Company A is a nation-wide leader in commercial demolition. Having just celebrated its 100th year of operations, the company decided to begin doing work internationally.

This will ensure transparency across the organization and enable better decision making.
The business analyst (BA) at Company A has recently completed several rounds of elicitation to determine the requirements for the new, web-based system. Over 1250 requirements were elicited.
