Term	Kind	Topic	What it is
Scenario-Based Comparison Concrete Scenario Evaluation, Cash Out the Qualities	practice	Trade-off Analysis Methods	Comparing design options against specific described situations rather than against abstract qualities - which forces vague terms to be cashed out and turns a discussion into a decision.
Sensitivity Analysis What-Would-Change-The-Answer Analysis	practice	Trade-off Analysis Methods	Identifying which assumption, if wrong, would change the decision - which tells you what to measure early and what to design to change cheaply.
Trade-off Analysis Methods	practice	Trade-off Analysis Methods	Structured ways to compare architectural options — valuable for making reasoning explicit, dangerous when they produce false precision.
Weighted Decision Matrix	practice	Trade-off Analysis Methods	A scoring method that rates options against weighted criteria, used to expose disagreement about priorities rather than to produce an answer.
