32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Hierarchy of control
- Ranked risk controls from most to least effective: eliminate, substitute, isolate or engineer, administrative controls, then personal protective equipment. PPE is the last defence.
- Risk assessment formula
- Risk equals likelihood multiplied by consequence. Assess each hazard before and after controls to determine residual risk and record it in a risk register.
- Industrial relations
- The system governing relationships between employers, workers and unions, covering awards, enterprise agreements, negotiation, conciliation and arbitration of disputes, and unfair dismissal protections.
- Structural industry issue
- A physical or organisational feature of an enterprise such as site layout, building capacity, services, access and egress, or organisational structure that constrains or enables production.
- Design brief
- A statement defining the problem, intended user, purpose and constraints of a design task. It guides research and is converted into measurable specifications for later evaluation.
- Critical path
- The longest chain of dependent tasks in a project network. It determines the minimum project duration, and any delay on it delays the whole project.
- Gantt chart
- A bar chart showing project tasks against a time scale, indicating start and finish dates, duration, sequence and progress. It supports planning and monitoring.
- Communication model
- Sender encodes a message, transmits it through a channel, receiver decodes it, and feedback confirms understanding. Noise such as physical, semantic or psychological interference distorts it.
- Design specifications
- Measurable, testable requirements derived from the design brief, such as dimensions, tolerances, cost limits, deadlines, safety and sustainability criteria used to evaluate the final product.
- Vernier caliper
- A measuring instrument with a main scale and sliding vernier scale, typically reading to 0.02 millimetres. It measures internal, external and depth dimensions.
- Thermoplastic versus thermoset
- Thermoplastics soften and can be reshaped on reheating; thermosets cure irreversibly and cannot be remelted. The distinction determines whether recycling or reshaping is possible.
- Statistical process control
- A quality technique plotting measured process data on control charts with upper and lower limits, distinguishing normal variation from assignable causes requiring correction.
- Break-even quantity
- Fixed costs divided by the difference between unit price and variable cost per unit. It is the output at which total revenue equals total cost.
- Quality assurance
- The planned system of procedures and checks that builds quality into production processes, in contrast to quality control, which inspects and tests output after production.
- Lean manufacturing
- A production philosophy removing waste while adding value, using value-stream mapping, flow, pull scheduling and continuous improvement. The seven wastes include overproduction, waiting, defects and inventory.
- CNC machining
- Computer numerical control uses coded instructions to control machine tool movements. It delivers repeatable accuracy and complex geometry but requires programming and setup expertise.
- Additive manufacturing
- Building a part layer by layer from a digital model. It enables internal geometry and low-volume customisation but is limited by build size, speed and directional strength.
- Cellular layout
- A group technology layout arranging machines into cells that each produce a family of similar parts, balancing the flexibility of process layout with the efficiency of line layout.
- Third-angle projection
- The Australian standard drawing convention where each view is placed on the side of the object from which it is viewed, giving arrangement of top view above front view.
- Delivery docket
- A document accompanying goods that lists items and quantities supplied, signed on receipt. It evidences delivery and is matched against the purchase order and invoice.
- Meeting minutes
- The formal written record of a meeting stating date, attendees, agenda items, decisions and action items with responsible persons and due dates.
- Version control
- A recordkeeping practice tracking document revisions with identifiers, dates and authors, ensuring the current approved version is used and earlier versions remain retrievable.
- Reasonably practicable
- The WHS test weighing likelihood and severity of harm against what is known, and the availability, suitability and cost of controls. It sets the standard of duty.
- Safety data sheet
- A standardised document for a hazardous chemical listing hazards, safe handling, storage, first aid, spill response and disposal. It must be accessible to workers using the chemical.
- Notifiable incident
- Under harmonised WHS law, a death, serious injury or illness, or dangerous incident that the person conducting the business must report to the regulator immediately.
- Life cycle analysis
- Assessment of a product's environmental impact across all stages: raw material extraction, manufacture, distribution, use, and disposal or recycling.
- Design folio
- A chronological, dated record of the design process containing needs identification, brief, specifications, research, ideas, development, testing, production records and evaluation.
- Measurable specification
- A requirement expressed as a value with units and a test method, such as load capacity in kilograms or maximum cost in dollars, enabling objective evaluation.
- Product evaluation
- A judgement of the finished item against each original specification, using recorded test results and evidence, plus recommendations for improvement.
- Process evaluation
- A review of how the project was managed, covering planning accuracy, time and cost against budget, safety, decisions made and what would be changed next time.
- National Employment Standards
- Eleven minimum employment entitlements in Australian law covering maximum weekly hours, leave types, notice, redundancy pay, and fair work information statements.
- Pareto analysis
- A prioritisation technique showing that roughly 80 percent of problems arise from about 20 percent of causes, directing improvement effort to the few highest-impact causes.
