I appreciate the views of other gentlemen on Finance Vs Marketing.
In my view you can never solve this puzzle that "Whether Cock comes first or Egg comes first". Similarly you cannot generalise whether Finance is better or Marketing is better.
Like after coming from hardcore finance background I will always vouch for finance but there is one well proven fact that for any business Marketing is like a 'Visiting Card' I mean which gives the idea about the nature of business and which ultimately results in the foot-fall of customers for the products/services of the company.
On the other hand, apart from all this if the Financials of any project will not be to the mark, product can never take-off from prototype stage to final stage. So in short Finance works as the heart or lifeline for any project.
To summarise my views it is and it will still be a debate.
