Undertake basic root cause analysis

Assessment tool

Version 1.0
Issue Date: April 2024


In a typical scenario, the employee works in an organisation which is applying competitive manufacturing strategies. This involves the operator in "owning" their process, taking responsibility for it, undertaking basic root cause analysis of problems and generally contributing to increasing the up time and general overall equipment efficiency (OEE). This competency comes from the Competitive Manufacturing Initiative group of competency standards.

This unit describes the performance outcomes, skills and knowledge required to contribute to an advanced maintenance strategy; competitive manufacturers rely on the use of root cause analysis (RCA) by all personnel.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

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

Evidence of the ability to:

the competent operator will be able to recognise problems in their process and undertake a root cause analysis, either alone or with assistance, and propose permanent solutions. Evidence of root cause analyses undertaken should be available

generally a range of RCA activities will be required in order to generate sufficient evidence.

Context of and specific resources for assessment

Assessment must ensure:

assessment will need to occur in an organisation implementing root cause analysis or by simulation or project

access to an organisation using RCA.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICPSU458C Monitor production workflow

ICPSU482C Troubleshoot and optimise materials and machinery.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started

communication of ideas and information by liaising with relevant people to confirm decision

collecting, analysing and organising information by monitoring implementation and making improvements

planning and organising activities by monitoring implementation and making improvements

teamwork when seeking assistance as required according to level of responsibility and personal capabilities

mathematical ideas and techniques by gathering information to eliminate/confirm causes

problem-solving skills by selecting the most appropriate solution based on machinery capabilities, material requirements and job schedules

use of technology by utilising equipment and tools to analyse capabilities

Required knowledge

analysis

problem solving

communication

documenting

root cause analysis methodology

indicators of a problem

principles of the process sufficient to undertake a RCA and propose solutions

use of relevant analysis tools (cause/effect diagrams, Pareto Charts, 4W)

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.

Quick fix may include:

not all situations can wait for the root cause analysis and eventual elimination of the root cause as there are serious current impacts. The quick fix will control these immediate impacts, but does not eliminate the root cause. The quick fix is sometimes referred to as the "quick and dirty" solution.

Root cause may include:

there are many possible causes of any problem. Eliminating some causes will have no impact, eliminating others will ameliorate the problem. However elimination of the root cause will eliminate the problem. There should only be one root cause for any problem and so the analysis should continue until this one cause is found. Elimination of the root cause permanently eliminates the problem.

Cause tree may include:

the series of causes is referred to as the cause tree. Not all root causes are accessible and able to be eliminated. Breaking the cause tree in such a way that the problem cannot recur is an acceptable alternative.

Uptime may include:

uptime refers to the overall availability of the plant - it is the inverse of downtime or the unavailability of the plant. Ideal uptime is 100%.

Overall equipment efficiency (OEE) may include:

the combination of the main factors causing loss of productive capacity from equipment/plant and where:

availability takes into account losses due to breakdown, set up and adjustments

performance takes into account losses due to minor stoppages, reduced speed and idling

quality rate takes into account t losses due to rejects, reworks and start up waste.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
