Inherited Technical Debt		Technical Debt received through merger, acquisition, outsourcing transition, system transfer, platform consolidation, provider dependency, or a change in ownership boundary.
Integration Debt		Technical Debt in interfaces, protocols, transformations, dependencies, data exchanges, adapters, or integration structures that create continuing coupling, fragility, cost, or constraint.
Intent		The classification describing whether Technical Debt is Intentional, Unintentional, Inherited, Emergent, or of Unknown origin.
Interest		The recurring or compounding burden created by continuing to retain Technical Debt, such as support effort, delivery friction, manual work, incidents, controls, or lost flexibility.
Knowledge Debt		Missing, outdated, inaccessible, unreliable, fragmented, or insufficiently structured knowledge that creates additional cost, difficulty, Risk, delay, or constraint.
Known Error		A diagnosed Problem with a documented root cause, workaround, or both.
Materiality		The governance significance of a Technical Debt Item, classified as Level 1 Local, Level 2 Significant, Level 3 Portfolio, or Level 4 Enterprise/Critical based on impact, Asset criticality, dependency reach, Risk, strategic constraint, duration, and other relevant factors.
Mitigation		Action that reduces the burden, likelihood, impact, exposure, or operational consequences of Technical Debt without fully eliminating the underlying condition.
Non-Functional Requirement	NFR	A measurable requirement describing how a Software System or Solution must perform or operate, including qualities such as Security, availability, resilience, performance, scalability, maintainability, supportability, interoperability, observability, recoverability, and compliance.
Obsolescence		The contextual condition in which an Asset, technology, component, process, interface, skill, or body of knowledge has become outdated, unsupported, unsuitable, or increasingly difficult to use.
Outcome Metric		A measure of whether Technical Debt remediation or governance reduced burden, Risk, cost, delay, incidents, support effort, strategic constraint, or recurrence.
Portfolio Governance		Governance that coordinates Technical Debt priorities, dependencies, shared funding, systemic conditions, and tradeoffs across multiple Assets.
