I need to know the different situations when can I use equivalence partitioning technique and when to use decision table technique. A lot of situation I feel that I can use equivalence partitioning instead of decision table and vice versa. In the example below (I got it from guru site). Decision table technique is used, my question we don't use equivalence partitioning?. Please advice
