Warehouse management systems (WMS) may seem like dinosaurs to us now, but the truth is they are still the work horses of the industry. Despite sometimes being 10 to 15 years old and clunky, organizations are slow to upgrade or abandon their own WMS for a more sleek, updated supply chain software option. This article from Logistics Management points to an increase in upgrading or moving to new software, mainly through SaaS based WMS: The usefulness of SaaS-based WMS systems expands beyond those small firms that lack capital resources for purchase-and-install implementations. In fact, Klappich sees SaaS delivery as a growth driver for the WMS market this year, noting that the offering is no longer limited to the “low end” of the marketplace. “It’s interesting to see how demand for SaaS has accelerated as more robust on-demand systems have been introduced to the market,” says Klappich. “It’s going to be interesting to see if this delivery method becomes a real option for larger, more complex facilities.” The article also explains why 2012 is likely to be the “year of the upgrade”, as many companies are looking at the choice between how to manage brick-and-mortar business and ebusiness supply chains.
