IBM Corp moved swiftly to stem the bleeding at Lotus Development Corp, naming two Lotus insiders to run the subsidiary. Michael Zisman and Jeffrey Papows will form a new office of the president, replacing Jim Manzi. Both are senior vice-presidents in Lotus’s communications business. Zisman was named executive vice-president and chief executive and Papows was named executive vice-president and chief operating officer. They will report to IBM senior vice-president John Thompson. IBM also said that Robert Weiler, senior vice-president of its desktop business group and international sales, has resigned, but a Lotus spokesman said John Landry, chief technology officer, remains with Lotus, although industry sources told Reuters on Friday that Landry is poised to follow Manzi out, possibly within a week. He is currently working on an integrated strategy for the Internet.
