Compaq has lost its fourth top dog in a month, with the departure of its head of services. Compaq senior vice president and general manager of services, John Rando, will resign as soon as a replacement is named, effective from 1 July, said the company. His departure will enable him to pursue personal interests, according to a Reuters report. Rando was brought into the company last June when Compaq swallowed Digital. He joined Digital's services group in 1976 as a software specialist, eventually rising to senior vice president. His sudden resignation from the $6.5 billion computer services unit is the latest in a string of departures. Last month saw the ousting of CEO Eckhard Pfeiffer from the Houston-based computer giant. Pfeiffer left after Compaq warned that first-quarter profits would fall short of Wall Street expectations. Earl Mason, Compaq CFO, and Michael Heil, Compaq sales chief, have both subsequently been given the order of the boot. The announcement was described by industry analyst Carl How at Forrester Research as "part of a changing of the guard at Compaq." "There is a power struggle going on," he told Reuters. ® Click here to email Linda Harrison
