Integration manager involvement in DD

Hi all,
I am interested to hear how you involve your integration managers in the acquisition process (pre-closing). In our company we don’t have a dedicated integration team but we rather identify integration managers for each acquisition separately. This person is then typically the PMO manager during the acquisition process which ensures that he is at the very center of all discussions in the due diligence and is well-aware of all findings and considerations. This way we avoid having to hand over the responsibility post closing to someone who has not yet been involved. Interested in your thoughts!
