Our business changes so rapidly that we are forever adding business units, acquiring, divesting, resizing. The ERP people are years behind us all of the time.
What should we do in the mean time with our new group of companies we just acquired? Wait for the IT people?
We don't have that problem, our ERP team can keep up. Perhaps that is because our rate of acquiring and divesting is maybe 2 or 3 cases per year. We are only active in a couple of countries per BU in the cases I write about, so that makes it easier as well.
On the other hand, if the ERP team isn't capable of producing the rate of change needed to support the business requirements, I really hope that you get that sorted since that is practically the entire reason an ERP team exists.
We do deploy changes (technical changes) about 200 times each day, of which the teams dealing directly with business workflows do about 60 (including some stock, pricing and WSSI teams). It's not a lot, but it allows us to have nearly no lag time between business needs and implementation delivery. It did take a while to get to that rate, and a 2-week feature freeze one time to shift all processes to a model that allows for this change rate. But it works well for us. (and reporting, visualisation, ETL, and ML are all done without spreadsheets for about 3 years now)
As for why we did that (in case that was a question you'd be asking since it is obviously not a change that costs nothing): we no longer wanted to accept the risk of doing it the old way, we also didn't want to have as much onboarding friction due to having many diverse sub-workflows inside teams, because even if you did learn about what someone DIY'ed in your local team, you will still run into the same problem ad-hoc when dealing with other teams, usually at the worst possible time. Same goes for off-boarding, we don't want to spend months trying to figure out what custom stuff someone put in place, especially since you get non-engineering solutions to engineering problems (the excel shaped one) but also engineering solutions to non-engineering problems (the python notebook one). We want our people to be able to spend as much of their time on the actual work instead of side quests that don't add the value we are looking for. It doesn't mean exploration or experiments are banned, but it does mean we want to facilitate as much as we can so you don't have to do anything extra by default.
I'm guessing your company is somewhat more homogeneous than us conglomerates?
Edit: no it is not an ERP problem. It is a people problem. The team simply can't scope out the new factories quickly enough before the business changes something. Often the newly acquired factory has a different costing method for instance, and lots of data has to be collected before they can go on the master ERP. This may involve, for instance, timing every products build, collating and verifying it (in Excel probably), before the implementation can progress. This can take months. Especially when.... three main priority is selling stuff, rather than having neat BI
