Term	Kind	Topic	What it is
Debt Interest Rate Cost Per Unit Time, Debt Triage Axis	concept	Technical Debt	How much a piece of technical debt costs per unit time in slowed delivery, incidents and effort - which, paired with the cost to fix, is what separates debt worth paying down from debt that merely looks unpleasant.
Debt Register	practice	Technical Debt	A maintained record of known technical compromises with their cost, impact and repayment trigger, making debt manageable rather than merely felt.
LinkedIn Project Inversion: Stopping to Fix the Road Inversion	case-study	Technical Debt	LinkedIn halted feature development for roughly two months to rebuild its deployment and development infrastructure, because the tooling had become the constraint on everything.
Technical Debt Quadrants	concept	Technical Debt	Distinguishing debt by whether it was taken deliberately or inadvertently, and prudently or recklessly, since the four kinds need different responses.
