How can I examine the replies from our employee questionnaire to detect {shared topics/worries} and regions that need enhancement? We obtained a considerable amount of input, and wish to confirm that we're employing it efficiently to execute significant modifications. Concretely, we are curious about the response of {a particular group/division} to the questionnaire, and if there are any {distinct patterns/changes} we should be mindful of.
