Final answer:
A manager might suggest breaking down a decision into multiple sequential decisions to avoid 'escalation of commitment,' by allowing for evaluation at each stage, using a cost/benefit analysis for each small step and relying on a structured decision process over an 'illusion of control'.
Step-by-step explanation:
A manager advocating for breaking down a decision into multiple sequential decisions aims to increase the likelihood of a successful outcome by evaluating the project at each stage. This approach mitigates the risk of 'escalation of commitment,' which is the tendency to continue investing in a project despite evidence of its failing viability. By assessing the project at various points, the manager can make informed decisions about whether to proceed, adjust, or terminate the initiative, thereby avoiding the sunk cost fallacy and impulsive continued investment.
Breaking a decision into smaller steps also relates to the concept of a 'cost/benefit analysis,' where the costs and benefits of each incremental step are weighed against each other. This systematic consideration of the marginal costs and marginal benefits helps in deciding the course of action at every stage of the project.
The structured decision process also includes evaluating each option against set constraints and criteria which facilitates evidence-based decision making over an 'illusion of control,' where one might overestimate their ability to influence outcomes.
