Thanks Deepu, more examples is helpful.
I'm familiar with CMMI framework, software development and iterative development (eg, example given).
What I am wondering is if your existing QMS is too prescriptive (as Harry picked up) and /or too heavily based on a strict 'manufacturing physical product' model, and hence some of the problems you are having?
A decent QMS must enable the business to do its business, not strap it into a straitjacket. Your business ain't the same as a manufacturer.
When you mention 'tailoring' and creating an entirely new process (or perhaps a once-off process), your system must and should cater for that. And yes, it's entirely reasonable to have that in some kind of 'R&D' status for a while. Covering it in the Quality Plan is fine. Process change? Maybe, if it's changing an existing process.
Whichever, I'd be looking to specify the minimum inputs and outputs you must have though, in order to keep some kind of control over such, and ensure it doesn't become a backdoor kind of 'we don't have to follow our system'.
#1: IF your customer modifies their acceptance criteria, you can 'release' it. IF they don't, then you have not met their criteria. You might give them a demo version only (eg, for an expo), but you cannot release as 'final' because you have not yet fulfilled their stipulated requirements.
#2: I agree with the team. They aren't reworking, but iteratively developing. If your QMS is too rigid as to permit that, or requires a 'deviation/exemption', so be it. Though I'd want to make it more flexible, myself.
#3. Let common sense apply! Again, sounds as though your QMS is too rigid here. What is the result you're trying to achieve? If you can get the data on hours from customer's system, and your management is OK with it, fine. Otherwise, you're duplicate data entering, which seems pointless.
#4. Who is 'the QMS' which has banned inflammable stuff? Again, surely common sense should apply!! Regardless, whether such stuff is banned/not banned has nothing to do with any mandatory requirement of ISO 9001. Sounds almost as though someone is using 'ISO 9001' as a big stick rather than an intelligent and useful management system.
