Remove every profit barrier
- Find out the reason why ZRCC makes high profit (chapter 2)

In terms of crude oil cost examination, the planning department in charge of purchasing crude oil is linked with the production department in charge of processing crude oil. Both departments fully coordinate in controlling the purchasing time and crude inventory. The crude cost of ZRCC in 2013 is 72.82 Yuan/ton lower than the average cost of Sinopec.

ZRCC removed the profit barriers by establishing a three-level managerial system to make the management persons responsible for profit and unit operators responsible for production.
