Answer / anoop wilson
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

Answer / vijayakumar g s
I feel the response from Wilson is the valid response. Any
road is bidirectional unless you prevent one direction by
putting a "NO Entry" board for one direction - meaning
tracing from requirements to code to test automatically
establishes trace from test to code to requirements , isn't
it?
Hence Horizontal & Vertical traceability is the correct
interpretation.
Unfortunately more than 95% of people who know CMMI and do
CMMI training dont know it correctly.

Answer / kamalnath
As posted by Anoop, Bidirectional traceability includes Horizontal and Vertical traceability. But the definition of both these is as follows.
Vertical Traceability: This is the traceability of work products from Requirements -> Design -> Code file -> Test cases
Hirozontal Traceability: This is the dependancy between the requirements. i.e this linkage will show is when there is a change in one requirement, how it affects other requirements in the list

Answer / shiva
when requirements are traced to test cases and vice versa
it is called bidirectional traceability.
any suggestions welcome
