"Management [...] wants something that works and delivers economic value for customers and will help them continue to innovate and deliver EVA for them in the future."

You're confusing "owner" with "manager". Most managers just want to get promoted, which usually means increasing their HC/budget, making sure credit for a project's success is their's, failures are blamed on others, getting trendy internal projects, doing endless re-orgs (knowing they'll move on before any true costs/benefits are realized), etc. "Economic value for customers" is an afterthought at best.

(Speaking as a former very-large-company manager.)

I'm not confusing owner with manager - I'm thinking of things through the lens of the principal-agent relationship and of upper management's goals (which was what the OP was talking about) rather the middle management's.
