This unit of competency covers the skills and knowledge required to quantitatively analyse past changes made in an organisation’s operations, systems, process or environment to ensure the quantum of expected change has been achieved and that gains are maintained and are used as a basis for further gains.

The unit includes statistical and other mathematical analysis of data, methods for capturing data on implemented changes (quantitative and qualitative) and producing useful information from this data. It includes consultation with stakeholders both for data validation and consensus decision making for future improvements.

This unit applies to team leaders, technical experts and people with a similar sphere of influence/scope of authority and responsibility who already have a knowledge of statistics used in managing operations and of process capability improvement and some knowledge of factorial design, the selection and analysis of appropriate metrics, and the discrimination between valid and invalid interpretations of data

The unit applies to reviews of both intended and unintended consequences of change and the effectiveness of the implementation of the change. This unit is not intended to be applied to a technical or engineering review of a major capital expenditure or similar.

This unit takes a largely quantitative approach to the review.

This unit may also be applied to service organisations applying competitive systems and practices principles.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include the ability to quantitatively analyse one (1) or more changes and to:

analyse the change

review the results of the change

identify improvements to be made.

Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to analyse a change, including knowledge of:

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, particularly those related to the change

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

range of typical metrics, their applications and limitations

trends, correlation and causation.

The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.

The collection of performance evidence is best done from a report and/or folio of evidence drawn from:

a single project which provides sufficient evidence of the requirements of all the elements and performance criteria

multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.

A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.

Assessment should use an analysis of a real change in an operational workplace.

Knowledge evidence may be collected concurrently with performance evidence or through an independent process such as workbooks, written assessments or interviews (provided a record is kept).

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.

Foundation skills are integral to competent performance of the unit and should not be assessed separately.

Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.

The assessor must demonstrate both technical competency and currency.

Technical competence can be demonstrated through:

relevant VET or other qualification/Statement of Attainment AND/OR

relevant workplace experience

Currency can be demonstrated through:

performing the competency being assessed as part of current employment OR

having consulted with an organisation providing relevant environmental monitoring, management or technology services about performing the competency being assessed within the last twelve months.

This section describes those required skills (language, literacy and numeracy) that are essential to performance.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
