I absolutely advocate for a dedicated team, but I would also advocate for external collaboration (external resources) as part of it, versus having this team be composed fully of internal resources. Each M&A has its unique challenges, and even though having past knowledge of challenges and successful efforts is key, so is having a fresh pair of expert eyes helping a company plan and execute all PMI efforts. In my experience, using internal resources only can be detrimental to agility, creativity and flexibility.
