What tips help with a successful Salesforce implementation?

The most important Salesforce implementation tips: (1) start simple — configure only what you need on day one, (2) invest in user training before go-live, (3) designate an internal champion who owns the system, (4) clean your data before migrating, (5) define your pipeline stages before building. Most failed Salesforce implementations stem from over-customization before users are even comfortable with basics.
