The columns in a decision table represent the combinations of conditions or rules of a business decision, which will result in a certain action depending on the input.
What are the uses of decision table?
A decision table is an excellent tool to use in both testing and requirements management. Essentially it is a structured exercise to formulate requirements when dealing with complex business rules. Decision tables are used to model complicated logic.
What is decision table with example?
A decision table is a scheduled rule logic entry, in table format, that consists of conditions, represented in the row and column headings, and actions, represented as the intersection points of the conditional cases in the table. Decision tables are best suited for business rules that have multiple conditions.

What is decision tree and decision table explain with example?
Decision Table is just a tabular representation of all conditions and actions….Difference between Decision Table and Decision Tree :
S.No. | Decision Table | Decision Tree |
---|---|---|
6. | It is used for simple logic only. | It can be used for complex logic as well. |
7. | It is constructed of rows and tables. | It is constructed of branches and nodes. |
How do you read a decision table?
A Decision Table is read vertically, with each single column defining a single decision rule….So if you are reading the Decision Rule 1 column above, it would be read as:
