Airlines, or for that reason any firm looking to venture out into a new market or business portfolio spend a hell lot of money hiring professional consultants/experts even top financial consulting companies, who do a complete market research and then provide the company with a report on the feasibility of the business plan and i am sure that an organization such as TATA-SIA must have hired the best in the business for their business plan evaluation. Then, The top executive management ( generally guys from top business schools) study the report, endless discussions and meetings take place and finally they conclude whether to go ahead or not!! Offcourse this doesn't guarantee success, but i was just wondering why couldn't they log onto pprune and get the expert opinion by our own pundits here...
