Management and Planning: Projects, Safety and Documentation
Plan the work, then work the plan
A strong answer uses a recognised planning structure: goal setting, task breakdown (work breakdown structure), sequencing and dependencies, resource allocation, time scheduling (Gantt chart or critical path), and monitoring with contingency. Know that the critical path is the longest dependent sequence and therefore sets the minimum project duration; delay on it delays the whole project.
Documentation and control
Be able to describe a production plan (operations, sequence, time, personnel, equipment), a cutting list or bill of materials, a process sheet, and a quality plan. Know quality control (inspection of output) versus quality assurance (systems designed to prevent defects). Include risk assessment with the hierarchy of control: eliminate, substitute, engineer, administrate, then PPE as last resort.
Traps that appear in questions
- Confusing a Gantt chart with a critical path. The chart displays tasks over time; the critical path identifies which delays matter.
- Listing risks without controls, or jumping straight to PPE.
- Ignoring dependencies and scheduling two tasks that need the same machine.
- Treating cost and time as independent when a crash programme trades money for duration.
- Vague monitoring. Say what you would check, when, and what you would do if it slipped.
Worked example
A bench project has four tasks: mark out (2 h), cut (3 h, after marking), assemble (4 h, after cutting), finish (5 h, after assembly). The dependent chain totals 14 h, so that is the critical path and the earliest completion time; adding a second worker to finishing does not shorten it because finishing cannot start earlier. Rule of thumb: find the longest dependent chain first, then decide where extra resources actually help.
