Elements and Performance Criteria

1. Obtain data for process capability study
   • Identify the process requiring capability analysis
   • Obtain process capability data
2. Analyse data
   • Identify assignable causes of variation in liaison with relevant personnel
   • Develop solutions to eliminate variation due to assignable causes in liaison with relevant people
   • Analyse random variations for possible causes in liaison with relevant people
   • Confirm cause/s of random variation
   • Develop solutions to reduce random variations in liaison with relevant people
3. Take action to improve process capability
   • Develop plans to implement solutions
   • Liaise with relevant people to implement solutions
   • Gain necessary approvals as required
   • Monitor implementation and make adjustments as required
   • Determine new/revised process capability
   • Implement revised process capability regime

Required Skills

Required skills

mathematical statistical methods communication negotiation planning analysis problem solving teamwork computer operation

Required knowledge

data collection methods data processing techniques required variability and normal distribution three sigma or six sigma processes as relevant random and nonrandom results recognition of assignable causes causes of different types of nonrandom results causes of random variation process understanding sufficient to translate the data into variations in the process and determine methods of controlling them

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge the range statement and the assessment guidelines for this training package
Overview of assessment requirements	The person should be able to implement and review a process capability system and make improvements to the process using process capability as a tool
What are the specific resource requirements for this unit	Access to an organisation using process capability
In what context should assessment occur	Assessment needs to occur in an organisation using process capability as a tool for process monitoring and improvement It may also be assessed 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 is related to MSACMTA Monitor process capability and MSACMT250A Monitor process capability, and MSACMTA Undertake process capability improvements MSACMT450A Undertake process capability improvements which cover the lowest and intermediate skill levels in CM respectively
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	One complex project or several simpler projects will be needed to gain sufficient evidence

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.
Six sigma	Six sigma is a statistical tool for recording defects and determining capability which equates to only 3.4 defects per million opportunities for each product or service transaction. Six sigma is also used as a general term covering a competitive manufacturing approach. Six sigma training typically covers several units of competency in this Training Package.
Three sigma	Traditional statistical process control uses three sigma limits which equates to 3 defects per thousand opportunities for each product or service transaction.
Procedures	Procedures includes all work instructions, standard operating procedures, formulas/recipes, batch sheets, temporary instructions and similar instructions provided for the smooth running 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 (eg Good Manufacturing Practice (GMP), Responsible Care) and government regulations.
