For a large global organization like Cloud Kicks (CK) rolling out a complex Salesforce release, the consultant should recommend conducting Train-the-trainer sessions. This approach involves training a select group of knowledgeable users (trainers) who will then train other users in their respective locations. This method ensures that training is consistent and can be tailored to local needs, making it more efficient and effective for large and geographically dispersed teams. Salesforce best practices highlight the importance of scalable and localized training for global implementations to ensure comprehensive user adoption and understanding.
