There seems to be a misconception among several forum members that 'validation' is just some step. (Not specifically pointing at your post.)
(Disclaimer before any terminology corrections - we all come from different industries. I'm mostly regulated medical device. I'm using the terminology in my field. But whatever the terminology, the steps are the same. So asking we don't get stuck in a terminology discussion . )
Software validation is a subset of design verification - it is the first step of testing an engineering product. Requirements are established early on for the product - software validation means that those requirements have been tested to ensure the finished code does what it is supposed to do. While it is rare to be caught off-guard and have a test fail at this point (most engineers are running tests on their work prior to submitting for validation), it happens. Code from different engineers is interacting and the final software may fail a validation test. If that's the case, then the failure would be fixed and depending on how embedded in the code the specific module might be, one or more test cases will need to be rerun.
System validation is completed after software validation successfully passes. It's similar to software validation - but now the validated software is interacting with previously verified hardware - and new possibilities for failure exist. Again, if there is a failure, it will need to be fixed. And steps will be repeated.
Validation is not just a step, it's the testing designed to uncover failures before product is released. It's not unusual for a failure to be uncovered - and then it needs to be fixed. And then timeline is impacted. "Release expected in December pending validation" is perfectly reasonable in that context.
I'm not saying this is what happened here, but when I saw that statement before placing my order mid-December, I expected a much later release and would have been pleasantly surprised (and happy for the team) had it been released on that timeline. As it stands, I suspect they were all working over the holidays to fix whatever failed validation.
I spent yesterday driving on 17.11.10 and was impressed over some of the questionable circumstances it handled. Kudos to the team for the strides made in recent months. Can't wait for the next iteration
