You may wish to rephrase as follows: As you probably know....(then state the thing you suspect they do not know) Use the language of suggestion: You may wish to consider... I understand that other organizations have had this issue and what some of them have done is... How have you solved this problem? (implies they have already solved all the problems) With your experience and knowledge in this area.... Your role is.... My role is... (establishing different yet equal roles)
