A strong Salesforce rollout starts long before admins build fields or developers write Apex. It starts with business goals, data quality, ownership, and a realistic implementation roadmap. Salesforce’s own guidance around migration and adoption points to preparation, cross-functional involvement, testing, and staged rollout as core success factors. Prosci’s change-management guidance supports the same idea: define the reason for change, identify affected processes, and manage adoption as part of the project, not after it.
