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

Demonstrates skills and knowledge required to:

analyse process changes.

In particular look for evidence of:

identification of changes

data and information gathering over a period and range that will provide a valid basis for analysis

selection and use of appropriate data analysis tools

presentation of information in a suitable form

obtaining a consensus view of the results of the change

determining the lessons to be learned and future improvements to be undertaken.

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

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 Manufacturing 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 its 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 able not only 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.

Required skills

decision making

communication at all levels

interviewing skills

statistics/mathematics

situation analysis

Required knowledge

competitive manufacturing principles

organisational goals and processes

continuous improvement and the workplace improvement processes and procedures

statistical process control (SPC) and principles

methods of determining the impact of a change using quantitative analysis of process data, including advanced statistical/mathematical analysis and basic qualitative techniques

organisation metrics

sources of data (actual and possible) within the organisation and the value chain

range of typical metrics, their applications and limitations

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.

Codes of practice/standards

Where changes include areas covered by industry codes of practice, and/or Australian/international standards, the latest version must be used

Gather prior data

Where all suitable data was not collected prior to the change a suitable proxy will be needed

Health, safety and environment (HSE)

All changes implemented are expected to be at least neutral, or preferably beneficial, in their impact on health, safety and environment

Change

Changes may:

be to plant, procedures or practice

arise from continuous improvement (or an improvement event/project) or implementing new products, technology or systems

may have been intended to make an improvement or to implement new products, technology or systems

include the implementation of a change

Changes do not include an engineering review of a major capital expenditure or similar review

Initiation of change

Changes need to be identified as either:

deliberately or not deliberately initiated

Where a change was not deliberately initiated then the causal factors for the change need to be identified

Correlated metrics

Any metric which appears to show a chronological correlation with the change being analysed. These metrics need to be examined to determine if the change has a causal relationship or is simply coincidental

Presentation of information

Information may be presented:

in terms of graphs (or other appropriate visual forms)

verbally or other forms able to be understood and used by stakeholders

Stakeholders

Stakeholders include:

work team members, value chain members, as well as other stakeholders

Results of change

The change results may include:

an initial improvement followed by a return to previous performance

continued improvement

continued detriment or other variations over time

Improvements

Improvements may:

be to process, plant, procedures or practice

include changes to ensure positive benefits are maintained

Sustaining improvement

Improvement may be sustained by including it in:

standard procedures and work instructions

standard practice

other relevant documents and practices

Team leader

Team leader may include:

any person who may have either a permanent or an ad hoc role in facilitating the function of a team in a workplace
