Principles that Rule

Ever so often we come across a rule or a principle that summarizes a wealth of insight in a line or two. More often than not, we find ourselves nodding our head vigorously in agreement.
This blog is an attempt to compile together such principles and rules, with links pointing to the more useful resources. To start with, here are a few rules that I can think of right now...


Pareto principle:
The Pareto principle, also known as the 80-20 Rule, says that 20% of your work will take 80 % of your time, and vice versa.

Guy Kawasaki’s 10/20/30 rule of PowerPoint:
Guy Kawasaki suggests that a PowerPoint presentation should have no more than 10 slides, shouldn’t last longer than 20 minutes, and shouldn’t have any font smaller than size 30.

20-70-10 Rule:
This rule, which became more famous (or infamous) as Jack Welch’s Differentation method, states that all the workforce in an organization can be divided into three categories: The top 20% (star performers, who must be awarded), the middle 70% (the core of company, who must be nurtured and monitored) and the bottom 10% (the non-performers, who must be moved out).
The Welch Way


2 Minute Rule:
This rule comes from David Allen’s Getting Things Done (popularly known as GTD). It says, a task that can be completed in 2 minutes should be done immediately.


Six degrees of separation:
Six degrees of separation is a wonderful idea which postulates that if you are one step away from each person you know, and two step away from each they know, then you are at most just six steps away from any other person in the world.... yes including the US President!

Rule of 72:
The rule of 72 is a quick (though approximate) method to determine how long an investment will take to double, given a fixed annual rate of interest. To find the time period, just divide 72 with the annual rate of return.
