Description

This curriculum spans the technical, operational, and governance dimensions of deploying data mining in telecommunications, comparable in scope to a multi-phase advisory engagement that integrates analytics into core business processes such as network operations, customer management, and regulatory compliance.

Module 1: Defining Business Objectives and Scope for Telecom Data Mining Initiatives
