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 will be able to select appropriate strategies, techniques and tools and adapt them to the organisations needs. They will also be able to apply the strategies to new areas and improve their operation in existing areas.

What are the specific resource requirements for this unit?

Access to an organisation using, or about to use, predictive maintenance strategies.

In what context should assessment occur?

Assessment will need to occur in an organisation using, or about to use, a predictive maintenance strategy or a case study or 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 assessed concurrently with other relevant maintenance units and technical units related to the techniques and tools.

This unit is related to:

MSACMT280A Undertake root cause analysis

MSACMT281A Contribute to the application of a proactive maintenance strategy, and

MSACMT481A Undertake proactive maintenance analyses

which cover different aspects/levels of this area.

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?

If evidence is provided from the initial introduction of a predictive maintenance strategy or a significant maintenance strategy, then one development and implementation may provide sufficient evidence. Where evidence is from the ongoing improvements of an existing strategy, then it will be needed from a range of activities to provide sufficient evidence.

Required skills

communication

teamwork

analysis

problem solving

mathematics

planning

reading and interpreting engineering specifications/drawings

computer use

prioritising

recording data

Required knowledge

characteristics and strengths of different types of strategies, techniques and tools such as TPM, RCM, MTBF, FMEA, condition monitoring, RCA

holistic costs of different strategies combining cost of maintenance with costs of lost production, sales etc as relevant to the organisation

business goals sufficient to match the strategy to the business needs

strategic thinking and its application to proactive maintenance

principles of process equipment and how to improve its reliability

resources required and how to obtain them

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 manufacturing

Competitive manufacturing is used to describe the range of systemic manufacturing practice concepts and approaches. It covers but is not limited to:

lean manufacturing

agile manufacturing

preventative and predictive maintenance approaches

monitoring and data gathering systems such as Systems Control and Data Acquisition (SCADA) software, Enterprise Resource Planning (ERP) systems, Manufacturing Resource Planning (MRP), and proprietary systems such as SAP

statistical process control systems, including six sigma and three sigma

Just in Time (JIT), kanban and other pull related manufacturing control systems

supply, value, and demand chain monitoring and analysis

other continuous improvement systems.

Competitive manufacturing should be interpreted so as to take into account the stage of implementation of competitive manufacturing approaches, the enterprise's size and work organisation, culture, regulatory environment and manufacturing sector.

Strategies and techniques

Total Preventative Maintenance/Total Productive Maintenance (TPM) is an application of total quality management to maintenance with the intention of increasing reliability, getting it right first time and increasing Overall Equipment Efficiency (OEE).

Reliability Centred Maintenance (RCM) moves maintenance from reactive, or even planned/programmed towards a focus on uptime and OEE

Root Cause Analysis (RCA). There are many possible causes of any problem. Eliminating some will have no impact, 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.

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

OEE = availability x performance x quality rate

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 losses due to rejects, re-works and start up waste.

Mean Time Between Failure (MBTF) is one key measure of the effectiveness of a maintenance procedure, and is an indicator as to whether root causes are being found and resolved. If MBTF is reducing, then it is an indicator that the maintenance regime is failing.

Failure Mode and Effects Analysis (FMEA) is a systematic approach that identifies potential failure modes in a system, product, or manufacturing/assembly operation caused by either design or manufacturing/assembly process deficiencies. It also identifies critical or significant design or process characteristics that require special controls to prevent or detect failure modes. FMEA is a tool used to prevent problems from occurring.

Some industry sectors have highly adapted forms of FMEA and may practice traditional FMEA in say their routine maintenance while using another technique (such as HAZOP) for design and modification.

Hazard and Operability Studies (HAZOP) is a form of FMEA which has been practiced by the process industries for over 30 years and examines the implications of changes in process conditions to process stability.

Condition monitoring involves often quite sophisticated monitoring of equipment including such things as vibration monitoring, instrumental analysis of lubricating oil etc to determine the current state of the equipment, monitor the change in this condition and predict when it needs servicing/maintenance to maintain reliability.

Tools

Tools selected will vary with the selected strategy and techniques. Tools should be compatible with the strategy and techniques chosen.

This unit does not cover the use of selected tools.

Tools may include root cause analysis, condition monitoring, maintenance/breakdown history, manufacturer's recommendations
