What if the process documentation isn't confusing and stupid because the author is bad at explaining things - what if the process documentation is stupid because the process is stupid and needs to be changed.
Another approach to this kind of thing is to reverse the sequence of "do it", "document it" steps and draft a rough version of the documentation up-front as part of an initial design, while it is cheaper to change the process or system, before work is done to implement it and roll it out.
