Elements and Performance Criteria

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.
Parameters of the brief or contract
The design brief may include the design of new equipment or fault analysis, rectification or modification to an existing design. Parameters to the design brief may include:
design cost and system capital cost
maintainability and product life cycle cost
durability, function, performance and aesthetics
energy and environmental sustainability and social issues
equipment availability and worksite restrictions
other special features and limits in the design brief
CIM
CIM is a method of manufacturing in which the production process is controlled by computer. It may include:
computer-aided design/computer-aided manufacturing (CAD/CAM)
computer-aided process planning (CAPP)
computer numerical control (CNC) machine tools
direct numerical control (DNC) machine tools
flexible machining systems (FMS)
automated storage and retrieval systems (ASRS)
automated guided vehicles (AGV)
use of robotics and automated conveyance
computerised scheduling
production and inventory control
a business system integrated by a common database
Range of solutions
Range of solutions for CIM systems may include:
hardware options, such as:
processing machinery
transfer devices, robots, conveyors, and other automated pick and place devices
materials handling equipment
AGVs
programmable logic controllers (PLCs)
remote terminal units (RTUs)
human, machine interfaces (HMIs), e.g. touch screens
wired and wireless networking systems
software options and systems, such as:
CAD/CAM
CAPP
system control and data acquisition (SCADA)
distributed control systems (DCS)
ASRS
enterprise resource planning (ERP)
quality assurance (QA) and quality control (QC) systems
local area network (LAN) and wide area network (WAN) network communications
OHS, regulatory, sustainability and environmental issues
OHS, regulatory, sustainability and environmental issues may include:
OHS Acts and regulations
relevant standards
industry codes of practice
risk assessments
registration requirements
safe work practices
minimising ecological and environmental footprint of process, plant and product
maximising economic benefit of process plant and product to the organisation and the community
minimising the negative OHS impact on employees, community and customer
state and territory regulatory requirements
Standards and codes
Standards and codes refer to all relevant Australian and international standards and codes applicable to a particular design task
Appropriate software and validation techniques
Software may be employed for:
performance analysis/modelling. Underpinning program techniques and algorithms should be understood, such as the use of FEA and numerical methods within object oriented modelling techniques
Validation techniques include:
comparison of traditional solutions for simple design problems with software solutions to the same design problems
review of previously implemented design challenges which were completed using the software
Network topology
Network topology refers to the arrangement of connected hardware. These include:
bus, ring, star, tree, mesh and in-line (2 way comms.) arrangements
wired and wireless options
Communications protocols
Communications protocols refer to the set of standardised rules for data and signal syntax, checking and error detection. Hardware and software generate data in accordance with a protocol that allows generators and receivers to understand or translate the data as information, control signals integrity and error checks. These include:
layered communications and networking protocols
OSI Model - Open Systems Interconnection Model - 7 layers
TCP/IP Internet Protocol Suite {Transmission Control Protocol (TCP) and the Internet Protocol (IP)} - 4 or 5 layers
IEEE 802 LAN/MAN group of standards, including IEEE 802.3 Ethernet standard, IEEE 802.11 Wireless Networking standard
interface standards, such as RS232 and RS485, Fieldbus, Modbus and DNP3.0
Automation safety
Automation safety refers to the reliance on emergency stop, failsafe design, redundancy, interlocks and data integrity. Standards apply to general plant design and use as well as the functional safety of safety-related electrical, electronic and programmable electronic control systems.

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.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
interpret features of plant and equipment and parameters to the brief or contract
advise client based on discipline knowledge and OHS and regulatory standards
research sustainability implications and current industrial design techniques
determine OHS, regulatory and risk management requirements
investigate and measure
model and calculate using appropriate software and validation techniques
generate and evaluate a range of solutions for feasibility against design criteria
design CIM system solution
communicate, negotiate and review with stakeholders and client throughout process to obtain agreement on proposal and sign-off on design
document design with drawings, specifications and instructions.
Context of and specific resources for assessment
This unit may be assessed on the job, a combination of both on and off the job, or off the job if suitable design and simulation facilities to test the design are available. Where assessment occurs off the job, that is, the candidate is not in productive work, 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 its 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 able not only 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.
