A second source said that EOI states that all key managerial positions including but not limited to CEO, CFO, COO and the entire Board of Directors shall be held by individuals who are resident Indian citizens. This means, the source added, that no private company can actually hire a foreign talent at the top to spearhead the venture.
The sources also pointed out that annual turn-over of the single/lead company shall have minimum Rs 2,000 crore in the last three financial years (FYs). Also, the non-lead partner should have a minimum annual turnover of Rs 200 crore for the last three FYs.
The only company which fits this criteria is HAL, they said.

I would say that the current Tejas programmes are in the state they are in partly because of less than dynamic leadership from the government down. Excluding talent is not a good idea. Carrying on with the same company that performed so badly with Tejas is not a good idea. The brief seems to be written to ensure that the people institutionalised to accept failure with no sanction will be the people who will be running the show.
