ConditionDecision

ConditionDecision is a conceptual construct used to model a point in which the chosen outcome depends on evaluating a set of conditions. It is used in decision modeling, software design, and automation workflows to centralize logic that selects among alternatives based on predicates.

Typically, a ConditionDecision consists of a list of condition–outcome pairs and an optional default outcome. Each condition is a boolean expression, and when evaluated, the associated outcome is selected. Depending on the design, conditions may be checked in a fixed order or by defined priority, with the first satisfied condition triggering its branch. If no condition matches, a default branch provides a fallback action.

In relation to other concepts, ConditionDecision overlaps with if-else chains, switch statements, and decision nodes in workflow engines. In graphical modeling, it corresponds to a decision node or gateway, and in software design it aligns with conditional branching and rule-based systems.

Applications for ConditionDecision include business rule engines, access control, feature flags, pricing or eligibility rules, and AI planning where outcomes depend on user attributes, states, or environmental variables. It supports modularity and readability by separating condition logic from other parts of a system.

Advantages of using a ConditionDecision approach include improved clarity, easier testing and auditing of decision logic, and better maintainability when rules evolve. Limitations include potential complexity as the number of conditions grows, the possibility of overlapping conditions causing ambiguity, and performance concerns if conditions are evaluated sequentially without optimization.
