Parkinson's Law in Project Management
Parkinson's Law states that work expands to fill the time available for its completion.[1] It was formulated by British historian and author Cyril Northcote Parkinson in an essay for The Economist in 1955.[2]
Originally, Parkinson's Law described how a bureaucracy can grow unrelated to its actual workload because people make work for each other by complicating work. The growth of bureaucracy depends on two factors: (1) The Law of Multiplication of Subordinates and (2) The Law of Multiplication of Work. From statistical analyses, he determined the increase in staff per year to be around 5-7% independent of its workload. Based on this, he formulated a mathematical formula to determine the annual increase in staff in any public administrative department.[1]

Theory
In Parkinson’s essay from 1955, the law refers to the relationship between the bureaucracy and its workload. The law describes how people make work for each other by complicating the work. Therefore, a bureaucracy can grow unrelated to its actual workload. The growth depends on two factors: (1) The Law of Multiplication of Subordinates and (2) The Law of Multiplication of Work. The Law of Multiplication of Subordinates states an overworked person, seeking promotion, in an organisation has incentives to multiply subordinates instead of creating rivals by sharing their work. The Law of Multiplication of Work states that people will make work for each other by complicating it so everyone is occupied. This gives the impression that the staff is overworked and missing resources. Therefore, more staff is hired.
Parkinson uses the bureaucracy of the British Civil Service as an example of Parkinson’s Law. He supports his statements with statistical analyses showing that the number of ships and men in the royal navy fell between 1914 and 1928, while the number of employees in administration rose. With these analyses, he determined the rate of staff per year to be around 5-7% independent of the amount of work. He formulated the following mathematical formula to determine the annual increase in staff in any public administrative department.[1]
- k = number of staff with incentives multiply subordinates
- p = the difference between the ages of appointment and retirement
- m = number of hours devoted to answering minutes within the department
- n = number of effective units being administered
- x = number of new staff each year
