Re: Looks like the technology hasn't been properly studied
So business start with an idea. Marketing helps them sell that idea. Business does well.
So, everyone gets more money. Marketing falls into the demographic and demand issue, seeing other similar models working, so say 'You need to design it like this so we can take a part of this demographic who want to buy it because see: Evidence' (Just look at laptop design in the last 15 years. Thanks apple. )
So business tells talented Engineers to do it this way. Engineers grumble because they are see the limitations of what is wanted and have to make nonsensical tradeoffs to provide what the busines are saying what people want.
Meanwhile, lots of people are decrying the new products as missing X and Y and why can't we have a longer batter life and they are ignored because no one is buying those things because see: Evidence from marketing. Only the .5mm thick battery ones are selling.
And we all cry: BECAUSE NO FUCKER IS MAKING THEM!
So...if you are a Product Owner, get evidence from everyone EXCEPT marketing.
