The chair, who is suppose to be an advocate of the tenure candidate, should be the mouthpiece of the tenured faculty. Candidates do not always know what the important weights are but the chair can interpret those comments and weigh them properly. Diversity of opinion can be good because then the faculty have a more clear understanding. Some faculty complain they do not get adequate feedback. In cases where there is turnover it can hinder things.
Some departments have changes in chairs and that can cause confusion.
The more information you give a candidate the better that candidate can establish what needs to be done. During spring 1998 the Senate passed a motion allowing the use of supplemental retirement funds to be put into three different mutual funds. It is not yet possible to do that.
