Non-functional Requirements on Web-Application

On the part of the IT persons responsible a survey with all necessary criteria concerning non-functional requirements e.g. client-system-requirements, service-hours, reaction-time, availability, data-amount, amount of users, etc. was assembled;
This survey considers the IT-point of view.

Because this survey focuses the technical aspects, it was translated into guidelines according to the wording of the department and the level of knowledge regarding IT.
The guidelines were added by a checklist, in order to offer a tool, which ensures the completeness.
