An intensifying IT skills shortage, initially led to expanded use of alternate sourcing options like independent contractors, application service providers, external integrators and remote programming resources. This further led to increased dependency throwing open to many management challenges like challenges in project management framework and risk mitigation activities. This further evolved to an emerging method called as global delivery model. The global delivery model seeks to achieve an optimization of variables like cost, quality, time to market, etc.

This method has evolved further beyond a temporary answer to tighter budgets. There are definite tangible benefits seen in this model and currently, the industry is seeing this as a more appropriate model and are restructuring their entire operations to make the global delivery model as a standard model.
