I agree having an integration team that is dedicated to the integration process is critical in order to allow BAU to occur and be managed by a different team. However you will need support and presence from the executive level on the integration team in order to demonstrate to the organization the seriousness and importance of the integration. The make-up of the integration team may benefit from a mixture of SMEs within the organization, executives as mentioned and third-party consultants that can bring an unbiased approach and not be seen as a threat to the employees and teams that are not involved in the integration process.
