Otsustustabelid, known in English as decision tables, are a tabular representation of business rules. They are used to document complex logic, especially when a decision depends on multiple conditions. Each row in a decision table represents a unique combination of conditions and the corresponding action to be taken. The table is divided into sections for conditions and actions. The condition entries specify the values or states that trigger a particular outcome, while the action entries indicate what should happen if those conditions are met.

Decision tables are valuable for clarity and completeness. They help identify all possible scenarios and prevent the omission of any rule. This systematic approach aids in the design and implementation of software, business processes, and policy documents. By presenting logic in a structured format, decision tables reduce ambiguity and facilitate communication among stakeholders. They are particularly useful in situations where the number of possible condition combinations is high, making a simple series of if-then-else statements cumbersome or difficult to manage. The process of creating a decision table often reveals inconsistencies or gaps in the existing logic.
