Taking the example of the classic engagement model,  the offshore web development and software development team becomes a virtual extension of the onsite team since both share the same development environments which are remotely connected through a dedicated Virtual Private Network (VPN), put network or educated leased lines, leveraging out offshore development hi-tech infrastructure. Throughout the Software Development Life Cycle (SDLC) there is day-to-day interaction between on-site and offshore teams and check-in/out from the client development environment.
