It is probably not what you intended, but this is how it sounds like: we have a hundred micro-teams of 2 working in silo on low-coupling microservices and we don't have the luxury of coordinating an end to end design.
Edit: 2 questions were asked, too deep to reply.
1. You said 250 people, nothing about IT. Based on the info provided, this was the image reflected.
2. "the luxury of coordinating a monolith". Done well, it is not much more complicated that coordinating the design of microservices, some can argue it is the same effort.
