Outsourcing critical functions
This comment isn't about India; what follows could apply to outsourcing within the same nation. Nobody loves your business and your customers more than your employees. Nobody will be more willing to go the extra mile, including taking personal risks, than your own employees. Partly from loyalty, partly for fear of being fired, partly because of pride in their job. If you outsource a mission-critical function to another company you are at risk when the fertilizer hits the ventilation system and the provider has to decide who is more important.
