who came up with the idea of smart goals
SMART criteria The November 1981 issue of Management Review contained a paper by George T. Doran called There's a S.M.A.R.T. way to write management's goals and objectives.[1][3] It discussed the importance of objectives and the difficulty of setting them.
Expectancy theory Victor H. Vroom (1964) defines motivation as a process governing choices among alternative forms of voluntary activities, a process controlled by the individual. The individual makes choices based on estimates of how well the expected results of a given behavior are going to match up with or eventually lead to the desired results. Motivation is a product of the individual's expectancy that a certain effort will lead to the intended performance, the instrumentality of this performance to achieving a certain result, and the desirability of this result for the individual, known as valence.[3]
