"Parkinson's Law" Mental Model
"Work expands to fill the time available for its completion."

\\\\ A Thread by @Wise_Chimp //

If something must be done in a year, it’ll be done in a year.
If it must be done in six months, then it will.

Parkinson’s Law is named after C. Northcote Parkinson.
During his time with the British Civil Service, he noted that as bureaucracies expanded, became more inefficient.

We plan based on how much time we have, and when the deadline approaches, we start to make Choices and Tradeoffs to do what must be done to complete the task by the deadline.

Ingvar Kamprad, the founder of IKEA, once said, “If you split your day into ten-minute increments, and you try to waste as few of those ten minute increments as possible, you’ll be amazed at what you can get done.”

The law can be generalized further as:
The demand upon a resource tends to expand to match the supply of the resource (If the price is zero).

Parkinson’s Law is best used as a Thought Experiment question:
"What would it look like to finish a project in a very short period of time?"

Also, consider that Parkinson’s Law should not be considered carte blanche to set unreasonable deadlines.

All projects take time.
you certainly can’t build a skyscraper in a day, or a factory in a week.

I hope this mental model has been useful for you.
If it was so, consider RTing the first tweet of this thread.

Also, take a look at my MEGA-THREAD on mental models.
Each day I add new thinking tools to it:
