Bring your suppliers into your projects—Managing the design of work packages in product development

Early supplier involvement and integration is important in product development on strategic as well as on operational, project and team levels. Saab Aerospace intended to achieve early supplier involvement and high level of integration on all levels in the redesign of the aircraft JAS 39 Gripen. The research underlying this article shows that the intended strategy was only achieved on the strategic level and not on the operational project and team levels. One major reason for this was that the design of the work breakdown structure (WBS) and work packages (WP) in the product development followed the functional and departmental logic within each company resulting in incompatible structures and preventing communication and information exchange. This article intends to explore how prevailing functionally designed WBS and WP structures created barriers and to demonstrate how supplier integration can be improved by designing collaborative WBS and integrated WP. The Dependence Structure Matrix (DSM) is introduced in order to analyze, visualize and manage interdependencies and information exchange between Saab Aerospace and its supplier on different levels of the WBS and in different phases of the development process, following the logic of interdependencies and information flow, in order to support a strategy focusing on integration of suppliers on the project and team level.
