Software and hardware systems often affect far more than the department they are being installed in. They affect networks, staffing, schedules and many other routine aspects of the work environment.

As the scale of the project increases, so does the complexity.

• What does the client need to do?
  
• When do infrastructure changes need to be made?
  
• Who needs to be trained on what procedures?
  
• Where will equipment be installed, who will control access, and how will it be maintained?

It's best to answer these questions - and dozens of others that affect the success of the project - before the first box arrives at the customer site.
