In Marketing the truth is being changed to market demand for the better.
In Sales the truth is being adjusted to the requirements of the customer for the better.
In both departments reality is being enhanced.
Not lies but the reality is slightly changed in order to portray better.
The real truth could be too hard or harsh without leaving no room for any imagination.
In the end both marketing and sales are presenting the reality more positively for their own benefit. Maybe even for the benefit of the customer as he will believe he is buying a better or more suited product or solution.
Marketing and Sales never lie.
What do change or present slightly enhanced about your products or services to your potential customers?
