Explanation
User contest and post go-live recap are two communication examples that the consultant can recommend to send after implementation. User contest is a type of communication that encourages users to participate in a competition or a challenge related to using Salesforce, such as completing a certain number of tasks, earning badges on Trailhead, or submitting feedback or ideas. User contest can help increase user engagement, adoption, and satisfaction with Salesforce. Post go-live recap is a type of communication that summarizes the results and outcomes of the implementation project, such as key achievements, lessons learned, success stories, or next steps. Post go-live recap can help celebrate the project completion, acknowledge the project team and stakeholders, and provide guidance for future improvements. Teaser email and project sponsor profile are two communication examples that the consultant can recommend to send before implementation.
