c-chart, p-chart and X-bar and R or np control charts
employing a Pareto analysis to determine priority issues for solutions related to a specific problem
Process control
Process control includes the qualitative and quantitative analysis of the process and production data necessary to ensure customer requirement
Required performance indicators for production or service operations
Required performance indicators for production or service operations will vary according to the nature of the product or service and may include:
design features, such as dimensional and weight specifications and tolerances
production schedules
organisation or customer specified target error rates and waste, including those set under lean systems, such as 6s
equipment availability indices
mass balancing targets
WHS related indicators (e.g. lost time injury)
takt time compliance
WHS, regulatory requirements and enterprise procedures

WHS, regulatory requirements and enterprise procedures may include:
WHS Acts and regulations
relevant standards
codes of practice from Australian and overseas engineering and technical associations and societies
risk assessments
registration requirements
safe work practices
state and territory regulatory requirements
Lean principles
Lean principles and techniques use cost, capacity and responsiveness, quality, reliability and waste minimisation as drivers of the process and measures for process improvement.

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
A person who demonstrates competency in this unit must be able to measure and analyse production or service performance data and apply techniques for process control to maintain efficient and effective production or supply or service to customers and to provide data for improvements to enhance competitiveness. This includes working individually and as part of a team in accordance with organisational procedures
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
determine measurable and controllable parameters of product or service,
determine acceptable variation of production or service parameters
use manual and automatic methods for measurement, data gathering and analysis
apply software and control chart techniques for SPC, performance analysis and graphical representations, including generating histograms, Pareto diagrams, flowcharts, tally charts, scatter plots and/or run charts from production or measurable service data
review production and service functions in order to recommend or make process improvements that are based on statistical analyses
identify WHS and regulatory requirements, risk management and related organisational procedures
report and document results.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, then a simulated working environment must be used where the range of conditions reflects realistic workplace situations.
The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
