The client context and real world problem determine the nature of the model, and the modelling process must be consistent with the clients' skills, capabilities, and goals. The purpose is to help the clients solve their problem. If the clients perceive your model does not address their concerns or lose confidence in it, you will have little impact. Focus your modeling work on the problems that keep the clients up at night.
