1 - Mentors in the team
Should all members of the BPM team be considered as possible "mentors"?
Note that this is talking specifically about your selected project, not about a generic process in a company.
2 - Mentees in the organization
Who within the organization would be the "mentee(s)" for the institutionalization of the new processes?
3 - Shadowing
Identify ways in which mentors and mentees can use "shadowing" as a method for tracking and assessing the changes within the company after completion of the BPM project.
