There are only two kinds of Business, either they wants to expand its user base or earn more money
It's up to designers to Designers to ask or in other words scrutinize more to get what exactly they are trying to do from where.
For example : In a social media company, A Business unit says wants to expand the user base to 5 Million this year , well thats a ambiguous statement to make .
Ask them what's their current user base like ?
What is the demographic split
What is the split of the base with respect to age
Where they are exactly weak it
What is the competition demographic split
Scrutinize more one single data and find out who you really want to target
Then building a solution would be right thing togo about
