Ninety-ninety rule

Index Ninety-ninety rule

In computer programming and software engineering, the ninety-ninety rule is a humorous aphorism that states: This adds up to 180%, in a wry allusion to the notoriety of software development projects significantly over-running their schedules (see software development effort estimation). [1]

Lindy effect

The Lindy effect is a concept that the future life expectancy of some non-perishable things like a technology or an idea is proportional to their current age, so that every additional period of survival implies a longer remaining life expectancy.

Pareto principle

The Pareto principle (also known as the 80/20 rule, the law of the vital few, or the principle of factor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.

Small matter of programming

In software development, small matter of programming (SMOP) or simple matter of programming is a phrase used to ironically indicate that a suggested feature or design change would in fact require a great deal of effort; it often implies that the person proposing the feature underestimates its cost.

Software development effort estimation

Software development effort estimation is the process of predicting the most realistic amount of effort (expressed in terms of person-hours or money) required to develop or maintain software based on incomplete, uncertain and noisy input.
