Marrese was head of marketing for the iSeries for 20 months and, like her predecessors, received some of the most intense criticism and the most free advice among IBM’s many lines of business.

She takes on her new job on November 1, and it will involve all IBM products that are pushed through the channel in the US, Canada, Latin America, Central America, Mexico, and the Caribbean.

Marrese has been replaced by Peter Bingaman, a marketing executive from IBM’s Software Group, who has been spearheading the company’s efforts to create the Express line of relatively low-cost software products for the small and midsized business market.

Bingaman’s title at Software Group was vice president of SMB marketing. Before that, he was director of global marketing for IBM’s data management software. He joined IBM in 1996 from advertising powerhouse Satchi & Satchi, where he was vice president of account services and, among other things, handled the Hewlett-Packard account. Bingaman has a bachelor’s degree in psychology from Bucknell University and an MBA from Duke University.
