## A–C

- **Asset** - an individually tracked piece of equipment. Lives in both hierarchies: location (where) and system (what). [Details](/docs/asset-management/assets)
- **Asset type** - the catalog entry describing what kind of equipment an asset is; carries defaults like useful life.
- **Assessment (condition)** - a dated, sourced condition rating on an asset. [Details](/docs/asset-management/condition-assessments)
- **Change order** - a recorded scope/cost change against a project budget. [Details](/docs/projects/budgets-and-financials)
- **CMMS** - computerized maintenance management system; AssetLab's operations layer. [Overview](/docs/cmms)
- **CoF / LoF** - consequence of failure / likelihood of failure; the two factors in risk scoring. [Details](/docs/asset-management/risk-and-fci)
- **Compliance item / record** - a recurring regulatory obligation, and one dated fulfillment of it. [Details](/docs/cmms/compliance)
- **Corridor** - a cross-network bundle of infrastructure features sharing an alignment (road + main + sidewalk). [Details](/docs/infrastructure/zones-routes-corridors)
- **Cost snapshot** - a frozen point-in-time capture of a project's financial state. [Details](/docs/projects/budgets-and-financials)

## D–L

- **Feature** - one real piece of infrastructure (a pipe segment, a hydrant). The linear-asset counterpart of an asset. [Details](/docs/infrastructure/features)
- **Feature class** - the kind of infrastructure a feature is; carries geometry type, unit rate, useful life, attribute schema. [Details](/docs/infrastructure/networks-and-classes)
- **FCI** - facility condition index: deficiency cost ÷ replacement value. Lower is better. [Details](/docs/asset-management/risk-and-fci)
- **Form template / response** - a reusable inspection/checklist definition, and one filled-out instance attached to work. [Details](/docs/cmms/forms-and-inspections)
- **Location** - a room/floor/zone within a building; the finest grain of the location hierarchy. [Details](/docs/asset-management/locations)
- **LoS (level of service)** - measurable service commitments, tracked as measures against targets. [Details](/docs/infrastructure/level-of-service)

## M–R

- **MCP** - Model Context Protocol; how AI assistants connect to AssetLab. [Overview](/docs/ai)
- **Milestone** - a dated, duration-less marker in a project schedule; carries external commitments. [Details](/docs/projects/tasks-and-milestones)
- **Network** - a top-level infrastructure container (Roads, Water Distribution…). [Details](/docs/infrastructure/networks-and-classes)
- **Organization** - your tenant: the boundary all data, users, and keys live inside. [Details](/docs/start/core-concepts)
- **PM schedule / template** - a recurring maintenance definition that generates work orders / its reusable, unbound blueprint. [Details](/docs/cmms/preventive-maintenance)
- **Replacement planner** - scenario modeling over asset lifecycles: what to replace, when, under what budget. [Details](/docs/projects/replacement-planner)
- **Requester** - the portal-only role for people who report problems. [Details](/docs/cmms/requester-portal)
- **Route** - an ordered sequence of road segments for programmed work. [Details](/docs/infrastructure/zones-routes-corridors)

## S–Z

- **Scope (API)** - a permission on an API key, e.g. `assets:read`. [List](/docs/reference/scopes)
- **Service area** - a domain of service delivery for LoS tracking (Winter Roads, Drinking Water). [Details](/docs/infrastructure/level-of-service)
- **Site / Building** - the top two levels of the location hierarchy. [Details](/docs/asset-management/locations)
- **System class / group / system** - the three levels of the classification hierarchy, Uniformat-aligned. [Details](/docs/asset-management/classifications)
- **TCO (total cost of ownership)** - an asset's full lifetime cost: acquisition plus every O&M dollar, built from its cost history. [Details](/docs/cmms/expenses-and-costs)
- **Uniformat** - the CSI/ASTM standard for classifying building elements; AssetLab's default classification skeleton.
- **Useful life** - expected service life in years; with install date, drives lifecycle forecasting.
- **Work order** - one unit of executable work against asset(s), location(s), system(s), or infrastructure feature(s). [Details](/docs/cmms/work-orders)
- **Work request** - a reported, not-yet-vetted problem; converts into a work order. [Details](/docs/cmms/work-requests)
- **Zone** - a geographic area (ward, district) that features fall inside. [Details](/docs/infrastructure/zones-routes-corridors)
