Wiktionary
n. (context idiomatic English) A condition in which additional inputs into an organization, project or process produce progressively fewer or lower-quality additional outputs, and may, in extreme cases, cause the total quantity or quality of outputs to decrease.

In economics, diminishing returns (also called law of diminishing returns, law of variable proportions, principle of diminishing marginal productivity, or diminishing marginal returns) is the decrease in the marginal (incremental) output of a production process as the amount of a single factor of production is incrementally increased, while the amounts of all other factors of production stay constant.
The law of diminishing returns states that in all productive processes, adding more of one factor of production, while holding all others constant (" ceteris paribus"), will at some point yield lower incremental per-unit returns. The law of diminishing returns does not imply that adding more of a factor will decrease the total production, a condition known as negative returns, though in fact this is common.
A common sort of example is adding more workers to a job, such as assembling a car on a factory floor. At some point, adding more workers causes problems such as workers getting in each other's way or frequently finding themselves waiting for access to a part. In all of these processes, producing one more unit of output per unit of time will eventually cost increasingly more, due to inputs being used less and less effectively.
The law of diminishing returns is a fundamental principle of economics. It plays a central role in production theory.
Usage examples of "diminishing returns".
First, we must study the energy and personnel parameters for critical technologies, balance the input and output against the wastes and other diseconomies, and then pinpoint areas of diminishing returns, where the use of more high technology may not produce commensurate benefits.

But the proper way to project the curve is dotted line number four-for there is no reason, mathematical, scientific, or historical, to expect that curve to flatten out, or to reach a point of diminishing returns, or simply to go on as a tangent.
