Description
This unit covers the knowledge and skills needed to make changes which prevent errors and/or backsliding to a pre-improvement level of practice. In the CM environment, this unit would typically be done by a team leader, technical expert of similar person.
Notes
Elements and Performance Criteria
1. Analyse process
- 1.1. Identify sources of variability/non-conformance in the process1.2. Identify critical control points in process1.3. Analyse causes of variability/non-conformance
2. Develop preventative techniques/systems
- 2.1. Liaise with team members and other people to develop mistake proof method of performing operation2.2. Test and validate mistake proofing
3. Implement permanent fix
- 3.1. Liaise with relevant people to have systems/procedures changed to implement solution3.2. Liaise with relevant people to implement the solution3.3. Liaise with relevant people to ensure the workforce has an appropriate skills set3.4. Follow through to ensure implementation occurs
4. Monitor implementation
- 4.1. Critically observe the implementation4.2. Compare the results of the implementation against the expected outcomes4.3. Modify solution to improve outcomes4.4. Ensure procedures reflect change4.5. Ensure training/assessment reflects change4.6. Audit change at agreed period/cycle4.7. Take action on any observed deviation
5. Seek improvements
- 5.1. Observe changes5.2. Analyse process again if required to ensure improvements are sustained
Sometimes known as baka-yoke/poka-yoke, a manufacturing technique of preventing mistakes by designing the manufacturing process, equipment, tools and components/subassemblies etc so that an operation literally cannot be performed incorrectly. An attempt to perform incorrectly, as well as being prevented, is usually met with a warning signal of some sort.
Procedures include all work instructions, standard operating procedures, formulas/recipes, batch sheets, temporary instructions and similar instructions provided for the operation of the plant. They may be written, verbal, computer based or in some other form.
For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (e.g. Good Manufacturing Practice (GMP), Responsible Care) and government regulations.
Overview of assessment requirements
The person will be able to analyse their process and implement systems to ensure the process is mistake proof and the operators, work in a predictable way with little or no chance of mistake.
What critical aspects of evidence are required to demonstrate competency in this unit?
Evidence of actions taken to mistake proof the process should be available.
In what context should assessment occur?
Assessment needs to occur in a workplace implementing competitive manufacturing or by using a suitable project.
Are there any other units which could or should be assessed with this unit or which relate directly to this unit?
This unit may be used as a stand alone unit or it may be assessed concurrently with any of:
What method of assessment should apply?
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the elements, performance criteria, skills and knowledge. A holistic approach should be taken to the assessment.
Assessors should gather sufficient, fair, valid, reliable, authentic and current evidence from a range of sources. Sources of evidence may include direct observation, reports from supervisors, peers and colleagues, project work, samples, organisation records and questioning. Assessment should not require language, literacy or numeracy skills beyond those required for the unit.
The assessee will have access to all techniques, procedures, information, resources and aids which would normally be available in the workplace.
The method of assessment should be discussed and agreed with the assessee prior to the commencement of the assessment.
What evidence is required for demonstration of consistent performance?
Where evidence is from the application of
What are the specific resource requirements for this unit?
Access to an organisation using a competitive manufacturing approach.
