Methods of production, the meaning and measurement of productivity, stock control including just-in-time, and approaches to quality including quality control, quality assurance and total quality management.

What this dot point is asking

CCEA wants you to describe the main methods of production, explain and measure productivity, describe stock control including just-in-time, and compare approaches to managing quality.

Methods of production

A business chooses how to organise production according to the product and the volume required.

• Job production - making a single, often customised, item at a time, such as a tailored suit or a bespoke building. It allows high quality and flexibility but is labour-intensive and costly per unit.
• Batch production - making a group of identical items together before switching to another batch, such as loaves of bread or a run of clothing in one size. It balances flexibility and efficiency but involves downtime between batches.
• Flow (mass) production - continuous production of large quantities of a standardised product, such as cars or bottled drinks. It achieves low unit costs and high output but is inflexible and needs heavy capital investment.

Productivity and efficiency

Productivity can be raised by training, investing in better technology and machinery, improving motivation, and streamlining processes. Higher efficiency reduces unit costs and helps a business compete on price or earn higher margins.

Stock control

Stock (inventory) includes raw materials, work in progress and finished goods. A business must balance the cost of holding stock against the risk of running out.

• Buffer stock - a minimum level of stock held as a safety margin against delays or demand spikes, providing security but tying up cash.
• Just-in-time (JIT) - stock arrives only as it is needed for production, minimising stock held. JIT cuts storage costs and waste and frees cash, but leaves no safety margin, so it depends on reliable suppliers and accurate forecasting.

Managing quality

Quality means meeting or exceeding customer expectations consistently. CCEA distinguishes three approaches:

• Quality control - inspecting products during or at the end of production to detect and remove faults before they reach the customer. It catches defects but only after they occur, and relies on a separate inspection function.
• Quality assurance - building quality into every stage so faults are prevented, with each worker responsible for their own output against agreed standards.
• Total quality management (TQM) - a whole-organisation culture in which every employee, in every department, is committed to continuous improvement and getting it right first time.

Good quality reduces waste and returns, protects reputation, builds customer loyalty and can justify a higher price; poor quality raises costs and damages the brand.

Why operations matter

Operations decisions determine cost, quality, flexibility and reliability, all of which feed back into the marketing mix and the firm's competitiveness. Efficient, high-quality production lets a business add more value, charge a sustainable price and satisfy customers, linking operations directly to the firm's objectives.

Try this

Q1. State two methods of production. [2 marks]

• Cue. Job, batch and flow (mass) production (any two).

Q2. Explain one benefit to a business of improving its productivity. [3 marks]

• Cue. Higher output per worker lowers the unit cost, improving competitiveness and margins.

Q3. Analyse the benefits to a manufacturer of adopting total quality management. [6 marks]

• Cue. A whole-organisation culture of getting it right first time reduces waste and returns, protects reputation and builds loyalty, though it requires training and commitment from all staff.
