Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

  5. Optimum target mean to suit process capability data is determined.
  6. Reports listing various options from process capability studies are prepared.
  7. Design specifications based on an analysis of data are recommended.

Instructions to Assessors

Evidence Guide

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.

Overview of assessment

A person who demonstrates competency in this unit must be able to conduct product and/or process capability studies. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with conducting product and/or process capability studies or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

collecting and collating data

analysing data, identifying solutions and developing recommendations

preparing reports listing the various options identified from the process capability study

determining process design specifications from process capability data

documenting sampling plan and implementation strategy

Required knowledge

Look for evidence that confirms knowledge of:

the process to be studied

the procedures for conducting process capability studies

the data used to calculate the process capability

the procedures for estimating the possible number of product defects

options for improving the process and benefits of each

the procedures for determining the optimum target mean

the procedures for setting control limits

numerical operations and calculations/formulae for process capability, control limits and other outcomes within the scope of this unit

the procedures for setting warning limits

the concept of 'out of control' situations

the action to be taken when an 'out of control' situation is detected

the procedures for documenting 'out of control' situations

the acceptable level of quality

a variety of sampling plans and their application

the sampling plan to be applied to a given situation

the reasons for selecting the chosen plan

the acceptable quality limits

the risks associated with identifying acceptable quality limits for the producer and customer

the procedures for documenting and implementing sampling plans

hazards and control measures

use and application of personal protective equipment

safe work practices and procedures

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.

Procedure

Frequency of sample, sample size

Data

From periodic samples drawn from a trial run of the process

Process capability

The natural tolerance of the process which may be calculated at 3 sigma/standard deviations

Product defects

From a consideration of 3 or 6 sigma standard deviations compared to specification requirements etc.

Various options

Adjustment of process to move average; improvements to reduce process capability; changes to reduce assignable causes

Appropriate sampling plan

Plans within the adopted quality system, sample size, frequency of sample etc.
