Do not throw away process because bad and wrong processes exist. Anytime you have a process you need to have a process in place to review and modify the process as needed. You should reward people for successfully changing the process - enough that people don't feel like it is a wasted effort, but not so much people look for ways to change it just to get the reward.

The right process is very valuable. However I will fully agree that there is a lot of bad process out there that people are following because change is too hard (sometimes this is all in their head and change is easy if you would just try!)
