Operations and Production Management

Operations and production management

This domain examines how inputs are transformed into outputs efficiently, reliably and to the required quality. Questions test production methods, capacity, productivity, break-even, inventory and quality systems.

Core rules and concepts

  • Job production makes one bespoke item at a time; batch production makes groups of identical items; flow production uses continuous, highly standardised lines. Mass customisation combines flexibility with scale.
  • Productivity = output ÷ input (often output per worker or per hour). Production is total output; productivity measures efficiency. Capacity utilisation = actual output ÷ maximum possible output × 100%.
  • Break-even output = fixed costs ÷ contribution per unit, where contribution = selling price − variable cost per unit. Margin of safety = current output − break-even output.
  • Lean production reduces waste; just-in-time (JIT) orders stock to arrive as needed, cutting holding costs but raising supply-risk exposure. Kaizen is continuous improvement.
  • Quality control inspects output at the end; quality assurance builds quality into the process; total quality management (TQM) involves everyone and focuses on customer requirements.

Worked example

A workshop has fixed costs of $60,000, variable cost of $40 per unit and a selling price of $100. Contribution is $60. Break-even = 60,000 ÷ 60 = 1,000 units. At 1,400 units, margin of safety is 400 units. If a JIT system cuts fixed storage costs by $6,000 but a supplier failure stops production for a week, the saving may be outweighed by lost contribution. The reasoning: break-even is a planning tool, not a guarantee; JIT trades inventory cost for supply-chain risk.

Traps that cost marks

Do not confuse break-even with the profit-maximising output. Do not treat productivity as total output. Do not say JIT means no stock at all. Do not assume flow production is always cheaper; it requires high volume and stable demand. In calculations, keep fixed costs out of contribution.
