SCE cGIS Consolidation: Network Data Acceptance Journey• Matured validation process and tools enabled data acceptance

• Business stakeholders were strongly engaged during the process

• Acceptance process was mostly automated

• Acceptance quality was benchmarked at 98%

• Numerous source data issues surface for further review(s)


Data Acceptance Parameter

AQL Examples of Quality Checks conducted Nature of checks

Network Connectivity (Geometrical)

100% 1. Physical connectivity in Circuits2. Logical connectivity in Structures3. Logical connectivity relationship

100% Automation checks

Data Model Compliance 100% 1. Relationship validation2. Mandatory field validation3. Business rules validations

100% automation checks

Feature Capture and placement, attributes capture, Cartography and Annotations

98% 1. Feature existence validation2. Feature placement rules validation3. Annotation placement rules validation4. White space validation5. Attributes capture rules and validation

Mix of automated, semi-automated and manual validations based on source type

Completeness check 100% 1. Validate feature capture for sampled locations Random sampling

cGIS Consolidation – Key Challenges

• Achieve business owner data buy-in

• Align two separate data systems (structural and electrical)

• Build a data system minimizing user change while protecting operational systems

• Enable IT (system) and business (data) alignment during development

• Assure ability to transition a current set of data upon final system cut-over


Change Management challenges and opportunities


Change Management Area

Challenges Methods toaddress challenges

Management • Lead the need for change• Align the business to achieve the optimal

results• Support adoption of new systems

Align solution to need

Business • Enhance organizational productivity • Gain confidence in the component additions

to the systems o New Landbase o Integration of previously isolated data

Sufficient time in review and testing; hear and address concerns

IT • Support new processes associated with data management

• Gain confidence in the external code development

Leverage current processes – both sides grow together

SCE cGIS – Enables GRID Modernization Investments

• Enabler for planning, grid operations, metering, distributed generation management, situational awareness, and outage management

• Key to data quality improvements – Transformer-Meter connectivity; Critical-to-Outage management operations

• Establishes the framework for single instance of truth to enabling structural and electric functionality into single applications

• Drive grid modernization technology through new network channels
