It is also called system design document. My role as a BA is just a mediator or a middle layer between business users and developers and we make developers to understand the business requirements.
What do understand by URS & FS ?
User requirement specifications and Functional specifications. To keep track of these requirements, we generally use Traceability matrix.
By using Test director we can do traceability of requirements n testing phase.
How do you prepare use cases?
BY using MS Visio and Rational rose.
How do you participate in testing as a BA?
I participate mainly in reviewing the test cases to see if all the requirements have been met.
What is the main quality of a good requirement?
