Find and eliminate defects early in the development life cycle in order to cut the defect-fix costs. Iteration planning starts each iteration. Starting with a simple design just enough to code the features at hand and redesigning when required. The unit tests are automated and eliminates defects early, thus reducing the costs. Programming in pairs (called pair programming), with two programmers at one screen, taking turns to use the keyboard. Working software over comprehensive documentation. This becomes expensive because of −. Testing starts only after coding is complete and testing is considered as a tester’s responsibility though the tester is not involved in development. In the 80s and 90s, Smalltalk Culture produced Refactoring, Continuous Integration, constant testing, and close customer involvement. Facilitates effective communication and continuous collaboration.
