Term	Kind	Topic	What it is
Cost Driver Scaling Driver, Cost Dimension	concept	Architecture Cost Modelling	The measurable quantity whose growth causes a cost to grow - identifying it correctly is what makes a cost model predictive rather than descriptive.
Cost Model Sensitivity	practice	Architecture Cost Modelling	Identifying which assumptions in a cost projection dominate the outcome, so effort goes into the estimates that actually matter.
Dual-Run Cost Overlap Migration Cost Hump, Parallel-Running Overlap	concept	Architecture Cost Modelling	The period in any platform migration when both the old and the new system are paid for at once, which raises the run rate before it falls and sets the true date on which a cost business case begins to pay back.
