In which phase of the software development process would probing questions be used to verify the problem definition?

Analysis Phase

Explanation:

The Analysis Phase is where the project lifecycle begins. The Analysis Phase is where deliverables are broken down. The Analysis Phase is also the part of the project where the overall direction that the project will take through is identified. Also, in the Analysis Phase requirements are gathered. Gathering requirements in this phase involves probing users to know what they need and how they desire the system to function.
