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:

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

In Software:

Software Bloat: Data expands to fill the space available for storage.

Example: Too many to list.

In Academics:

Student syndrome refers to the phenomenon that many people will start to fully apply themselves to a task just at the last possible moment before a deadline

Example: Cramming before a midterm.

In Business:

Expenditures rise to meet income and NO amount of computer automation will reduce the size of a bureaucracy.

Example: Australian Tax Office.
