Parkinson’s law concludes that public administration automatically grows 5.75% year-over-year regardless of circumstances.

Parkinson’s law concludes that public administration automatically grows 5.75% year-over-year regardless of circumstances. He proposes this formula to describe the growth:

100(2k^m + p) / yn

where k is the number of people looking to grow their career through growing their orgs, p meaning the average lifespan of the career to retirement, m is the person-hours spent performing communications review within the department, n is the number of people being overseen, y is the n of the previous year, and x is the number of people required next year. This is all in part observed from the administrative growth seen in the early 20th century British navy, which was undergoing a dramatic reduction in actual activities and assets to oversee in the same period.rP2
