In most cases these companies chose or were forced to engage in a technology partnership in order to develop and survive. As one would expect, some of these partnerships succeeded whilst others failed. With hindsight it occurred to the author that success or failure was not necessarily a random event, or idiosyncratic to one particular company, but that there seemed to be a pattern. Some partnerships failed because they were a strategic misfit, others probably because they were badly implemented. Based on these clinical case studies, The author addresses these questions: when and under what conditions a partnership is needed; what form should it take; and what observations can be made about the successful management of these partnerships?
