Thanks! I will take it as a add-on to my knowledge.
Here I am mostly talking about marketing.
Since, marketing is more subjective, experts marketers tend to use a strategy that is more convincing to the public based on neuroscience than telling the reality of the product, if the subjective views and the product to be market donāt align. 
Summary
Thatās one of the reasons in startups, the accounting department along with the design/production department always have conflicting views with the marketing department.
At the accounting and design/production department, they believe in the hardcore - what really the product is? who it is for? and who it is not for?
But the marketing department on the other hand say No. The features of the product doesnāt matter. What matter is what the customer think the product is intended for.
The key takeaway here is the word "think" which might not be real
Example: Customers are complaining that the public train is very slow. How can we solve that?
Accounting and Design/production Department: āWell, we are going to invest more money in research that which the design/production department will try to come out with a better engine that will make the train go fasterā
Marketing Department: āNo! We should rather employ attractive males/females with good communication skill, they will take care of customers request.ā
Surprisingly, the later is what the company will execute. Why? - 1) Time is not real. 2) It will be cheaper to employ those attractive personalities than to invent a better engine. 3) S*x appeals have high selling rate. 4) Increase PR.
Sad but truth
