Once the functional requirements have been identified and defined, the requirements should be recorded in the design documentation as part of the conceptual design. There are a number of formats that can be used, such as bulleted lists and numbered lists, but a simple table works well. Assigning an ID to each requirement makes it easier to reference the requirement later in the design document:
|
ID |
Requirement |
|
R001 |
Consolidate the existing 100 physical application servers down to five servers |
|
R002 |
Provide capacity to support growth for 25 additional application servers over the next 5 years |
|
R003 |
Server hardware maintenance should not affect application uptime |
|
R004 |
Provide N+2 redundancy to support a hardware failure during normal and maintenance operations |
