Where should you store information?

A framework based on half-life of knowledge

What is half-life of knowledge?

In nuclear physics, the half-life of a radioactive substance refers to the amount of time taken for it to reduce (decay) to half. Similarly, half-life of knowledge, information or facts refers to the amount of time needed for half of the knowledge to become irrelevant or outdated.

For example: A company's press release or an investor update will typically have a half-life of a couple of weeks. On the other hand, your company's wiki or your SOPs will have a half-life of ~0.5-1 years.

What is this framework?

The half-life of knowledge talks about the time till a particular bit of information would be useful. It naturally follows that different types of information having widely varied lifespans should also have their respective channels.

This framework aims to give you an initial direction as to where a particular piece of information that has been generated is best stored.

Q1. What type of information do you have?

Q2. How long do you want this information to be used?
