Definition
Efficiency is the degree to which resources are utilised with minimal waste while achieving a defined output. It reflects how economically time, materials, energy, labour and capital are converted into results.
Human Explanation
Efficiency is about using resources wisely. Two processes may produce the same result, but the more efficient one achieves it with less time, effort, energy, material or cost.
Why it Matters
Improving efficiency reduces unnecessary resource consumption, operating costs and waste while maintaining the required output. It helps organisations achieve more with the resources already available.
Conceptual Boundary
Efficiency is not the same as effectiveness or productivity. A process may be highly efficient while producing the wrong outcome, and increasing efficiency does not automatically improve overall system performance.
Practical Perspective
Improving local efficiency should never become the objective by itself. Saving time or resources in one part of a process may create delays, bottlenecks or additional waste elsewhere in the system.
