Although completing a story may require contribution from people in different roles - QA analyst and developer and experience designer, for example - each person is still responsible for the entire outcome of the story. An Agile story is an expression of end-to-end business need. Good managers know how to work the problem and solution space.

Basis path testing in software testing is a white box method where the tester examines the codebase to identify all possible paths that could be taken by the user to achieve their aims. These paths are then written as test cases to ensure all the different identified scenarios in the main branches are covered.
