I was being a bit tongue-in-cheek because "digital transformation" has become an overused marketing term. But I think the core of it is valid -- a company has an inefficient process due to lack of technical expertise or whatever and you help them fix it.

There's multiple parts to this field of work: networking to find leads, doing discovery to understand a potential client's problem, formulating a technical solution, creating/negotiating contracts, and implementing the solution. My experience in this area was at a company that was large enough so that these pieces were split into different roles within our organization, and I was mostly on the tech/solution implementation side.
