List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Obtain data for process capability study | 1.1 | Identify the process requiring capability analysis, including relevant procedures. |
| 1.2 | Identify customer specifications for product or service. |
| 1.3 | Obtain process capability data. |
|
2 | Analyse data | 2.1 | Identify assignable causes of variation in liaison with relevant personnel. |
| 2.2 | Develop solutions to eliminate variation due to assignable causes in liaison with relevant personnel. |
| 2.3 | Analyse random variations for possible causes in liaison with relevant personnel. |
| 2.4 | Confirm causes of random variation. |
| 2.5 | Develop solutions to reduce random variations in liaison with relevant personnel. |
|
3 | Take action to improve process capability | 3.1 | Develop plans to implement solutions. |
| 3.2 | Liaise with relevant personnel to implement solutions. |
| 3.3 | Gain necessary approvals, as required. |
| 3.4 | Monitor implementation and make adjustments, as required. |
| 3.5 | Determine new/revised process capability. |
| 3.6 | Implement revised process capability regime. |
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 determine and improve the capability of one (1) or more processes and to:
obtain relevant data
analyse the data to determine random and non-random variation
develop solutions to reduce variation
develop and monitor the implementation of plans aimed at reducing variation
make further improvements as appropriate and determine capability of improved process.
Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to determine and improve capability, including knowledge of:
statistical methods of processing and describing data
data collection methods
data processing techniques required to establish variability and normal distribution
calculate three sigma or six sigma process capability, as relevant
random and non-random results and processes for recognition of assignable causes
causes of different types of non-random results
causes of random variation
process understanding sufficient to translate the data into variations in the process and determine methods of controlling them.
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 a real capability analysis and improvement project for 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.
