Description
This unit describes the skills and knowledge required to design experiments to confirm viability of process improvements. This unit applies to technical experts and similar roles who are required to identify areas for significant or breakthrough improvement and use statistical methods to design and run experiments and confirm results. This unit applies to any organisation. No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
Notes
Elements and Performance Criteria
1. Choose an improvement project
  • 1.1 Review process or value stream map to identify areas in need of improvement
  • 1.2 Select rea of process or value stream for analysis and improvement
  • 1.3 Consult with relevant stakeholders to determine objective of experiment
2. Design the experiment
  • 2.1 Select factorial design appropriate to objective of experiment
  • 2.2 Estimate signal to noise ratio
  • 2.3 Determine required number of runs and factorial fraction
  • 2.4 Determine resolution
  • 2.5 Design sequential series of experiments
  • 2.6 Calculate resource requirement for this design
  • 2.7 Consult with relevant stakeholders to determine whether resource requirements are practical and/or feasible
  • 2.8 Modify experiment, if required, to match available resources
  • 2.9 Determine metrics relevant to experiment objective and design
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 or oversee recording of data to meet requirements of experiment
4. Analyse and confirm the experimental results
  • 4.1 Identify aliases and confounding of variables and/or results
  • 4.2 Analyse data using statistics pack
  • 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 confirming experiments
