| − | Parkinson describes how work is elastic in its demands on time. Work becomes more complex as to fill the time before completion. He uses the example of how the bureaucracy of the British Civil Service grew unrelated to the amount of work. The growth depended on two factors: (1) The Law of Multiplication of Subordinates and (2) The Law of Multiplication of Work. He formulated a mathematical formula to determine the increase in staff in any public administrative department.<ref name="Essay" />

| − | Parkinson's Law explains the behavioural aspect of scheduling. According to Parkinson's Law, a person will spent all the available time to complete a task regardless of the tasks size. This results in inefficient use of time and effort. Project managers can use this to understand employees motivation for completing tasks. In project schedule management, this is valuable knowledge when estimating activity duration. The project manager should account for this tendency when scheduling to enhance productivity.<ref name="guide"> Project Management Institute, Inc. (September 22, 2017).
