One of the pitfalls of applying process improvement is to stay using the same old process and having a parallel project that just produce the required documentation. Project documentation is actually important but it is just documentation.

To make things clear, here is an example. If you developed a design document early as opposed to documenting the design after the actual implementation. The process improvement approach will change the way you do your work and will direct you to think and plan using design document. You will make reviews and inspection on time per the defined process. The other approach lets you developer design in the same old way and before QA audit or before appraisal, you will create a design document.
