What Is Efficiency?

Efficiency refers to the ability to achieve desired results with limited resources and waste reduction strategies, with an eye toward increasing productivity and eliminating wastage.

Efficiency is often confused with effectiveness; however, they are two different concepts. Effectiveness focuses on quality and impact while efficiency seeks to minimize costs and time usage. Understanding this distinction between them is vitally important.


Efficiency refers to how something operates without wasting materials, time or energy. Although applied to people and things alike, efficiency is most commonly applied to machines, systems, buildings and organizations as a measure of their ability to produce maximum output with minimum input.

Efficiency in business means staff members focusing on meeting goals that support the organization’s growth strategy and increase revenue, and making effective use of cash, human capital, and production equipment resources.

Effectiveness is an intangible quality, while efficiency can be measured using ratios like output to total input. Efficiency measures waste reduction using techniques like data envelopment analysis. Not to be confused with productivity which measures output quantity rather than efficiency which focuses on waste elimination through materials, time or effort waste elimination; companies who improve their efficiency can lower costs while improving competitiveness and remain viable businesses.


Efficiency can be measured as the ratio between useful output and total useful input, and effectiveness, which can be more difficult to evaluate but refers to desired outcomes such as an energy-efficient furnace that uses less fuel and produces fewer emissions than its conventional counterpart.

An efficient employee works at their maximum potential during scheduled shifts without devoting time to unproductive activities, while an efficient retail store carries only enough inventory to satisfy customer demand without overstocking.

An ineffective employee wastes too much time on nonproductive tasks and makes few sales. Judith sold 1,100 valves per week despite Bob being more effective; this could be explained by meetings, commutes and socialization with colleagues reducing inefficiency; however she could improve it by adopting a team calendar which eliminates duplicate data entry and delays caused by switching back and forth between applications.


Economies of scope refers to efficiencies gained through offering an assortment of products. This business strategy can reduce unit costs and make companies more cost-competitive; however, product diversification must be evaluated carefully to avoid unintended negative repercussions; before taking this route a company must also assess supply chain issues, financial implications and the environmental implications before moving ahead with this initiative.

Economy of scope occurs when similar raw materials and production processes are utilized to produce various, yet related goods. For instance, a restaurant serving chicken fingers and French fries may use their existing cold storage and fryers to produce both items at lower costs than two separate establishments would.

Efficiency can be found through business strategies such as flexible manufacturing, product diversification, supply chain alignment and M&A. Offering multiple products can also increase marketing effectiveness by reaching more people with one ad spend. Energy efficiency measures focus on lowering Scope 1 emissions; typically using renewable electricity sources or low carbon electricity and capturing emissions that would otherwise go unchecked.


Though efficiency is the cornerstone of economics, its boundaries must also be considered. A company seeking technical efficiency might aim to get maximum output from minimal inputs – which can result in reduced quality at times as Ranjana Mukherjee noted in World Bank’s “Micro-Economic Indicators” publication from July 2000. Allocative efficiency represents an ideal that’s very difficult to attain in reality due to assumptions made regarding marginal social costs that would need to be made about marginal costs of production and so forth.

Focusing on efficiency alone may also decrease operational flexibility for organizations. Routine processes and limited resources often limit how managers react to changing business conditions or develop market-beating innovations.

Efficiency can be defined as maximizing benefits from available resources. This may involve cutting measurable costs such as labor or materials or marginal ones like energy. Or it might mean prioritizing tasks with higher value and making strategic changes accordingly; for instance, students might improve their academic performance by strategically completing assignments during class time and maintaining consistent study routines.
