2. 2 KEY KNOWLEDGE OF THE DOMAIN1. Electronic menu (e-menu) for restaurants2. Restaurant service process3. Software usability and Human-Computer Interaction (HCI)4. Software development methodologies and prototyping technique5. Mobile application development for e-menu on iOS or Android devices 3. 1) E-menu for Restaurants3 4. 4 1) E-MENU FOR RESTAURANTMain Objectives of e-menu (Jenie 2011) Display list of food and beverages including images Process the restaurant services from ordering to paymentThree general kinds of touch screen e-menu system (Conceptic nodate) Table side touch screen e-menu E-menu for waiting area Tablet e-menu Pictures are taken from Emenu USA (2011) and Conceptic (no date) 5. 51) E-MENU FOR RESTAURANT1 Table-side touch screen e-menuTable-side touch screen e-menu Equipment:Personal computer Installation: Need to modify tableBenefits No falling problemDisadvantages Difficult to install Difficult to install & Need to prepare electrical plugs at all tablesNeed electrical plugs Pictures are taken from Emenu USA (2011) and Conceptic (no date) 6. 61) E-MENU FOR RESTAURANT2E-menu for waiting area E-menu for waiting area Equipment: LCD TV with touch screen Installation: Need to prepare area to install Benefits Bigger images Less cost because it requires only one touch screenLCD TV Disadvantages Only one person can order at a time.Cannot order Not suitable for this case study restaurant becausecustomers can not order on their tables.at dining table Need extra space to install. Pictures are taken from Emenu USA (2011) and Conceptic (no date) 7. 7 1) E-MENU FOR RESTAURANT3Tablet e-menuTablet E-menu Equipment: Tablet e.g. iPad Installation:Dont need to modify tableBenefits Slim and small size Easy to install Build-in wireless connectionDisadvantages Small & Falling problem Smaller screen size than othersEasy to use Theft 8. 8 1) E-MENU FOR RESTAURANTAfter discussion with the restaurant manager and staff, we found that the tablet e-menu was the mostsuitable because it was smaller and simpler to install.

Final decision with restaurant manager: Tablet e-menu 9. 2) RESTAURANT SERVICE PROCESS 9 10. 102) RESTAURANT SERVICE PROCESSAnalysis of a existing restaurant service processIssues of existing system1. Need to wait for waiting staff before giving order and making payment.2. Waiting staff must deliver order to kitchen and bar.E-menu system1. Order is send directly from a table to bar and kitchen. Process of taking order & making payment can be improve by e-menu. Pictures are adopted from Crowston, Rubleske and Howison (2006) 11. 11 2) RESTAURANT SERVICE PROCESSProblem: Personal contact between waiting staff and customers DescriptionService Request Diagram E-menu may reduce the personalcontact between customers andwaiting staff (Studentwebstaff 2009). Solution The system should have a service request feature to call waiting staff. Request Waiter Request Main BenefitsCourse Customers can request services Request Billeasier compared to the existingsystem. Customers dont want to look aroundto find a waiter.Solution: Customers can request a waiter from e-menu system.Benefits: Customers can easily request a waiter.Pictures are adopted from Crowston, Rubleske and Howison (2006) 12. 122 ) R E S TA U R A N T S E RV I C E P R O C E S S As-it or current system1. Ordering Issues 2 A waiter must spend time to ServiceRequesttake and transfer an order tothe kitchen and bar. Customers are less inclined to1order more food during busyOrderingtime. Paper-based menus haveinsufficient information e.g.pictures and details of food.2. Request Service Issues A waiter has to observecustomers when they want torequest a main course. The customers have to lookaround to request waiter andThese issues can be solved by e-menu systembill. 13. 132 ) R E S TA U R A N T S E RV I C E P R O C E S S New Service Process by e-menu system1. Ordering2- Order is transferred to bar andService Requestkitchen automatically.- Customers find it easy to ordermore food and beverages.- Customers can check their1order status.Ordering- Customers can select menuwith full details and pictures.2. Service request- Customers can request serviceon e-menu- Waiters have more time toprovide service.E-menu can enhance ordering and requesting services 14. 3) SOFTWARE USABILITY & HCI HCI: Human-Computer Interaction14 15. 15SOFTWARE USABILITY & HCI HCI: Human-Computer InteractionImproving Software Quality by HCI design Quality of software should support Users can use software without specialised business needs.IT knowledge HCI is an important factor to measure Easy to use & without long instruction a quality of software (Gulati and (Edexcel 2010)Dubey 2012 , Majid 2011) Touch screen interfaces can enhance usability because it is easy to use. Developing e-menu system should concern HCI design. 16. 16 SOFTWARE USABILITY & HCI How to measure HCI Design?Good HCI Design & Example of applyingNo DescriptionUsability the concept for e-menu1Visibility Know result of each operation Screen is updated after placing order Customers can always return to a previous2 FeedbackEasy to return to a previous screenscreen of e-menu.Easy to recognize when use software Make user-friendly and non-complex user3Memorabilityagaininterfaces4Learnability Easy to accomplish basic tasks Reduce unnecesaary steps as much as possible5 EfficiencyQuick to learn and perform tasks Make it be simple and easy to use6Satisfaction Pleasant to use softwarePut nice images and suitable colours (Norman and Nielsen 2011; Nielsen 1993) Above criteria should always be concerned when developing an e-menu application.However, only usability is insufficient. Developers must be aware of SW developmentmethodology. 17. 4) SOFTWARE DEVELOPMENTMETHODOLOGIES AND PROTOTYINGTECHNIQUE 17 18. 4 ) S O F T WAR E D E V E L O P M E N T 18METHODOLOGIESAN D P R O TO T Y P I N G T E C H N I Q U EComparison table among Waterfall, Agile and RAD with prototyping approachRAD withNo Compared ItemWaterfallAgileDescription Prototyping Waterfall approach clearly separates development1Traditional approach Yes No Noprocesses, and doesnt return to a previous stage.
