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 | Review process data | 1.1 | Confirm area of responsibility/study with executive leaders and other stakeholders. |
| 1.2 | Review statistical process control (SPC), process capability and other relevant data for area of responsibility/study. |
| 1.3 | Identify shifts in process performance and processes requiring improvement. |
| 1.4 | Quantify the shifts in performance which have occurred or which are desired. |
| 1.5 | Determine cost of shift in performance and cost of intervention. |
| 1.6 | Identify improvement priorities and degree of intervention. |
|
2 | Apply define, measure, analyse, improve, and control and standardise (DMAIC) process to priority areas | 2.1 | Define improvement project. |
| 2.2 | Determine if a six sigma project team is to be established or project undertaken individually. |
| 2.3 | Determine metrics and acquire initial data. |
| 2.4 | Analyse data and determine possible causes of performance shifts/process improvements. |
| 2.5 | Develop and trial improvement solutions. |
| 2.6 | Control and standardise the improvement. |
|
3 | Establish/review control strategies | 3.1 | Determine sampling schedule. |
| 3.2 | Analyse data to determine process capability. |
| 3.3 | Develop process control strategy. |
| 3.4 | Confirm strategy with all stakeholders. |
| 3.5 | Identify skills required to implement and monitor process control strategy. |
| 3.6 | Arrange training, where required, for employees in skills and techniques needed for process control strategy. |
|
4 | Review and confirm improvement | 4.1 | Calculate and document benefits. |
| 4.2 | Ensure procedures and other relevant documentation is updated for improved procedure. |
| 4.3 | Review process data after an appropriate period and confirm the improvement. |
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 manage six sigma for process control and improvement in the workplace for one (1) or more processes to:
review process data to identify improvement priorities and degree of intervention
apply DMAIC to make and then standardise improvements
collect and analyse data to confirm improvement
determine and review improvements obtained.
Must provide evidence that demonstrates sufficient knowledge to interact with relevant personnel and be able to manage the application of six sigma (or similar), including knowledge of:
identification and definition of six sigma (or similar) projects
sampling, data collection, and analysis
determining quantifiable benefits
DMAIC methodology and application
charting, including Pareto charts, fishbone diagrams, PICK charts, run charts and scatter diagrams
statistical principles and analysis, including confidence limits, analysis of variance, frequency distribution tables, histograms, arithmetic mean, median, mode, standard deviation, range, interquartile range, correlation and dependence
acceptance criteria/confidence levels
failure mode and effects analysis (FMEA)
process mapping
suppliers, inputs, process, outputs, customers (SIPOC) mapping
types of data (e.g. discrete/continuous/attributes) and their use in six sigma.
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:
should occur over a range of situations which include typical disruptions to normal, smooth operation of the workplace
will typically include a third-party (e.g. supervisor, 360 degree) report focussing on consistent performance and problem recognition and solving. A third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
must include either a six sigma project(s) or evidence of day-to-day managing of the application of six sigma in own workplace.
Assessment should occur in operational workplace situations.
Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) 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.
