Efficiency

Efficiency refers to the ability to achieve a desired outcome with the least amount of wasted resources, such as time, energy, or materials. It emphasizes maximizing productivity while minimizing effort and expenditure, often expressed as a ratio of output to input. In various contexts, efficiency can pertain to processes, systems, organizations, or machinery, focusing on how well they convert inputs into outputs. In economic terms, efficiency can also relate to the optimal allocation of resources to achieve the best results.

Efficiency is often quantified and analyzed in fields like engineering, economics, and environmental science, where improving efficiency can lead to cost savings, enhanced performance, and reduced environmental impact. The concept contrasts with effectiveness, which is about achieving goals successfully regardless of the resources spent. Thus, a highly efficient process is one that not only meets objectives but does so in a resource-conserving manner.
