What is bidirectional Traceability matrix briefly explain?
It is a traceability matrix which links the required testcases with their respective requirements as well as functional specs design spec. It is bidirectional because mostly it happens that instead of writing the actual requirements and functional specifications in the table we write the corresponding column no. and hyperlink it so you click on that and it will take you to the respective page and also that if any change has to be done in any document no need to change in the RTM.
