In recent years the sophistication and application of Warehouse Management Systems (WMS) has increased significantly and they are now seen as vital systems for gaining efficiency improvements and cost savings within the logistics industry. However, the successful implementation of a WMS is rare. Therefore, this study’s aims were to explore the key factors that influence the success of a WMS development project. Twenty two interviews were conducted with Directors, Senior Managers and Consultants that had been associated with WMS implementations. The findings show that there are conflicting views between Directors and Senior Managers with both groups focusing on different priorities during a WMS project. In addition, appointment of a project champion, frequently an external consultant is important in ensuring that there is good communication between all the stakeholder groups. The study concludes that many Directors need to develop their understanding of WMS development projects, in order to avoid becoming completely reliant on a consultant project champion who is always likely to leave the organisation at some point.
