we used to do that a lot but mostly through interviewing many people (management as well but more real people).. asking what they do for a job, which department they work, how they work, what they think could be better to enhance their work, how they would like to work when they had the choice... what devices they use, where they work (home/office), how often the work remote, collaborations, sharing of files, etc etc..
if you ask 20 people these same questions.. the segmentation shows.
