A-Level Business Studies revision: Operations Management. Learning objectives, key points, worked examples and practice questions across AQA, Edexcel, OCR, WJEC and CCEA.
📌 Key Points
Key Fact: Job: one-off, high skill, high cost; Batch: groups, flexible; Flow: continuous, high volume, low variety; Cell: U-shape, multi-skilled; Mass custom: flow + flexibility
Key Fact: QC (inspection) vs QA (prevention); TQM: culture, continuous improvement; Kaizen: small incremental; Six Sigma: DMAIC, 3.4 defects/million; Benchmarking: best practice
Key Fact: Capacity utilisation = actual/max x100%; Efficiency = standard hours/actual hours; Productivity = output/input
Key Fact: Lean: eliminate Muda (overproduction, waiting, transport, over-processing, inventory, motion, defects); JIT: pull system; Kanban: visual signal; 5S: Sort, Set, Shine, Standardise, Sustain
Key Fact: Supply chain: procurement (supplier selection), logistics (transport, warehousing), outsourcing (core vs non-core), supplier development
Key Fact: Industry 4.0: cyber-physical systems, IoT, big data, AI, additive manufacturing, digital twins
🎯 Learning Objectives
- Compare production methods: job, batch, flow, cell, mass customisation
- Evaluate quality management: QC vs QA, TQM, Kaizen, Six Sigma, benchmarking
- Analyse capacity utilisation, efficiency, productivity
- Understand lean production: JIT, Kanban, waste reduction (Muda), 5S
- Analyse supply chain: procurement, logistics, outsourcing, supplier relationships
- Evaluate technology impact: automation, AI, IoT, Industry 4.0
💡 Worked Example
Exam-Style Question
Question: A furniture maker switches from batch to flow production. Analyse implications for cost, quality, flexibility
Model Answer:
Cost: lower unit cost (economies of scale, less setup), but high capital investment. Quality: more consistent (standardised), but defects affect large volumes. Flexibility: reduced (dedicated line), harder to customise. Workforce: deskilling, potential redundancy. Inventory: lower WIP with JIT
