Modern Day Variations of Parkinson's Law
Parkinson's Law in its original form was postulated in 1955. While it still is very relevant in today's context, it has spawned many off-shoots and variants which best describe certain scenario's in today's world.
One such variant, with respect to data and storage space is as follows:
"Data always expands to fill the space available for storage."
Another variation of this used to refer to software bloat (presence of unnecessary/unwanted features in software). known as Wirth's Law, is described below.
"Software is getting slower more rapidly than hardware is getting faster."
Another law sometimes attributed to Parkinson is the impact on an individual's marginal propensity to save, his rise in spending power, and his chronic inability to save in spite of an increase in income. This is explained in the following summary.
"Expenditures rise in order to meet the increase in income.". This highlights the need for (or) the importance of budgeting.
Thus a broad generalization of Parkinson's Law can be as described below.
"The demand upon a resource tends to increase in order to match the availability/supply of that resource."
