The allocation of resources within an R&D organization does not often expli
citly consider the allocation among basic research, applied research, and d
evelopment. However, a misallocation among these phases of research can hav
e adverse consequences, sometimes unexpected, over time. A method of modeli
ng a firm's R&D operation has been developed that uses system dynamics meth
odology and data from the firm's own experience. The model can give insight
into the effects of changing allocations To phases, whether those changes
are internally or externally driven. For example, increasing the share of R
&D resources going to the final phase in order to accelerate the production
of new commercial technologies may succeed in the short run but will event
ually decrease that production in the long run.
