M Problem Statement: Accurately capture all the Metering Points M M M present in the network and place them in a Establish Hierarchy logical hierarchical tree. Solution: For each Meter present in the DB, use back- tracing to find its Parent Meter (Non- Consumer).

Problem Statement: D IT AU In the Existing levels of Hierarchy the “Inspection Area” (Area of Focus) is too big. Micro-Manage This is resulting in higher rates of “Resolution Audit Time” Solution: Introduce more layers (i.e. Meters) into the Hierarchical Tree in order increase the number of “Audit Sections” thereby reducing the Area of Focus.

Problem Statement: Update the Hierarchical Tree in case of any Network Changes such as Network Extensions, Capture Network Network Switching, etc. Updates Solution: Since all changes made to the network are routed via Business Process, update the Process Flow to trigger Energy Audit extract whenever Network Changes are captured.
