TCO Total Cost of Ownership — the full cost of buying and running an asset over its entire life. Purchase price is just the tip of the iceberg.
CMMS Computerized Maintenance Management System — the software where maintenance records, repair history, and spare parts data live. This is where hidden costs hide.
MTBF / MTTR Mean Time Between Failures / Mean Time to Repair — measures how often equipment breaks and how long it takes to fix. Directly drives downtime cost.
SLA Service Level Agreement — the part of a contract that spells out what happens when things go wrong. Uptime guarantees with financial penalties live here.
Sensitivity Analysis Testing "what if" scenarios — what if energy prices jump 30%? What if the asset runs 12 years instead of 8? Shows which supplier wins under different futures.
RFQ Request for Quotation — the document you send to suppliers asking them to bid. Building the TCO taxonomy before the RFQ is what makes this framework work.
