In traditional development projects, a support department is present that takes over responsibility for the software after it is implemented in production. Patches, changes, and so on are tested and rolled out by the support department. The supplier maintains the services, so the customer doesn’t need a support department for the maintenance of the service itself. Despite the savings that can be achieved, this poses a problem because test activities still need to be done with and around the service. It seems obvious that the test manager, as in the implementation phase, has this responsibility. In addition, it is important to determine whether the supplier keeps their promises with regard to nonfunctional attributes, such as availability and performance. Testing, the use of monitoring tools, and logging are the appointed measures.
