5. Consequences to the iGT UNC of deploying the CSS design for switching
Possible areas that might require attention under existing governance:
Additional data fields and their population
Redefinition of current data fields
Changes to existing processes that will continue post CSS implementation
Data cleansing
Removal of retail elements from code (e.g. switching, objections) required for implementation of the CSS (i.e. removed and placed in RECv1.0 or v2.0 and not RECv3.0)
