With many of the most important new military systems of the past decade produced by small firms that won competitive government contracts, defense-industry consultant James Hasik argues in "Arms and Innovation" that small firms have a number of advantages relative to their bigger competitors. Such firms are marked by an entrepreneurial spirit and fewer bureaucratic obstacles, and thus can both be more responsive to changes in the environment and more strategic in their planning. This is demonstrated, Hasik shows, by such innovation in military technologies as those that protect troops from roadside bombs in Iraq and the Predator drones that fly over active war zones and that are crucial to the war on terror.For all their advantages, small firms also face significant challenges in access to capital and customers. To overcome such problems, they can form alliances either with each other or with larger companies. Hasik traces the trade-offs of such alliances and provides crucial insight into their promises and pitfalls.This groundbreaking study is a significant contribution to the understanding of both entrepreneurship and alliances, two crucial factors in business generally. It will be of interest to readers in the defense sector as well as the wider business community.
