Two business writers and consultants chronicle IBMs rise to computer industry dominance in the 1970s through its decline in the early 1990s when this book was first published. Examining implications at the time for computer companies entering a period of vast opportunity and international competition, the chapters include the rise of the clones, competing in radically decentralized systems, and toward an American technology policy.
