Answer 1

Without cases we cant' do any work in any company.

Answer 2

A use case is a tool for defining the required user interaction. If you are trying to create a new application or make changes to an existing application, several discussions are made. One of the critical discussion you have to make is how you will represent the requirement for the software solution. 

Business experts and developers must have a mutual understanding about the requirement, as it’s very difficult to attain. Any standard method for structuring the communication between them will really be a boon. It will, in turn, reduce the miscommunications and here is the place where Use case comes into the picture.
