Mobile Devices Case/ p 71What are some of the benefits that organizations could realize by connecting all of their employees by mobile devices? • Provide “time” and “place” flexibility • Mobile sale forces could do product demonstrations, check inventory and place orders online real time while at the customer location. • Reduction of the time needed to locate other employees, especially when they are off-site. • Keep employees abreast of any important news when away on travel (conferences, meetings, presentations). • Increased available productive time, as constant connectivity allows for activities to be performed anytime anyplace.
Are the CIOs in the case saying that ROI is not important when deploying mobile computing devices? the estimated benefits obtained by the adoption of these communication devices are large enough that outweigh cost considerations and thus displace formal ROI analyses and concerns. This is what many have called “value” analysis which compares values to benefits as opposed to “cost” to benefits.
Blackberry popularity? • Single and integrated device for voice and data communications • Push technology – data is routed to the user rather than retrieved by the user • Operates in several different networks and countries • It is possible to view email attachments • Design features: high-resolution color display, long battery life, improved keyboard, etc. • Integrated connectivity applications (SMS, browser, organizer)
Learning Objectives • Describe several important trends occurring in computer software. • Give examples of major types of application and system software. • Explain the purpose of several popular software packages for end user productivity and collaborative computing. • Define and describe the functions of an operating system. • Describe the main uses of computer programming software, tools, and languages
Software A single program or a collection of programs which performs many task and/or system related functions Two types of software: • Application • System
Application Software • Personal Information Manager • Groupware • Organizational • Inter-organizational
Personal Information Manager and Groupware • Personal Information Manager (PIM) • Software for end user productivity and collaboration • Store information about clients, schedules, manage appointments, manage tasks • E.g., Lotus Organizer, Microsoft Outlook • Groupware • Software that helps workgroups collaborate on group assignments • E-mail, discussion groups, databases, videoconferencing • E.g., Lotus Notes, Novell GroupWise, Microsoft Exchange
Organizational & Inter-organizational Organizational They assist typical organazational tasks • Payroll, TPS • ERP,CRM • Web-based management systems Inter-organizational They provide links or cooperation between organizations • B2B system • EDI, SCM

Mini Case 1: Delta, Lufthansa etc.. Computer system technologies and functions that are included with self-service kiosks are • Networked special purpose microcomputer terminals, which include video touch screens as the user interface, along with a built in • High speed thermal printer for flight itineraries and boarding passes. • A magnetic stripe card reader that is used to read customers airline and credit cards. • Connected to credit companies and bank’s databases • Integrated with airline’s internal application system
Delta, Northwest cont • Possible other technologies • Connect with federal databases for customer identification • Speech recognition devices • Pen-based handwriting recognition features • Wireless links for travels with PDAs and Internet-enabled cellular and PCS phones. • Image recognition. • Identification recognition (fingerprints etc.)
The customer value of self service kiosks for airline check-ins is: • Customer More Control • Upgrades • Seat selection • Change flights/seat • Check baggage • Stand by • Less people interaction – for the introverted/misanthropic the reduction in face-to-face interaction can sometimes be beneficial • Time savings • Convenience • Family check-ins • Pay by credit card any upgrade/change etc.
Possible other services • Gate readers to update itineraries and boarding passes for connecting passengers whose second flight was changed or cancelled due to weather or other delays. • International documentation, facilitation and fee collection. • Thump print recognition • Cancel reservations and be credited or debited automatically • For international flights provide foreign ATM connections • Provide initial or supplement security screening using retina scans and marking boarding cards • Provide “alerts” on customer’s mobile for flight boarding (especially if they are missing or sleeping) • Connect to hotels to allow hotel check ins • Connect to car rental agencies for car rental agreementsMore specialized kiosks to allow travelers opportunity to handle future travel plans, adjustments as schedules change and other accommodations upon arrival at a destination. • Automatic update mileage etc.
The business value of self service kiosks in the airline industry is the fact that • Importance of JAD (joint application Development), how technical and business team can work together and complement each other and arrive at “solutions” • A win-win situation for both customers and businesses • Creation of a whole “new” platform on which to provide additional products/services that can provide strategic advantages • Help the bottom line • Economy of scales---Strategic partnership with other airlines for check-ins just like ORBITZ, TRAVELOCITY etc • Enhance customer goodwill (satisfied customer)
Still a strategic advantage? Maybe, not any more • Kiosk were competitive advantages when they started probably around 2002. Airlines offered miles to customers to use kiosk but now they are a necessity. • Many airlines still can not afford it However, Continuous improvements can still provide competitive advantage • Continuous improvement and streamlining of traveler check-in activities, especially after Sept. 11, will always be provide advantage. • A reduction of costs or a reduction in the increase in costs in a highly competitive industry will always provide advantage. • Continuous enhancement of customer goodwill will always be strategic: • Online entertainment (casino, massage, card games etc..) may provide some advantage, especially on international flights • Alter customer arrival to their home/business
