To examine the advantages and disadvantages of software outsourcing, as well as the application of lean principles to software development, Harvard Business School has done a case study on Wipro's innovative Factory Model approach. It specifically explores Wipro's experimental use of lean principles as a source of new competitive advantage in software services.

The case study addresses the advantages and disadvantages of software outsourcing and how to mitigate the effects of, for example, lock-in and hijacking. Explores how Wipro has helped its customers deal with these issues and looks at the changing competitive role of Indian outsourcers (from low-cost, to high-quality/rapid turnaround). Specifically explores Wipro's experimental use of lean principles as a source of new competitive advantage in software services. Also addresses the issue of standardization in information technology, examining why companies progressively develop so many standards and how companies like Wipro can help them standardize, thus limiting one of the primary drivers of companies' IT costs.

A copy of the case study can be retained from either Wipro or Harvard Business School.
