Every project makes locally sensible decisions: this vendor, this interface, this workaround. Ten years later the organization is running dozens of systems that each made sense on their own and together make nothing easy. Interoperability becomes a fire drill, modernization becomes impossible to sequence and every new program starts with an integration project.
Architecture as a Service puts a single, enterprise-level point of view across all of those decisions. Not to slow them down, but to make sure each one leaves the organization better positioned for the next. It is the perspective a strong CIO or CTO would bring, offered as a service rather than a full-time hire, with the healthcare and standards depth that generalist IT leadership rarely has.
Three levels of perspective are available, individually or together.
