It’s a fulfilling job but I would say try to get out of the field ASAP and move into a more management role. Note that it is less stressful but at least you have a greater ability to change things
I would also be careful, some companies define observations more closely to opportunities for improvement, in that they are not necessarily a deviation but very close to one
Why would applicability remain for different cities and not for different countries? I guess for different countries it makes sense not to be applicable as the legal register/laws/regulations is different
