They probably do, but with how expansive they are, the massive variety of acquisitions, and not being clairvoyant, it’s gotta be like herding cats.

I’ve worked in tech companies (systems management, telecom, etc) and in conventional businesses (manufacturing, distributing, production, reselling, banking, etc).

The arch teams in conventional business are more structured, formalized, as their remit is to ensure infrastructure is stable, predictable, and to practically eliminate risk.

The tech companies have arch teams whose focus is interoperability between business units, high communication, maximize utilization, etc. Risk is still a concern, but it’s not primary (unless you fuck up). Tech orgs are about flexibility.
