Hi Tack
I would initially focus on two main aspects to retain talent during change management.
First (as you also said) given the limited knowledge of the target company’s personnel from the due diligence stage, it’s crucial to prioritize Key Roles, by identifying positions that are essential for the success of the integration and quickly building relationships with key personnel to understand their concerns and motivations. This can help tailor retention strategies effectively.
Second, retention incentives, which means on one side financial incentives such as retention bonuses to key employees to encourage them to stay through the transition period and on the other side clear career development opportunities within the new organization. Highlight potential for growth and advancement.
Very practical approach, but in my experience useful for avoiding unwanted exits.
