I have read a number of books on thesis writing that recommend signposting. I like it as it gives the reader an idea of where you are going. I used this method in my draft chapter introductions. However, in the feedbacks I got, one of my supervisors advised against it saying the introductory sections of the chapters shouldn't contain what appears to be conclusions. My principal supervisor made no comment on the point. I like to stick to the method, but at the same time I feel reluctant disregarding the advice out of deference to my supervisor. What do you guys think.
