I really liked Joan’s response.
“I believe the most efficient way is to have the department leader (VP/Director) lead the integration, and use this as an opportunity for leadership development for those directly under the VP/Director. Promote one to assist VP or Assistant Director and allow them to run the business as usual.” My add would be for the two to have daily briefs and provide weekly communication related to integration and business as usual – showing joint collaboration and communication that both activities are essential.
Thank you, Cindy
