Test Smarter with the 80:20 Rule

In 1963, IBM found about 80 percent of a computer's time was spent executing only computer's 20 percent of the instructions, which was a counter-intuitive breakthrough at the time. IBM rewrote the operating system to make the 20 percent faster and easier to use, improving computer performance. RISC computing is based on this principle as well. Web traffic also follows the Pareto Principle, with 10 percent of web sites having 90 percent of traffic. This article discusses how to improve your testing skills by using the 80:20 rule, (a.k.a. The Pareto Principle).
