i did not survive many schools. i went to 4.
my bachelors required a dissertation, which i think was my most useful piece of work. my masters was called a thesis, had to be in type hard copy and carbons, and exposed me to xrays that have given me cancers. my ph.d. was called a thesis, was chosen and directed by my "advisor" . i did the lab part of a large project. i did not know what the hell the whole thing (big picture) was about. this project had half a dozen phd candidates doing exacting stuff. was very multidisciplinary. the lab work was just a pain in the .... the project needed really good lab people, and passed out phd's for performing miracles. the real problem to degree was passing the qualifiers.
i never heard of a phd in management, but i do not read the offers from on the line schools.
