Mike Pietrucha thinks that the USAF needs to return its development and procurement programs to the mid 1950s, when it developed the 5 frontline Century Series fighters.

1. Senior Staff (Major or higher) exempted from up or out.
2. No rotation out until full production procurement, defined as 25% of the original order, is complete. 
3. A prohibition on such staff working for defense contractors for 10 years after leaving the service. 

This would make decades long product development cycle a career killer, it would prevent program changes as management rotates in and out, and it would incentivize some alacrity, and time is (taxpayer) money.

Also, the perfect is the enemy of good enough:  It makes no sense to bankrupt ourselves in an attempt to completely overmatch any potential opponent.

We are spending more on defense than the next seven countries combined, and our roads are falling apart, our schools are underfunded, healthcare is unaffordable for much of the population, and life expectancy is falling in many regions.

We cannot afford our bloated military or our bloated weapons anymore.
