Description
This unit of competency covers the skills and knowledge required to manage six sigma in the workplace for the purposes of process control and process improvement.
Notes
Elements and Performance Criteria
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
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.
Competitive systems and practices

Competitive systems and practices may include, but are not limited to:
lean operations
agile operations
preventative and predictive maintenance approaches
monitoring and data gathering systems, such as Systems Control and Data Acquisition (SCADA) software, Enterprise Resource Planning (ERP) systems, Materials Resource Planning (MRP) and proprietary systems
statistical process control systems, including six sigma and three sigma
Just in Time (JIT), kanban and other pull-related operations control systems
supply, value, and demand chain monitoring and analysis
5S
continuous improvement (kaizen)
breakthrough improvement (kaizen blitz)
cause/effect diagrams
overall equipment effectiveness (OEE)
takt time
process mapping
problem solving
run charts
standard procedures
current reality tree
Competitive systems and practices should be interpreted so as to take into account:
the stage of implementation of competitive systems and practices
the size of the enterprise
the work organisation, culture, regulatory environment and the industry sector
DMAIC
DMAIC is a structured improvement methodology for existing business processes involving the following stages:
define
measure
analyse
improve
control and standardise
Define
Definition of the project to include:
completed, verified and validated as in process map
SIPOC diagram
discrepancies to current 'as is' process map
formation and briefing of project team
defining business case for project
problem statement
goal statement
project scope
Metrics
Metrics may include:
key measures/attributes
sampling schedule for project
defect rate
Analyse
Analyse may include:
statistical analysis of data
root cause analysis
FMEA
use of various other problem solving/analysis tools
Improve
Improve may include:
generating and testing of improvements
selecting appropriate improvements
Control and standardise
Control and standardise may include:
documenting outcomes and procedures for standardisation
transferring ownership of improved process
Sampling schedule
Sampling schedule may include:
sampling frequency
type of sample/sample method
sample location/type
type of test/data to be collected
Process control strategy
Process control strategy may include:
degree of intervention/rules for resets
SPC tools to be used
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.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
analyse statistical data and identify significant variations and other indicators for potential six sigma projects
apply DMAIC process individually
lead others in DMAIC process
review control strategies
confirm improvements.
Context of and specific resources for assessment
Assessment of performance must be undertaken in a workplace using or implementing one or more competitive systems and practices.
Access may be required to:
workplace procedures and plans relevant to work area
specifications and documentation relating to planned, currently being implemented, or implemented changes to work processes and procedures relevant to the assessee
documentation and information in relation to production, waste, overheads and hazard control/management
reports from supervisors/managers
case studies and scenarios to assess responses to contingencies.
Method of assessment
A holistic approach should be taken to the assessment.
Competence in this unit may be assessed by using a combination of the following to generate evidence:
demonstration in the workplace
workplace projects
suitable simulation
case studies/scenarios (particularly for assessment of contingencies, improvement scenarios, and so on)
targeted questioning
reports from supervisors, peers and colleagues (third-party reports)
portfolio of evidence.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess underpinning knowledge.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the candidate and the work being performed.
