Most client/server applications are developed using a Rapid Application Development (RAD) methodology. Testers must "try to keep up" with these short development cycles. Earlier, non-client/server applications often took 18 - 24 months for full development and initial deployment. Now, with RAD, applications are delivered in multiple deployments or "chunks." Each chunk is based on the previous one and includes enhancements, modification, and fixes. Each chunk requires multiple builds or iterative prototypes. Each chunk requires testing, and all within the shorter, 3 - 6 month time frames!
