Nor is such a company productive when looked at from the outside.

Google might be a good example of this. Each team likely seems productive internally because they come up with new products quickly but customers wonder why the company is producing 4 different chat apps, 3 video services, and nothing seems to work together.

Google's multiple public facing apps that do the same thing are a unique issue. What's not unusual is for a company to have multiple internal tools, vendors, processes that are duplicative.
