Gary Latham

Gary Latham is an organisational psychologist and Edwin Locke's co-author on goal-setting theory across more than three decades. Their 2002 review in American Psychologist is the standard summary of how specific, difficult goals affect performance.
Who they are
Latham is an organisational psychologist, long associated with the University of Toronto. He and Edwin Locke worked together on goal-setting theory for more than thirty years, producing a 1990 book-length review and the 2002 retrospective in American Psychologist.
Goal-setting theory was tested in workplaces as well as laboratories, and the 2002 review draws on both. It is regarded as one of the better-supported theories in organisational psychology, with conditions attached to its main finding.
Latham is not an author of The 4 Disciplines of Execution. He appears in the Why We Project because the research he and Locke reported overlaps with part of that framework, and the article What are the 4 Disciplines of Execution? cites the 2002 review for that overlap.

Key ideas
The 2002 review summarises a finding with conditions. Specific, difficult goals generally produced higher performance than an instruction to do your best, through four routes: attention, effort, persistence and strategy. See Goal Setting Theory.
The conditions the review states are feedback on progress, commitment to the goal, ability, and task complexity. Goals combined with feedback performed better than goals alone, and the effect was smaller on complex tasks where the difficulty lies in finding a strategy.
The feedback condition links the theory to research on Progress Monitoring. The idea of a specific, demanding target appears in management frameworks such as the Wildly Important Goal discipline in The 4 Disciplines of Execution.
