Parkinson's Law

Parkinson's Law is the adage first articulated by Cyril Northcote Parkinson as the first sentence of a humorous essay published in The Economist in 1955:^[1][2]

Work expands so as to fill the time available for its completion.

It was later reprinted together with other essays in the book Parkinson's Law: The Pursuit of Progress (London, John Murray, 1958). He derived the dictum from his extensive experience in the British Civil Service.

The current form of the law is not that which Parkinson refers to by that name in the article. Rather, he assigns to the term a mathematical equation describing the rate at which bureaucracies expand over time. Much of the essay is dedicated to a summary of purportedly scientific observations supporting his law, such as the increase in the number of employees at the Colonial Office while Great Britain's overseas empire declined (indeed, he shows that the Colonial Office had its greatest number of staff at the point when it was folded into the Foreign Office because of a lack of colonies to administer). He explains this growth by two forces: (1) "An official wants to multiply subordinates, not rivals" and (2) "Officials make work for each other." He notes in particular that the total of those employed inside a bureaucracy rose by 5-7% per year "irrespective of any variation in the amount of work (if any) to be done."

In 1986, Alessandro Natta complained about the swelling bureaucracy in Italy. Mikhail Gorbachev responded that "'Parkinson's Law works everywhere."^[3]

[edit] Corollaries

In time, however, the first-referenced meaning of the phrase has dominated, and sprouted several corollaries: for example, the derivative relating to computers:

Data expands to fill the space available for storage.

or

Storage requirements will increase to meet storage capacity.

or

Nature abhors a vacuum.

In terms of computer executable code filling CPU resource (see software bloat), a similar law is Wirth's law.

A second aphorism, attributed to Parkinson and sometimes called "Parkinson's second law", is "expenditures rise to meet income".

A modern version is that no amount of computer automation will reduce the size of a bureaucracy.^[4]

The Stock-Sanford Corollary to Parkinson's Law reads, "If you wait until the last minute, it only takes a minute to do." If a task can expand to fill the time allotted, then conversely, the effort given can be limited by limiting the allotted time, down to a minimum amount of time actually required to complete the task. This phrase is often associated with procrastination.

[edit] Generalization

"Parkinson's Law" could be generalized further still as:

The demand upon a resource tends to expand to match the supply of the resource.

An extension is often added to this, stating that:

The reverse is not true.

This generalization has become very similar to the economic law of demand; that the lower the price of a service or commodity, the greater the quantity demanded.

[edit] Related efficiency

Parkinson also proposed a rule about the efficiency of administrative councils. He defined a coefficient of inefficiency with the number of members as the main determining variable.

Some define Parkinson's Law in regard to time as:

The amount of time in which one has to perform a task is the amount of time it will take to complete said task.
