The problem statement of a project helps to identify:

A problem statement articulates the gap between the current state and the desired state by identifying the specific roadblocks or impediments that are preventing progress. It frames the core issue the project is chartered to solve, making roadblocks the central element of a well-written problem statement.

A connection to a larger program describes a program relationship, which is captured in the project charter or business case, not the problem statement.

Reason or purpose is captured in the project objectives or business case, not the problem statement itself.

Start and end dates are scheduling constraints documented in the project charter or schedule, not the problem statement.
