There is an increasing concern amongst R&D managers and their immediate 'customers' and sponsors within companies to have reliable mechanisms to direct R&D simultaneously toward effective rapid innovation and accumulation of long term technological strength. This is leading R&D managers to seek analytical tools to help them identify technologies which have particular significance for competitive advantage, for multiple SBUs, and for longer term strategic positioning, and to manage them in ways which do not leave them at the mercy of business unit strategies, but situate them closer to the core of corporate strategies. This paper conducts an examination of the parallel literature on the idea of core competencies as a new paradigm in corporate strategy and shows that core competencies can be useful focusing devices for assisting in the creation of this linkage between the technological and non-technological aspects of the corporate strategy agenda. Implications are drawn out for: R&D decisions in the areas of shaping strategic research programmes; funding and organisation regimes for R&D; and measuring the effectiveness of R&D.
