Elements and Performance Criteria

1. Analyse process
   • Identify sources of variability/non-conformance in the process
   • Identify critical control points in process
   • Analyse causes of variability/non-conformance

Required Skills

Required skills

Required skills include communicating with team or work group members technical support personnel and other relevant staff explaining mistake proofing and related concepts facilitating input of others and encouraging acceptance of changes analysing and visualising operations in terms of flow and contribution to customer outcomes solving problems to determine root cause of errors and possible solutions analysing and interpreting information about errors and mistake proofing options in terms of cost feasibility regulations and value to the customer suggesting design changes to operations and products that eliminate the potential for errors suggesting mechanisms or procedures that warn of errors where operations cannot be designed to eliminate errors

Required knowledge

Required knowledge includes mistake proofing concepts including in priority order eliminate the possibility of the error via changes to the process prevent the error from occurring via physical or virtual barriers reduce likelihood of the error by encouraging correct action mitigate the impact of the error if it does occur understanding of processes undertaken by team factors in the processes which may cause variability methods of controlling the variability in the process mistake proofing methods relevant to the processproduct

Evidence Required

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 variability and nonconformances identify analyse and evaluate information from a variety of sources to identify errors and options for mistake proofing facilitate implementation of mistake proofing activities that reduce waste facilitate sustaining the mistake proofing activities
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 controlmanagement reports from supervisorsmanagers 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 studiesscenarios particularly for assessment of contingencies improvement scenarios and so on targeted questioning reports from supervisors peers and colleagues thirdparty 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

Range Statement

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
Mistake proofing	Mistake proofing is based on the concept of zero defects. The first priority is to eliminate the possibility of an error occurring. However, where this is not feasible mistake proofing can be used to reduce the occurrence of errors and/or to minimise their impact. Mistake proofing should target an error in the following priority order: eliminate the possibility of the error via changes to the process prevent the error from occurring via physical or virtual barriers, reduce likelihood of the error by encouraging correct action (e.g. through warning systems) mitigate the impact of the error if it does occur Mistake proofing is also called error proofing or baka-yoke or poka-yoke
Options for mistake proofing	Factors to consider when prioritising options for mistake proofing will vary according to the process and may include: success rate in eliminating errors feasibility skills required by employees cost capacity to reduce waste
Procedures	Procedures may include: all work instructions standard operating procedures formulas/recipes batch sheet temporary instructions and similar instructions provided for the operation of the plant good operating practice as may be defined by industry codes of practice (e.g. good manufacturing practice (GMP) and responsible care) government regulations Procedures may be: written, verbal, computer-based or in some other format
