2225 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

Term Kind Topic What it is
Automated Accessibility Coverage metric Accessibility Testing The proportion of accessibility criteria a tool can decide mechanically — around a third — and the explicit acknowledgement that the rest needs people.
Change Failure Rate metric Quality Gates The proportion of deployments to production that cause a degradation requiring remediation.
Chaos Experiment Yield Findings per Engineer-Week, Resilience Discovery Rate metric Chaos as a Test New findings per unit of resilience-engineering effort - the number that separates a chaos programme's decaying discovery value from its cheap and permanent regression value, and decides which half to fund.
Contract Coverage Gap Contract Blind Spot, Unasserted Field Surface metric Consumer-Driven Contracts The share of a provider's response that a consumer's code reads but its contract never asserts on - the exact surface a provider can delete while every contract check stays green.
Mutation Score metric Mutation Testing The proportion of deliberately introduced faults that the test suite detects — a measure of whether tests would notice a defect, unlike coverage.
