conditionsrequirements

Conditionsrequirements is a term used to describe requirements whose applicability depends on specified conditions or states. In practice, it refers to conditional or gated requirements, where a given requirement only applies when certain criteria are met.

These requirements are typically expressed with an antecedent (the condition) and a consequent (the requirement). For example, a conditional requirement might state: if the user is authenticated and has the admin role, then audit logging must be enabled. Such constructs are common in software engineering, systems engineering, and product management to model behavior that varies by context.

Specification methods for conditionsrequirements include if-then statements, decision tables, and use-case scenarios. Clear traceability is important: stakeholders should be able to connect each condition to the corresponding requirement and verify that both the trigger and the outcome are testable.

Challenges include ambiguity in defining conditions, conflicting triggers, and changing criteria over the project lifecycle. Misstated or overlapping conditions can lead to scope creep or gaps in coverage. Testing must address both the condition and the effect of the requirement when the condition holds, as well as the default behavior when it does not.

Related concepts include prerequisites, gating criteria, feature toggles, and conditional logic. In practice, effectively managing conditionsrequirements improves clarity around when and why particular capabilities are needed, helping align stakeholders and support regulatory, architectural, or user-context needs.
