I agree with your comment Candis; however, one can not always be bound by a schedule.  As a manager, issues arrise at a moments notice and must be addressed.  Leadership must be flexible in order to get task completed. 

While I agree with your comment I also feel that by prioritizing your time and setting a schedule are also very important for any level of the team during your workday. 

both are a very intergal part of any effective team
