ECS can be explained in terms of “The prospects Theory” as presented by Kahneman and Tversky (1979), because humans are loss aversive by design so they require compensations for maximizing the prospects. “Cognitive Evolution Theory” as explained by Weiner (1972) is also an account of compensation emerging from motivation and reward. Since the motivation and reward are directly linked with the success of an organization so evidently ECS is linked with project success in a project-based organization.
