• Help to identify the demand for BroadBand Help to identify the demand for BroadBand applicationsapplications

• Allow to match operational requirements with Allow to match operational requirements with the system architecture, network the system architecture, network management and protocolsmanagement and protocols

• Crucial for the success of developing new Crucial for the success of developing new technologytechnology

• Essential to know what users require Essential to know what users require • Avoid developing non-useable technology Avoid developing non-useable technology • Involving users in early stage gives a more Involving users in early stage gives a more
