What do you do when leadership asks you to commit to a date?

Commitments are not fun.

It's a constant struggle between those executives and stakeholders who are trying to run the business and the product team that is understandably reluctant to commit to dates and deliverables - Marty Cagan

It's hard to make commitments without proper discovery. Product discovery is crucial to validate the ideas with customers and ensure there is value, usability, feasibility and viability. If not, you make decisions too early before knowing if the solution can solve the intended business problem.
