Describe lenin's new economic policy (nep)?

The N.E.P. was masterfully designed to bring capital into the state, which it did, and to help it prosper economically. However, some socialists believe it may have gone too far with its free-market economic style and possibly could have lead the Soviet Union into permanently possessing a capitalist economy, which would have destroyed the socialist priority. The original plan, however, was to havecapitalism in place until the economy was strong enough to achieve socialism.

It is meant that like tapestry scientific theories often need to pull out since they are not relevant and often times the whole chain of theories may be pulled out.
