In a typical scenario, a senior technician or para-professional investigates a plant unit/part of the process which is not performing as well as it has/as expected. They methodically investigate this technical problem, come to a conclusion as to the cause and then initiate appropriate corrective action. The corrective action may well be beyond the scope of competency and responsibility of the person to implement. This unit applies to problems which are not solvable by direct observation and require systematic investigation:

damage to/wear of tower trays

internal leaks of heat exchangers

collapse of/channelling in tower/column/vessel packing

The technician would:

clarify the problem

analyse problem cause(s)

recommend a solution to the problem.

Generally the technician would work alone for this unit, although the ability to communicate with all internal and external stakeholders is vital.

2. Define the problem.

2.1. Apply problem isolation techniques to isolate problem to a small part of the plant/process

2.2. Quantify the effect of the problem in operational terms

2.3. Postulate possible causes of the problem

2.4. Identify types of evidence for each possible cause

2.5. Investigate problem to accumulate evidence of cause type

2.6. Analyse data to confirm cause of problem

2.7. Determine the level of severity of the problem, priority of any required action.

3. Develop solution.

3.1. Discuss possible solutions to cause with relevant people

This describes the essential skills and knowledge and their level, required for this unit.

Required skills

This unit requires skills of:

analysis

problem solving

negotiation

communication

basic mathematics

Required knowledge

Competence includes a deep understanding of:

plant equipment, its characteristics and limitations

impact of variations in plant/process and the distinctive signs of each variation

process chemistry, physics and biochemistry as relevant, eg to the extent of writing chemical equations and identifying factors controlling reaction rate and yield or equivalent

problem isolation techniques

problem analysis techniques

organisation approval processes

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 the Training Package.

Overview of assessment

Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which will include a range of problems, problem causes and environments.

Simulation may be required to allow for assessment of parts of this unit. Simulation should be based on the actual problems and should include the use of case studies/scenarios and role plays.

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of what-if scenarios.

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

Competence must be demonstrated in the ability to define and analyse the problem as well as deal with the stakeholders. The stakeholders should be satisfied with the solution, as well as the solution being technically sound.

Consistent performance should be demonstrated. In particular look to see that:

different types of problems can be analysed and resolved

different types of stakeholders can be satisfied

the range of possible causes can be identified and analysed and the most likely cause determined

appropriate action is taken.

These aspects may be best assessed using a range of scenarios/case studies/what-ifs. These assessment activities should include a range of problems, including new, unusual and improbable situations which may have been generated from the past history and similar sources.

Context of and specific resources for assessment

Assessment will require a suitable method of gathering evidence of problem solving ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

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. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

This unit of competency includes problems in the plant, plant equipment or process which may make itself evident through lower quality, lower rates, greater variability or greater difficulty in control.

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
