Things to Consider• Evaluate what type of system works best in for YOUR
Utility• What is the total real cost? Up-front and long-term• Review a long-range plan with various departments
(Distribution, Customer Service, IT)• Determine if you want to use the existing assets (meters
& existing mobile RF) or replace everything• Compare the system offerings & weigh Pros and Cons• Communicate with other Utilities who have systems
installed• Determine if you have personnel to evaluate the
additional data
