Unit of competency
Modification History
Release 2. Updated pre-requisite code
Release 1. Supersedes and is equivalent to MSS405052A Design an experiment
Application
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.
