Final answer:
Work simplification can increase operating efficiency in a stable environment and is thus considered true. It streamlines processes, and along with economies of scale, can significantly improve productivity.
Step-by-step explanation:
Work simplification refers to the process of improving efficiency by breaking down jobs into simpler component parts, optimizing each part, and removing unnecessary steps. The idea is that a streamlined process will decrease the time taken to complete a task, thereby increasing operating efficiency. This approach can be particularly effective in a stable environment where processes and outputs are predictable and consistent, allowing for the refinement of tasks without having to adapt to frequent changes.
Answering the question, work simplification can increase operating efficiency in a stable environment, the statement is True. As for the efficiency of simple machines, it is indeed True that the efficiency is always less than 100 percent due to friction causing some of the input work to be converted to heat energy.
In relation to economies of scale, they are cost advantages that industries obtain due to size, such as having access to more efficient equipment. This can allow for higher productivity, as in the example of a worker producing more loaves of bread thanks to a larger industrial-size oven compared to a residential size oven.
