Analysis is the key factor which drives in any planning.During the analysis, the analyst understands the following:
-Verify that each requirement is tagged in a manner that allows correlation of the tests for that requirement tself.(Establish Test Tracibility)
-Verify traceability of the software requirements to system requirements.
-Inspect for contradictory requirements.
-Inspect for ambiguous requirements.
-Check to make sure that each requirement ,as well the specification as a whole, is understandable.
-Identify one or more measurement ,demonstration or analysis method that may be used to verify the requirement's implementation(during the formal testing).
-Create a test "sketch" that includes the tentative approach and indicates the test's objectives.

During QA Analysis the required documents will be carefully studied by the QA team, and the final Analysis
Report is documented.
The following documents would be usually referred:
1.Software Requirements Specification
2.Functional Specification
3.Architecture Document
4.Use Case Document
