  3. This week • More system design examples • Building models • Abstract thinking • User interface design rules • Tutors • Visio narratives • RyanAir example MBS (MIMAS) / MIS533 / Deploying IT Resources

  4. More systems design examples • Quality Assurance database for cheese samples (volume) • Gathering customer order details into one system: late changes! • Survey questionnaire processing application: correlations • Payroll application, dealing with events (emergency tax, P30, …) • Supermarket point of sale system, activating new products (special offers) MBS (MIMAS) / MIS533 / Deploying IT Resources

  5. Bad systems design • SNCF : ticketing system • Bank of Ireland on-line (what direct debits are on my account?) • ERP systems: getting reports out • Your own examples? MBS (MIMAS) / MIS533 / Deploying IT Resources

  6. . . . The design of your software's interface, more than anything else, affects how a user interacts and therefore experiences your application. Tandy Trower, 1994 MBS (MIMAS) / MIS533 / Deploying IT Resources

  7. User Interface Design Rules • Rule 1 • Making the Interface Simple • Rule 2 • Allowing Users to Be in Control of the Software MBS (MIMAS) / MIS533 / Deploying IT Resources

  8. Rule 1 : Making it simple • Making the Interface Simple • KISS, Keep It Simple and Straightforward • Are all fields or choices in your applicationnecessary? • Making the Interface Transparent and Natural • Don’t clutter the interface • Labels, static text, check boxes, and option buttons • Can user look at screen and figure out what to do? MBS (MIMAS) / MIS533 / Deploying IT Resources

  9. Rule 1 : Making it simple MBS (MIMAS) / MIS533 / Deploying IT Resources

  10. Rule 2 : Users in control Some of the ways to put users in control are: • Making the interface forgiving • Making the interface visual • Providing immediate feedback • Avoiding “Modes” • A mode is something you must cancel before doing something else • Making the interface consistent MBS (MIMAS) / MIS533 / Deploying IT Resources

  11. Rule 2 : Users in control MBS (MIMAS) / MIS533 / Deploying IT Resources

  12. Your tutors Visio – Access • Run Zhang • Aoife Mac Sharry SQL - Oracle • Una Dunne • Brian Cummins MBS (MIMAS) / MIS533 / Deploying IT Resources

  13. Visio narratives • Grocery Store • ATM • Budget monitoring • RyanAir ticket purchase • Purchase request and payment • UCC travel requisition • Film festival MBS (MIMAS) / MIS533 / Deploying IT Resources

  14. Visio & database manuals • Katie Dineen • Room 3818 ORB • By end of week MBS (MIMAS) / MIS533 / Deploying IT Resources

  15. Building a model • Process Flow • Data Flow Diagram • Context diagram • Processes • Data Flow • Data store • External entities MBS (MIMAS) / MIS533 / Deploying IT Resources

  16. Example : www.RyanAir.com MBS (MIMAS) / MIS533 / Deploying IT Resources

  17. Example : www.RyanAir.com • Input : • Flight details (eg. SNN-BVA, 8 Oct, 10.35) • Credit card details (eg. VISA no, Expiry date) • Process : • Confirms price (eg. EUR 79) • Makes reservation & processes payment • Output : • Reservation reference (eg.CGHKCA) MBS (MIMAS) / MIS533 / Deploying IT Resources

  18. Process flow MBS (MIMAS) / MIS533 / Deploying IT Resources

  19. Context diagram Flight reservation Seat availability Flight Operations Passengers Payment On-line reservation system Reservations Reservation # € Accounts Seat prices Flight Schedule Timetable MBS (MIMAS) / MIS533 / Deploying IT Resources

  20. Purchase request and payment • Departments make spending requests • Budget is checked in the allocated budget file • If budget exceeded, request is rejected • Approved requests are stored and used to create Purhcase orders (PO’s) for suppliers • Goods received notes (GRN) are matched with PO’s to identify any discrepancies • When supplier invoice is received, 3 way match is made between PO, GRN and invoice prior to payment MBS (MIMAS) / MIS533 / Deploying IT Resources
