Strategies for deveIopment projects: an empirical study*

This paper summarizes results from a study of strategy choices and outcomes in one government laboratory over a fifteen-year time period. Several considerations associated with the effectiveness of a parallel strategy are presented and discussed. These include different types of uncertainty encountered in a given problem and their effect on the rate of learning. Contrary to observations in other studies, the present results suggest that the rate of learning is often slow and may not be facilitated by the use of many parallel approaches in only early project stages. In many instances major uncertainties are not reduced until the product is evaluated in the operational environment.
