Describe the necessary conflict between marketing managers and finance managers. Why is it necessary?

There is necessary conflict between marketing managers and finance managers because they are constantly fighting the battle of where to spend money. Marketing departments want to use money to heavily advertise their company/product, brand themselves within the public eye, conduct research and more whereas finance managers focus soley on the budget and finances of a business. It's important for them to have conflict or each department could be overspending or underspending where necessary if they didn't hold each other accountable.
