What is Problem Statement

A problem statement is a script that answer these questions: what, how, where, when, why, and who.

The first step is to write down the problem at current state and expand on them by asking the following questions:

who is/isn't affected.
what is/isn't affected.
how does/doesn't it affected.
when is/isn't the problem.
where is/isn't the problem.

The Second step derives desirable outcome.

Problem statement is usually short and focuses on only one problem. It does not suggest a solution.
