comprises the business units Combitech, Avionics Systems, Aerostructures, Traffic Management, Vricon as well as the development of product ideas that fall outside of Saab's core business. The business units within Industrial Products and Services differ from Saab's other operations by their focus on business-to-business (B2B) customers or because they are not dependent on Saab's principal end-customers. Other business areas within Saab have a customer base largely consisting of public authorities. With different customer groups come different management strategies and priorities. Opportunities to strengthen these operations in the long term are greater in the new organisation. Industrial Products and Services will work with individual growth strategies for each business unit. Support and Services Support and Services offer maintenance, integrated support solutions, field facilities, logistics and regional aircraft maintenance.
