unfortunately this is a common situation for most of the projects ,as a project manager you need to fill in the gaps and try to maximize your team usage to get all information that are needed ,and fill in the information you cannot get from customer based on your experience along with your team ,the less information you have the more reserve you will plan to accommodate such rick
