Vinay Tiwari finished his PhD research successfully by defending his PhD thesis on "Transition Process and Performance in IT Outsourcing".
He proposes two important suggestions.
1. The transition process in IT ousourcing will necessarily proceed in three sequential and conjunctive phases: transfer, adapt, and routinize.
2. One can shorten transition duration by chosing routines-based transfer mechanisms (like observation) and codification practices (i.e. using templates and interactive document reviews).
This dissertation is one of the first in the world that is using laboratory experiments in the context of IT outsourcing.
