““If (as is generally accepted) over 75% of a typical software project’s life-cycle costs will be in maintenance and debugging and extensions, then the common price policy of charging a high fixed purchase price and relatively low or zero support fees is bound to lead to results that serve all parties poorly. Consumers lose because, even though software is a service industry, the incentives in the factory model all work against a vendor’s offering competent service. If the vendor’s money comes from selling bits, most effort will go into making bits and shoving them out the door; the help desk, not a profit center, will become a dumping ground for the least effective employees and get only enough resources to avoid actively alienating a critical number of customers.””
