The global market for warehouse management systems grew by 8 percent in 2012. Growth was broad-based, occurring in both well-established and emerging market segments. The WMS replacement cycle is responsible for much of the recent growth in the mature segments. As this dynamic diminishes, more enduring factors will propel future market growth. These factors include expanded adoption of WMS add-on modules, additional upgrades due to the benefits delivered by supply chain execution platforms, and increased demand driven by the omni-channel retail paradigm.
