Minutes (no physical install) Several hours per month Rare Common (x 100?) Very variable - Time & distance - Some discounts Printed bill Internet a/c - Time, distance, roaming - Many discounts & packages Pre-paid Printed bill - Fixed recurring - Usage independent - Viewable on line By credit card
Delivery Promises To Financier: promised profit. To end customer:- service activation in promised time the contracted services at the contracted price robust and dependable.five 9 s? problems fixed in promised time billing accurately, understandably, responsive.
Make a Profit: It s easy! Profit = Income - Costs (and some tax!) Income 4No. of Customers *Revenue/Customer 4Interconnection charges & Transit Traffic Costs: 4Network: Equipment and build 4Support & Facilities: IT, Planning, Buildings 4Sales & Operations: People, Processes, Systems (BSS/OSS) 4Interconnection costs.
Operations Means Test An organisation should be able to positively answer four basic questions regarding any service it wishes to offer. Do we have the Means to Sell This Product or Service? Do we have the Means to Activate This product or Service? Do we have the Means to Bill for This Product or Service? Do we have the Means to Maintain This Product or Service?

Summary Theory and Reality are rather different! Things are set to become more complicated in: 4Types of Network Equipment and rate of change 4Less standardisation Increasing demand for: 4Instant response (activation, billing etc) 4Multiple services, single managed infrastructure 4Customer Self Care. Forward planning is everything Despite the technological wonders, the most common problems - and the most difficult to solve - are interfaces and finger troubles.
