1. A method of distinguishing a business rule from a non-business rule in a computer program, the method comprising the steps of: a computer identifying a first rule in the computer program based on a conditional statement within the first rule; the computer determining whether the first rule performs underlying operation of the program independent of a business function of the program; the computer searching the first rule for a key word which indicates part of a business transaction with a customer of a business using the computer program; the computer searching metadata of the first rule for a key word which indicates part of a business transaction with a customer of the business; the computer determining whether a sequence of program steps in the first rule matches a predetermined sequence of program steps indicative of a business rule or whether the sequence of program steps in the first rule matches a predetermined sequence of program steps indicative of underlying operation of the program independent of the business function of the program; and based on both determining steps and both searching steps, the computer determining if the first rule is a business rule.
