Description
This unit of competency covers the skills and knowledge required to design experiments. The design of experiments is generally undertaken as part of black-belt six sigma but may also be undertaken independently.This unit applies to a technical expert who is required to design and implement experiments aimed at making breakthrough improvements in the process. They will work with other members of the process team in doing this.This unit primarily requires the application of skills associated with problem solving, initiative and enterprise, and planning and organising skills in order to identify, implement and evaluate an experiment. Communication skills associated with gathering, interpreting and documenting information are required.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Choose an improvement project
  • 1.1 Review a process/value stream map.
  • 1.2 Identify areas in need of improvement.
  • 1.3 Select a process/value stream area for analysis and improvement.
  • 1.4 Determine the objective of the experiment in consultation with relevant stakeholders.
2 Design the experiment
  • 2.1 Select appropriate factorial design.
  • 2.2 Estimate signal to noise ratio.
  • 2.3 Determine required number of runs and factorial fraction.
  • 2.4 Determine resolution.
  • 2.5 Design a sequential series of experiments.
  • 2.6 Calculate resource requirement for this design.
  • 2.7 Determine whether resource requirements are practical in consultation with relevant stakeholders.
  • 2.8 Modify experiment, if required, to match available resources.
  • 2.9 Determine/develop required metrics.
3 Conduct the experiment
  • 3.1 Conduct first run of experiment.
  • 3.2 Replicate in random order for required number of runs.
  • 3.3 Block out known sources of variation.
  • 3.4 Conduct other experiments in series.
  • 3.5 Record data/have data recorded.
4 Analyse and confirm the experimental results
  • 4.1 Identify aliases/confounding of variables/results.
  • 4.2 Analyse data using statistics pack or similar.
  • 4.3 Interpret analysed data in line with objectives.
  • 4.4 Identify confidence level of analysed data.
  • 4.5 Design experiment to confirm correlations identified.
  • 4.6 Conduct confirming experiment.
  • 4.7 Analyse data from confirming experiment.
  • 4.8 Confirm results (or conduct further experiments).
