8.1, 8.2, 8.3, & 8.5 all tie together. You could argue that 8.4 does as well. Heck, you could argue that all portions of 8 tie together.
I have often speculated that ISO 9001 got the order wrong, at least for how most companies function. I would have put 8.2 first.
In 8.2 you gather requirements, from the customer and other pertinent sources. This includes reviewing them to ensure they are complete, correct, and you have the ability to perform.
In 8.3 you take requirements, usually from what you did in 8.2 but from other sources as well, and develop a product. There can be a lot of liability in design so ISO 9001 has safeguards to help minimize the risk, including the keeping of thorough records and reviewing progress frequently. Inadequate records is a big source for nonconformances in design.
In 8.1 you plan for production. There is usually some overlap with 8.3. Many feel that 8.1 mainly deals with the development of the traveler (or whatever you call it in your organization, router, work order, job ticket, etc.). Often the traveler doubles as a quality plan. This production planning sets things up for 8.5 so that production takes place under controlled conditions. 8.1 also includes some big picture elements like do we have a big enough facility, do we have enough people, do we have enough of the right equipment, etc.
8.5 deals mainly with production taking place under controlled conditions.
I don't see how you can audit D&D without auditing 8.3, which was not on your original list.
I hope this helps.
