  2. Requirements for decision making and planning Content • Requirements to the Network Planner • Scope and activities within the network planning area • Strategic Planning and new Technologies. • Solution mapping per scenario ITU/BDT Requirements and Role of Network Planning - O.G.S.

  3. Requirements for decision making and planning Key requirements in competition • Business Oriented Needs • What are the best customer segments to address ? • Which services have to be introduced through time ? • What is the best service bundling per customer type ? • How to maximize revenues ? • How to reduce capital expenditure ? • How to reduce operational expenditure ?
