Many organizations don’t have central Integration teams but use ad hoc teams from the acquiring business unit. Is there a benefit to this (ad hoc team doing it for the first time each time) vs having a central team (doing it all the time) in place?
I think a hybrid approach is the best approach. If the company is a serial acquirer (or wants to become one), it’s best practice to build an internal knowledge base (central team), but then leverage the teams closest to the business to ensure that you’re capturing any process or operational nuances that could derail the integration. Building a playbook library for each functional area and business process also helps first-timers get up to speed on the methodology and expectations.
