We already covered the proposed general usage scenario and particular use cases of a Brainstorming system. In order to evaluate their implementation, in this section the application requirements will be presented. They are split into functional and non-functional ones. The first refers to all the features needed to be implemented, while the second category refers to performance, extensibility and scalability of the system.
Functional requirements

| FR.1 | The system will allow multiple users to interact with the system simultaneously |
| FR.2 | The system will allow multiple devices to interact with the Microsoft Surface simultaneously |
| FR.3 | The users will be able to send ideas to the tabletop using mobile clients |
| FR.4 | The users will be able to generate and input ideas in the system |
| FR.5 | The Contributors will be able to input Brainstorming items directly on the tabletop |
| FR.6 | The Contributors will be able to Group Brainstorming items |
| FR.7 | The Contributors will be able to Edit Brainstorming items |
| FR.8 | The Contributors will be able to Relate Brainstorming items |
| FR.9 | The Contributors will be able to Print Screen |
| FR.10 | The Contributors will be able to promote Twitter or Flickr items to Brainstorming items |
| FR.11 | The Session Master will be able to login into its BSCW account |
| FR.12 | The Session Master will be able to Save a Brainstorming Session |
| FR.13 | The Session Master will be able to Load a Brainstorming Session |
