Corporate investments in new product development (NPD) initiatives are strategically effective activities that are instrumental in contributing to new product performance. Given that a fundamental nature of product development is the ability to exploit new product opportunities, the authors investigate the firm-level impact that corporate investments in knowledge workers and financial NPD resources have on new product performance. They track the resource dedication and new product financial performance of 41 firms over a seven-year period. Our results provide evidence that financial investments have a contemporaneous return on investment while knowledge worker investments provide companies with both contemporaneous and carryover returns. When formulating strategy and making NPD resource allocation decisions, managers must remain cognizant of the time-dependent nature of resource investments, the need for persistent investment, and the resulting performance impact.
