Efficiency in production refers to the idea of producing a given output with the lowest cost possible, using the optimal combination of factors of production such as labor, capital, and raw materials. It's about making the best use of available resources to produce goods and services. This can be achieved through a variety of means, such as the adoption of capital-intensive technology, improving the process and production techniques, or by finding ways to reduce waste and inefficiencies in the production process. The goal is to produce the desired output with the least amount of waste and at the lowest possible cost. Reducing the size of the workforce may be one way to achieve efficiency, but it is not the only way, and it may not always result in the best outcome.
