The WonderCard, Ultd. credit card operations division has revised the criteria for granting credit limit increases to customers. The new business rules are described below. You may assume that the software has not been developed yet; the software will be implemented by a separate (from you) development group; and you will be responsible for independently testing the delivered software. Determine the number and types of test cases you would use to test this new capability, based on the following functional requirement. Justify your results.

The new program will read as input three data items for a customer and determine a new credit limit. The input items are the number of years as a customer, average monthly credit usage, and a credit score ( P = poor, G = good, E = excellent).
If a customer has a credit score of P no credit increase will be granted under any circumstances. Also, no credit increase will be granted to a customer who has been with WonderCard for five years or less and has a credit usage of $0 - $1,000 and a credit score of G.
A five percent increase will be given to customers who have been with WonderCard for more than five years if they have a G credit score and usage of $0 - $1,000; if they have been a customer for more than two years but not more than five years and have a credit score of G and usage greater than $1,000, or have been a customer for up to two years and have a credit score of E and usage not exceeding $1,000, or a credit score of G or E and usage greater than $1,000.
A ten percent increase will be given to customers who have been with WonderCard for more than five years and have a credit score of G and usage in excess of $1,000, or a credit score of E and usage not exceeding $1,000; or if they have been a customer for more than two years but not more than 5 years and have a credit score of E and usage in excess of $1,000.
A fifteen percent increase will be granted to only to those who have been customers for more than five years and have a credit score of E and a usage in excess of $1,000.
