Efficiency

Efficiency refers to the ability to achieve a desired result with the least amount of wasted time, effort, or resources. It is a measure of how well a system, process, or individual performs in accomplishing a task relative to the inputs used. In broader contexts, efficiency can involve optimizing performance, minimizing costs, and maximizing output or productivity.

In various fields, such as engineering, economics, and business, efficiency can be quantified and assessed through different metrics. For example, in manufacturing, it may relate to the rate of production versus the amount of raw materials consumed. In energy, efficiency might refer to the ratio of useful energy output to total energy input.

Overall, the concept of efficiency emphasizes the importance of making the best use of available resources to minimize waste and enhance performance.
