Decision tables in Pega are ideal for situations where you need to apply multiple conditions to arrive at a decision. They are best used when you have a limited number of conditions and actions that result in a discrete set of outcomes.
B . A dance studio recommending a membership type based on the number and type of dance classes is suitable for a decision table. The number and type of classes can be mapped to specific membership types in a table format where each row represents a possible scenario and outcome.
D . A hair care company suggesting a line of products based on various attributes such as hair type, scalp moisture, hair moisture, and whether it is color-treated is also suitable for a decision table. Each combination of attributes can correspond to a specific product recommendation, making a decision table an efficient way to handle these rules.
