HSC Industrial Technology Practice Questions

A business can define who releases drawings, who schedules work and who has authority to stop a job for unclear information. A controlled hand-off might require the designer to issue a numbered revision and bill of materials through a shared system, followed by a short production review of material, tooling and critical dimensions. Operators record questions and non-conformances against the job rather than relying on memory. This structure shortens clarification time, prevents use of superseded drawings and sends production evidence back to design. Its effectiveness should be judged through wrong-revision incidents, rework and approval lead time, not merely the existence of an organisational chart. A controlled job number should connect the approved brief, drawing revision, bill of materials and work instruction. For example, if a client changes a cabinet width, design records the request and issues the revision; production confirms affected stock and stops the obsolete job; purchasing updates hardware if needed. A short design-production review can resolve questions, while the revision register preserves decisions. Improvement can be checked through fewer clarification stops, wrong-revision parts and rework hours. Marking guidance: For four marks, name the release and stop-work roles, then describe one controlled hand-off in sequence. Credit depends on the mechanism: a numbered revision, acknowledgement and feedback route must lead to fewer clarification stops or wrong-revision parts. A chart with department names alone does not answer how communication improves.
