The point I have tried to make for quite a while is that you earn credibility here, it is not awarded because of who you are
Obviously GB you are in an impossible situation because the marketing dept and the design team are working together to cover each others tracks....they make claims you cannot back up...and you cannot simply say marketing, like many depts in this industry, are making up figures that no engineer would put his own credibility on the line for.
So you are stuck in the middle, knowing a lot, perhaps more than most here, but you cant truly demonstrate it because doing so would contradict the marketing from your own company. i have no idea what type of NDAs exist in England, but Im confident its clear you cannot contradict your own dept directly.
this results in your credibility being compromised. that is why i said from the beginning you are hurting yourself and your company if you are GB....not posting is better imo.
this could be seen as really insulting, or, perhaps as uncomfortably close to the truth. i would like you to participate in the discussion, but what has been infuriating for most is the slow drip of information and the quiet campaign to appear reasonable...but at the same time not just take a deep dive into the driver and truly explain the successesand failures of the design.
i get it...you cant. but also understand then why your words arent valued the way you would like them to be. assuming you are GB, you are "the man" at Tympany. but that business reality also causes you not to be seen as such here...you have to defend the company by your role even if the product has flaws, and that role prevents a real discussion imo.
