This sounds like a really interesting role to be in, and one advantage is that you have visibility of both delivery and change conversations in one place. In a few merger and integration assignments I've worked on, I've usually adapted and layered change management tools and templates onto the existing PMO framework of the acquiring organization. When one person is covering both project and change responsibilities, getting early agreement on scope, roles and responsibilities, and governance makes a big difference in keeping things organized as the integration progresses.
I agree with Ama's suggestion about starting with a high level view of the future operating model. It does not need to be overly detailed at the beginning, but having clarity around the intended structure, core processes and key technology platforms helps anchor the work. From there, a light current versus future gap assessment with each business area can help surface the main changes that need to happen across process, systems, structure or policy.
Those gaps can then feed into a simple change intake pipeline or register. What has worked well for me is keeping the intake information straightforward so it is easy for business stakeholders to engage with. Typically this includes a short description of the change, the business function or capability impacted, the type of change, the level of impact, any known dependencies and a proposed owner. That register then becomes the central place to scope, prioritize and track changes as they move through implementation.
In practice, the templates that work best tend to be the ones stakeholders already recognize. Reusing existing organizational artefacts, templates and language where possible usually helps adoption and avoids introducing something that feels too new or complex. The approach can also vary depending on the type of merger, particularly whether systems and processes will be fully integrated or whether parts of the organization will continue operating more independently.
One practical approach is to use existing current state processes and workflows and map them to the proposed future state. From there, you can capture people, process and technology impacts across business units or departments. Frameworks such as the APQC Process Classification Framework ( https://www.apqc.org/process-frameworks ) can also be useful as a reference point when structuring process related change artefacts.
I am fairly new to this community myself, so I am not sure if there are shared templates within the forum. There are a number of publicly available examples that can be a good starting point though. Hope this helps.
