Abstract
Functional and performance requirements can be made at different levels in an organization. Functional requirements are often made because we cannot process large quantities manually if we want to achieve certain elapsed times or because we are never able to get information that quickly. This is one of the reasons why we invest in IT support. This requires choosing infrastructures and applications. That is how we came to work with personal productivity tools. That is how our business processes happen to be supported by SAP these days and also how we got an internet channel. We demand our IT to be adaptable, we need it 24 hours a day/7 days a week and the costs have to be calculable.
