Why do some companies succeed in managing object-oriented projects and others fail? I have reviewed numerous failed object technology projects, and it is clear to me that the single largest failure is technology management, not the technology itself. When they move to object technology, most companies prepare their technical staff by sending them to language and object-oriented analysis and design classes. Unfortunately, these same companies often ignore the training needs of the managers who will be directing the technical staff. Managers are left to fend for themselves, armed with yesterday's tools and with little insight into the potential of today's technology. I describe several project management issues facing companies switching to object technology and offer ways for managers to cope.
