Ability to trace both backward and forward
* When requirements can be traced by code and code can be
traced by requirement
* Done througtout the development process
* To ensure that all the requirements are implemented in
the system
Agreed but the definition of Bi-directional Traceability is
that both vertical and Horizontal traceability is
maintained.
Horizontal Traceability is the traceability of requiremenst
across all the development phases Req-> Design->Module Spec-
>Unit Testing-> Module testing->Integration testing->
Systems testing
Vertical traceability is the traceability of the
requirements across modules or other requirements in the
product.This may not apply to all project / products
because this requiremenst was an outcome of having large
projects such as the ones executed by NASA and US Military.
Rashmi - i think you need to relook at the definition
