New systems architecture and system plan
The customer provided a number of wholesale international telecommunication services in the businesses of capacity, data and voice. Recently it had redefined these services, prompting the Information Systems area to create a new functional architecture for the company's information systems. To this end:
- A process model for the telecommunications industry was identified to serve as reference (the eTOM model from the TMForum was chosen for this)
- A detailed analysis of the currently supported functionalty in the existing information systems was carried out, mapping these functionalities into the reference model
- New business requirements to be supported in the future information systems were identified
- A detailed analysis of the new services to provide to end customers was executed, together with the definition of the corresponding support processes and responsible roles, to derive additional new requirements for the future new systems
- A new information systems functional architecture was defined, aligned with the reference model and focused on supporting all the new requirements
- A functional architecture evolution plan was established to arrive at the newly defined architecture
In a second phase of the project a more detailed evolution initiatives analysis was performed, that allowed the creation of an Information Systems Strategic Plan that supported the transformation to the new model. Each of the evolution initiatives were analysed in terms of implementation alternatives, qualitative and quantitative comparison and description of projects (and their estimated duration) for the chosen alternative.
