Dear All,

Can anybody please let me know the list of questions we can ask the customer related to interfaces while deriving the estimations.

We have a requirement where we need to submit the estimates for the interfaces which communicate with each other. We do not have any information for some of the interfaces but still we were asked to submit the estimations.

So. we would like to go back with list of questions for answers from the customer which in turn help us to estimate the effort.

Thank you.
