Early in your project, you are having a discussion with the sponsor about an estimating technique. You want a form of expert judgment, but the sponsor argues for analogous estimating. What would be the best course of action?
1) Continue with expert judgment as it is the most reliable technique.
2) Switch to analogous estimating as it is recommended by the sponsor.
3) Consider a combination of expert judgment and analogous estimating.
4) Seek advice from a project management professional.
