Suppose IF YOU HAVE BEEN GIVEN THE RESPONSIBILITY TO ELICIT REQUIREMENTS FROM A CUSTOMER WHO TELL YOU HE IS TOO BUSY TO MEET WITH YOU. WHAT SHOULD YOU DO?

⟩ Suppose IF YOU HAVE BEEN GIVEN THE RESPONSIBILITY TO ELICIT REQUIREMENTS FROM A CUSTOMER WHO TELL YOU HE IS TOO BUSY TO MEET WITH YOU. WHAT SHOULD YOU DO?

Create a questionaire and try to get as much information from the customer as possible.But be sure to make the questionarie more objective rather than subjective.

based on this questionaire have another set of questions formulated in continuation to answers provided to the first questioanire, this way you can make your understanding more concrete on the requirments and get what you are looking for in a few iterations of requestioning.
