"The acquisition of WDS brings Manugistics important clients, deep expertise and proven technology to help us maintain our strong momentum in asset-intensive industries such as the aerospace and defense and government sectors. This will also help to drive our Service and Parts Management suite across automotive, aviation, communications, high technology, transportation and other asset-intensive sectors," said Greg Owens, chairman and CEO of Manugistics. "We look forward to applying nearly a half-century of combined Manugistics and WDS experience in supply-demand chain technology to help our clients maximize the profitability of capital assets over the entire lifecycle."
