PMI-SP Exam - Topic 8 Question 22 Discussion

The law of diminishing returns state that the user cannot exponentially add labor to a

project to reduce the amount of time required to complete the project work. In other words, Harry

cannot keep doubling the workforce on this project to reduce the project duration down to

just a few minutes.

The law of diminishing returns state that 'the user will get less and less output when he add

additional doses of an input while holding other

inputs fixed. In other words, the marginal product of each unit of input will decline as the amount of

that input increases holding all other

inputs constant.' Diminishing returns mean that the extra labor causes output to fall, which means

that the MPL is negative. In other words,

the change in output per unit increase in labor is negative and total output is falling.
