We actually do capacity planning in dollars to this day, and did do queuing models of both batch and multi-core, multi-machine transaction processing.
For example, businesses in HR might have metrics like average case correspondence count, open rate per day, idle status, etc. The dev team would commit to certain of these metrics, and optimize both costs and these meteics. This, to me, would signal an IT organization with high status (autonomy delegated to tech leaders).
Whereas a different company might have IT committed to X TPS without the ownership of business metrics
The simple fact that a large company is able to liquefy a non-linear large-blocks market into dollar amounts that you can measure, is the ultimate dream of any 1800 economist.
