Operations management (A Level)

9.1 Location and scale

Location decisions

The location of production or offices depends on cost and market.

Quantitative methods compare costs and revenue at each location; qualitative factors include quality of life and reputation. Offshoring moves production abroad for lower cost; reshoring brings it back, sometimes for quality, speed and control.

Relocation (moving operations to another place) happens when costs rise, the business grows or the market shifts. It brings disruption, redundancy and moving costs, but may cut costs or reach new markets. Globalisation widens the choice: firms can locate abroad to use cheaper labour, new markets, trade agreements and supply networks, and better transport and communications make this easier. This leads to offshoring, but risks include exchange-rate changes, political instability, supply-chain disruption and bad publicity over working conditions.

Scale of operation and economies of scale

Scale is the size of the business's operations. Economies of scale (see Chapter 1) lower unit cost as output rises (purchasing, technical, financial, managerial, marketing). Diseconomies raise it at very large size. External economies arise from the location or industry cluster.

Capacity and the scale decision: expansion needs finance and demand; downsizing (rationalisation) cuts excess capacity at the cost of jobs.

Local, national and international location, and scale

Local location decisions weigh site cost, labour and customers nearby; national decisions compare regions (wages, grants, transport); international decisions add exchange rates, tariffs, culture, language and political risk. Factors affecting scale include the size of the market, finance, technology, owners' objectives and the type of product. Examples: internal economies: bulk purchasing and larger machines; external economies: a skilled labour pool or supporting suppliers nearby; internal diseconomies: poor communication and slow decisions; external diseconomies: congestion or higher local wages in a crowded area. These link to unit cost: economies lower average cost as output rises, diseconomies raise it.

9.2 Quality management

Quality means being fit for purpose and meeting customer expectations. Poor quality causes returns, repair costs, lost customers and reputation damage; good quality allows higher prices and loyalty.

TQM features: quality circles, zero defects, empowerment, supplier quality, right first time. Kaizen is continuous small improvements.

Benchmarking compares performance with the best rivals to find gaps. Quality standards (ISO) give recognition.

Costs: training, inspection, equipment; benefits: fewer defects, less waste, higher sales. A balanced approach is needed, since perfect quality is costly.

9.3 Operations strategy

Operations strategy is the long-term plan for how operations support corporate objectives: cost leadership, quality, speed, flexibility and innovation.

Lean production and efficiency

Lean production cuts waste and inventory while keeping quality: JIT, kaizen, cell production, quality circles, waste management and simultaneous engineering (design, production and marketing teams work at the same time instead of one after another, so a new product reaches the market faster with fewer changes). Cell production splits work into small self-contained teams responsible for a whole part of the process. Limits: lean needs reliable suppliers, committed staff and stable demand, and disruption can stop output. It reduces costs and speeds response but needs reliable suppliers and skilled, flexible staff.

IT and AI in operations

IT and AI are changing operations: automated production and robotics, sensors and the Internet of Things that monitor machines, AI for forecasting demand, scheduling and quality inspection, digital twins and 3D printing. They raise productivity and accuracy and cut waste and downtime, but cost a great deal to install, need new skills, depend on reliable data and security, and can cause job losses.

Flexibility and process innovation

A business needs flexibility in volume (able to change output), delivery time and specification (customised products). Process innovation means changing current processes or adopting new ways of producing goods or delivering services (for example automation or a new layout) to cut cost, speed up output or raise quality. It needs investment and training and carries risk, but can give a competitive edge.

Enterprise resource planning (ERP)

ERP is a software system that links all of a business's data and processes (sales, purchasing, inventory, production, finance, HR) in one shared database. Main features: an integrated database, real-time information, common processes across departments and reporting tools. It improves efficiency by: inventory control (accurate stock levels and automatic re-ordering), costing and pricing (up-to-date costs), capacity utilisation (matching production to orders), responses to change (quick re-planning), workforce flexibility (scheduling) and management information (reports and dashboards). Costs and risks: expensive to buy and install, disruption and training, and a failure can stop the whole business.

Technology and automation

Automation, robotics, computer-aided design and manufacture (CAD/CAM), AI and data analytics raise productivity and quality, reduce error and labour costs, and allow mass customisation. Issues: high investment, job losses, training, system failure and cyber risk.

Supply chain management

The supply chain is the network from raw material to customer. Effective management secures reliable and ethical suppliers, controls cost and lead time and manages risk. Risks: single-source dependence, supplier failure, disruption (events, transport) and ethical failures (child labour). Firms may build long-term relationships, dual-source, or hold buffer stock.

Critical path analysis (CPA)

CPA plans projects by showing activities, their order and duration. A network diagram has nodes with earliest start time (EST) and latest finish time (LFT).

A dummy activity (a dotted arrow with zero duration) shows that one activity depends on another without using any time or resources.

The critical path is the longest path and sets the minimum project time. Delays on it delay the project; non-critical activities have float and can be delayed. Benefits: shows resource needs, identifies priorities, helps time and cost control. Limits: estimates may be wrong, and complex projects need software.

Overall evaluation

A good operations strategy balances cost, quality, speed and flexibility against the business's position. A low-cost producer may sacrifice flexibility; a luxury brand puts quality first.

Operations decisions and lean production

Operations decisions are influenced by human resources (skills and availability of staff), marketing (the demand and quality customers expect) and finance (the funds available to invest in equipment and technology). Lean production aims to cut waste, reduce cost and keep or raise quality; it links to inventory control (JIT), quality (right first time), employees' roles (multi-skilled and empowered), capacity management (flexible) and overall efficiency.
