IntroductionThe opportunity exists to enable visitors to locate points

of interest in metropolitan areas.

Our vision is to create a system that will allow users theability to locate restaurants, stores, parks,and other interesting places.

The primary customer(s) of the mobile concierge system would

inputs• Locate said points of interest• Provide expert reviews• Make reservations for hotels and

restaurants• Purchase tickets for theaters, movies,

sports events, etc.

Needs Analysis:Research

Maps• TomTom personal navigation• Garmin• Mapquest

Travel Guides• Frommer’s• AAA• Zagat Survey

Competition• Mobile Food Guide• American Express Centurion Service• Google Search• Mio DigiWalker H610• CitySearch

Stakeholder Requirements• Visitors

– Provide a response in less than 10 seconds– Must be a mobile and compact service– Provide directions to the location– Allow users to make reservations

• Manufacturers– Use standardized components (interchangeability)– Utilize tested and previously implemented technology

• Maintenance– Self Diagnostic– 99.9% availability.

• Regulatory Bodies– Conform to all regulations at each level of

government. • Mobile Service Provider

– The system must conform to TIA/EIA networking, 802.11x, standards

Acceptance Criteria

Customers will be able to• Locate restaurants, theaters, stores,

parks, and other interesting places. • Purchase or make reservations for said

services.• Have 99% coverage in major U.S.

metropolitan areas.
