We clarified more or less with the previous question.
I have another question and the answer to which I would like to see tips and comments
Some customer refuses to sign off requirements. What are you going to undertake?
In this situation I will contact with the customer and find out any obstacles. There are two possibilities: something wrong with requirements or person who has to sign it off.
If it is a right person and he or she has authority, proper involved in to the project, decisive and willing to let go the discovery stage of a project, I will explain unclear points in the document. I make the review requirements protocol in which
divide requirements on two parts: first can be approved by the customer and second on that client disagree. Maybe there will appear requirements which are not put in document but should be there which I put in the third part of the protocol.
If I have time, employ some discovery methods that foster an exhaustive approach. Brainstorming, requirements workshops, and other discovery methods that encourage lots of ideas and group creativity may help stakeholders, who generated requirements in the second part, to feel they are not overlooking anything important, they meet all goals of the project and signer agree with them. Improve the document on requirements which were changed in these activities and put new if necessary.
If I don't have time I show the review requirements protocol to my project manager to decide what should we do.
If it is a wrong person I have to find a right one.
