Finally, to create a solid foundation for further PSS development within the consortium, an analysis of the main consortium members' customer is presented. The user activity cycle (UAC) is a tool used to identify customer needs and new business opportunities. A UAC puts the customer in the centre and focuses on the activities connected to the use of a product or service. The UAC is divided into PRE, DURING, and POST phases.

The following challenges/needs are not divided into different customer types, since some transcend these lines and others are independent of them.
