The operations function
Operations is the business function that creates the goods or services a business sells. It is the core value-adding activity, turning resources into outputs that customers will pay more for than the cost of the inputs.
Operations can produce goods (tangible, storable) or services (intangible, often produced and consumed at the same time). Services are usually more customised and rely heavily on staff interaction, while goods production can be more standardised and automated.
Key operations objectives
Operations managers balance several goals: productivity (output per unit of input), quality (fitness for purpose), cost control, flexibility, speed and dependability. Improving one can affect another, so trade-offs are common - for example, very high customisation can reduce productivity.
Strategies to improve operations
Quality management covers three levels. Quality control inspects finished products to detect defects. Quality assurance builds in agreed standards and processes (often certified, such as ISO standards) to prevent defects. Total Quality Management (TQM) is an organisation-wide culture of continuous improvement where every employee is responsible for quality.
Inventory management aims to hold enough stock to meet demand without tying up too much cash or risking spoilage. Just-in-time (JIT) ordering delivers materials only as needed, reducing holding costs but relying on dependable suppliers. The trade-off is greater vulnerability to supply disruptions.
Lean production seeks to eliminate waste in all forms - excess inventory, waiting time, defects, unnecessary movement and over-production - so that resources flow to activities the customer values.
Technology improves operations through automation, robotics, computer-aided design and manufacturing (CAD/CAM), and management information systems. Technology can lift speed, consistency and productivity, but requires capital investment and staff training.
Supply chain management coordinates the flow of materials, information and finance from suppliers through to the customer, often using outsourcing and global sourcing to reduce costs or access expertise.
Sustainability in operations
Modern operations also consider environmental sustainability: reducing energy and water use, minimising waste, and sourcing responsibly. This can lower costs, meet legal and community expectations, and strengthen brand reputation.
In an exam, link each operations strategy to a clear benefit (lower cost, higher quality, faster delivery) and acknowledge the trade-off it brings.
