What do these companies have in common: Amoco (oil), Bethlehem Steel (steel), Compaq (computers), Saab (cars), Lehman Brothers (investments), PanAm (air carrier), F.W. Woolworth (retailer). Polaroid (instant film)? Well they all vanished. Disappeared. You will know many examples yourself. All of these companies were once very big, global operating companies. Some were disrupted like Compaq (the same happened to IBM, but it reinvented itself), others were mismanaged (like Saab and Compaq. Compaq’s CEO Eckard Pfeiffer is on Wall Street’s list of worst CEOs in American history) or failed to respond quickly to available data on customers and markets (like Polaroid).
