Telco Billing System Implementation Methodology
This post is describing the implementation methodology of the online software applications that cover the day-to-day business activities of the primary activities as described in Software Application Map.
The implementation methodology depends on the implementation mode.
The implementation mode depends on the status of the operator. If the operator is a new operator and does not have a billing system, then it is a green field implementation mode.
In case the operator already has an existing billing system then it is a migration implementation mode.
Regardless of the implementation mode, the primary activities and support activities business processes of the operator value chain must exist as prerequisite for the implementation.
Implementation phases
Billing system implementation consists of the following phases:
Dependency
The scoping phase must be finalized first before starting any other phase. Going live plan may describe the level of parallelism between the phases that follow the scope phase in light with the operator business.
Green Field Implementation
Green field implementation is used for new operator ,
The advantages of a green field operator are :
will be to the minimum as the operator will have an option to implement the business process that already exists in the software application
does not exist, and this will minimize the time of implementation.
The risks that exist in a green field operator are
is new for everybody including the operator team, where your analysis question may not have any answer as everybody lacks knowledge about the surrounding environment
Integration with network elements
as with everything in new there is a probability of having many problems in such integration, starting from unsupported protocol ending with not finalized communication specification
Roaming Agreements and clearing house connections
The above are the main risks where the going live plan must find a resolution for those risks
Migration Implementation
Migration implementation is used for existing operators that have an existing billing system.
The advantages of a migration implementation are :
All integration protocols and standards are in place
All Business processes are defined and in place
The operator team knows the surrounding environment very well and will have an answer to all your analysis questions
The risks that may exist in a migration implementation
The above are the main risks where the going live plan must find a resolution for those risks.
