Systems thinking

Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain
Continuous improvement
Continuous improvement implementation may relate to plant, products, processes, systems or services, including design, development, implementation or manufacture, commissioning, operation or delivery and maintenance.
Improvement processes may include techniques, such as:
balanced scorecard
current and future state mapping
measuring performance against benchmarks
process improvement, problem solving and decision making
data management, generation, recording, analysing, storing and use of software
training for improvement systems participation
technical training
Constraints and contingencies
Constraints and contingencies may be:
financial
organisational, procedural or cultural
physical constraints, such as limits to resources, limits to site access or logistical limitations
Maintenance systems
Maintenance systems include:
breakdown maintenance
preventive maintenance
predictive maintenance (on-condition)
precision maintenance
proactive maintenance
reliability centred maintenance
total productive maintenance
Lean systems maintenance

Lean maintenance systems aim at maximising machine and process up-time, minimising waste and costs, maintaining quality and delivery and customer service. Maintenance processes and procedures are subject to continuous improvement and are set to complement engineering business objectives
Integrated maintenance management systems (terotechnology)
Terotechnology is an integrated maintenance management system combining management, financial, engineering and other practices for cost-effective maintenance of assets, such as plant, equipment and facilities. It involves the design for reliability and maintainability, manufacture, installation, commissioning and eventual write-off and replacement of the assets. Data is collected and analysed to assess the reliability, life cycle costs and productivity of the assets against the design criteria.
Reliability relates to the productivity of assets, that is, the maintenance of service or product output (quantities) and its quality within cost parameters. In the context of terotechnology, the cost parameters include life cycle costs
Integrated logistic support (ILS)
ILS is the management and technical process through which supportability and logistic support considerations are integrated into the design and taken into account throughout the life cycle of systems/equipment and by which all elements of logistic support are planned, acquired, tested, and provided in a timely and cost-effective manner. Maintenance systems and schedules are part of this process
Maintenance priority
Assets may be prioritised for maintenance according to different criteria and categories, such as:
critical assets:
high cost of replacement
unavailability of replacement or spares
failure will or may immediately endanger life and property
essential to quality
high cost of disruption to production or service delivery
failure would require an immediate response
semi-critical assets:
shutdown produces partial loss of capacity
assett is regulated
difficult to repair
alternative asset may be available
some spare parts are stored
medium priority for response
non-critical:
breakdown affects minimal production loss
asset used infrequently
parts readily available
lowest priority attended to as time and resources allow
Maintenance activity audit
An audit of plant, facilities and services may be used to identify maintenance requirements with details listed in the maintenance database according to different criteria, such as:
criticality, locality, machine type and maintenance activities required
skills and techniques required for corrective actions
sources and availability of spares
specialised corrective skills and techniques for specific equipment
Maintainability
Maintainability refers to the design of product, machines and processes with an objective of reducing maintenance downtime, resources, specialist tools and skills required to maintain reliability. Design techniques may include modular design for ease of replacement, provision of bypass opportunities to isolate the failure for repair while processes continue or provision of substitute equipment
Monitoring and testing
Monitoring and testing may be undertaken for both corrective and proactive and predictive maintenance. Tests may include:
manual inspections
instrumented monitoring
lubricant testing (tribology)
lidar (light for atmospheric particle detection)
gas chromatography
mandatory inspections
performance and condition monitoring
radiographic examination for material imperfections
microwave for non-metallic solid or liquid test
camera and scope techniques
Maintenance system data
Maintenance system data may include:
asset ID and plant warranties
procedural documents:
monitoring and preventative maintenance schedules
SWMS
MSDS
work permits
monitoring reports and system measurements
maintenance actions and costs
spares inventory control

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 evaluate maintenance systems and processes for safe, cost-effective and sustainable operation.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
investigate sustainability implications of maintenance processes
identify and review features and functions of maintenance and information systems, trends and implementation strategies and software
evaluate safety and risk management, sustainability, asset reliability and maintainability, lean indices, system design parameters, data generation, collection, reporting, storage and analysis, condition monitoring, facilities and services maintenance response systems, asset categorisation, maintenance scheduling and prioritising, and continuous improvement, implemention
audit plant, facilities and services, provision of parts and consumables provision, labour, skills and technical support
report and document results.
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, then a simulated working environment 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.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
