By asking the Service Delivery organizations (to be) involved in the delivery of services to the Client to confirm they will be able to deliver the services as described in the Service Supply Forecast, the Engagement Manager assures the organization is informed while giving the organizational units also the ability to indicate potential risks. Such risks must be validated and if necessary mitigating actions should already be identified and initiated. It is deemed best practice if the Service Supply Forecast, if necessary consolidated with the Service Supply Forecast of other Service Engagements, is discussed in the internal Change Advisory Boards of the delivery units.
