    • WHITE PAPERRightsourcing –The Art of OutsourcingTesting resources are usually expensive, often behindschedule, and generally scrambling to understand the currentand next technologies and business domains. The effectiveuse of outsourcing will result in the establishment of a testteam that can handle these challenges.Software testing is becoming an increasingly critical component of the development life cycleand, as such, demands focus and experience. As important as testing is, companies should befocused on testing in the most efficient, cost effective way. A blended choice of offshore,onshore, and onsite testing resources can help to minimize risks, while maintaining high levelsof effectiveness, efficiency, and cost savings.

Effective outsourcing enables sustainable and efficient software testing under dynamic conditions, project after project. Testing is enabled by domain specific knowledge, by tools for test design, execution, and management, and by test methodologies and processes that verify and validate a range of work products of software application project teams. The testing processes are included within a Software Development Life Cycle (SDLC) and are constrained by costs, schedule, technology, and people resources. Testing resources are

Discussions with SDT clients and published articles indicate that there are serious issues with an outsourcing model based strictly on offshore testing when there is not sufficient support on- site.
