Hi Jeniffer, Education, Transport, Education, Software, BPO etc are included in the links above. Please review them.

Hi Venkatesh, There are a few reasons why it has not succeeded as much as it should have. Small farmlands make it hard to reduce risks. The government initiative is limited. People who own agri-fields have limited education to understand and absorb such concepts. Any Agri-University in India has not tried to scale it up. It is not as if results are not available to India. Companies like Syngenta and Monsanto have been partnering with Agriculturists to reap the benefits in a partnering fashion.

Hi Sathiyaraj, That is a good explanation!

Hi Devang, Many companies including some of the e-commerce leaders that we work with have such Supplier Management functions. We conduct a full-fledged program on Vendor Managed Operations for such functions. This program covers efficiency in four sections. The outline can be seen here - https://www.benchmarksixsigma.com/corporate-programs/vendor-managed-operations-efficiency/. There is a large scope for cutting waste in each area. Hope this helps.
