Requirements Management

Requirements Management: - 

Requirements management is a set of activities that help the project team to identify, control, and track 

requirements and changes to requirements at any time as the project proceeds 

Once requirements have been identified, traceability tables are developed. Shown schematically in Figureure, 

each traceability table relates identified requirements to one or more aspects of the system or its environment. 

Among many possible traceability tables are the following: 

 Features traceability table. Shows how requirements relate to important customer observable 

system/product features. 

 Source traceability table. Identifies the source of each requirement 

 Dependency traceability table. Indicates how requirements are related to one another. 

 Subsystem traceability table. Categorizes requirements by the subsystem(s) that they govern.

 Interface traceability table. Shows how requirements relate to both internal and external system 

interfaces. 

In many cases, these traceability tables are maintained as part of a requirements database so that they may be 

quickly searched to understand how a change in one requirement will affect different aspects of the system to 

be built. 

TRACEABILITY:

Traceability is a property of an element of documentation or code that indicates the degree to which it can be 

traced to its origin or "reason for being". Traceability also indicates the ability to establish a predecessor-

successor relationship between one work product and another. 

 A work product is said to be traceable if it can be proved that it complies with its specification. For example, a 

software design is said to be traceable if it satisfies all the requirements stated in the software requirements 

specification. Examples of traceability include: 

 External source to system requirements 

 System requirements to software requirements 

 Software requirements to high level design 

 High level design to detailed design 

 Detailed design to code 

 Software requirement to test case.
