Increasingly, hardware producers and software developers are falling over each other to be first to market with even newer and even more improved versions. To use IT-intensive products effectively, consumers often must make long-term financial and nonfinancial investments in the product or in the overall system; they expect to be able to use the product for an extended period before having to repeat the investment. The rapid introduction of new and improved versions can make a consumer regret a previous purchase, hesitate over any new purchase, and agonize over similar purchases in the future. It is not in a producer’s long-term interest if consumers balk. The author articulates the underlying reasons for — and the consequences of — adverse consumer reaction to rapid product improvement and offers suggestions for mitigating some of these reactions.
