Workplace Communication and Documentation
Why documentation is examined
Manufacturing depends on records that let work be repeated, audited, and defended. You must know the purpose and typical content of: design drawings and specifications, job cards or work orders, cutting lists, bills of materials, purchase orders, delivery dockets, inspection and test records, maintenance logs, safety data sheets, and incident reports. For each, know who reads it and why.
Drawing conventions
Know orthographic projection (first-angle and third-angle), scale, dimensioning, line types (visible, hidden, centre, dimension), and title blocks. Understand that a drawing is a contractual document: dimensions override scaled measurement. Know what a bill of materials does (quantities and specifications for purchasing) and how it differs from a cutting list (sizes for production).
Workplace communication
Revise toolbox talks, shift handovers, noticeboards, emails, and meetings, and the difference between formal and informal communication. Understand barriers to communication (jargon, noise, language, ambiguity) and how to overcome them (plain language, feedback, standard templates).
Traps
Students confuse a bill of materials with a cutting list. Students describe a document without saying who uses it. Students forget that safety data sheets are a legal requirement for hazardous substances, not optional information.
Rule of thumb
For any document, answer: Who writes it? Who reads it? What decision does it support? If you cannot name the reader, you do not yet understand the document.
Worked example
A work order authorises production of 20 frames; the bill of materials lists 20 lengths of tube and 80 fasteners for purchasing; the cutting list gives exact lengths for the saw operator; the inspection record confirms dimensions were checked against tolerance.
