I would like to know about the best practices that you or others in your organization are following (or have followed in the past) that would encourage the usage of Ariba amongst all the users in various departments. Every organization (or atleast most of them) has at some point or the other made the switch from a "manual" process of spend management to an "electronic" one. When implimenting this,
1. What strategies have you implemented that ensured that most of the users in all the departments have felt comfortable working on the tool?
2. On an average, how much time did it take from when your org. has started implementing Ariba till you felt that it was fully utilized by all the users?
3. Which areas did you feel that it made more sense to stick to the manual process rather then making the switch to Ariba?
