1. SENA’s RE-Needs
0. Project Scheduling as a method to avoid time overruns

Realistic project scheduling can be used to avoid time overruns. SENA would like to know more about how requirment analysis can be integrated into the project schedule and managed in order to avoid introduction time-consuming new requirments during implementation.

1. Relationship between requirements, architecture, implementation, and project cost in bespoke applications

Often small changes in the requirements can have significant effects in project cost, and thus its financial viability. How can such changes be discovered, negotiated, and managed?

2. Non-Functional Requirements specifications in the area of multi-user client-server systems

Multi-user client-server systems often implicitly contain a number of non-functional requirements in the areas of response time, security, safety, portability, and trustworthiness. How can such requirments be elicited and expressed?

3. Meta requirements

SENA often undertakes formal studies in order to create requirement specifications. How can specifications for such studies be expressed?

4. Conflict resolution

During requirement elicitation a number of parties with different interests produce conflicting requirements. This creates conflicts which hinder progress. SENA would be interested in advice for handling such cases.

5. Use of the Internet
