necessary condition

a condition that is indispensable for the achievement of an objective. A necessary condition is usually contrasted with sufficient condition, which is viewed as the adequacy of a condition to achieve an objective.

For example, an increase in INVESTMENT is a necessary condition in the achievement of higher rates of ECONOMIC GROWTH, but it is not a sufficient condition to generate growth insofar as other factors, such as an increase in the LABOUR FORCE, also contribute to raising growth rates.
