Analysis CRC Stories - short UCs on CRC (5’’ by 3’’) cards for all Use Cases … then play cards with the customer to decide which features will be implemented!

Testing Test first – Write the a unit test for the functionality you are developing before you write the component and maintain the test while you do development. Unit Test - Create and maintain a Unit Test for every major component of the system Application Regression Testing - base Regression Testing on Unit Tests. Any other way to do it will duplicate resources and knowledge requirements. Multi-application/system regression tests. 06/07/09 Ravindra EAP
