  1. End User Applications What to build

  3. The Role of End User Applications Desktop tools / do-it-yourself queries Ad hoc power user End user applications Push-button knowledge worker Standard report customer Operational reporting environment

  4. Application Template • Provides the layout and structure of a report that is driven by parameters • Users set parameters from pick lists or drop down menus

  5. Cognos PowerPlay – web reports/slicing and dicing/data analysis, based on cubes.

  6. Template Design Steps • Identify an initial template set. 10 – 20 high value templates. • Collect report candidates. What are the important report requests? • Consolidate report categories. Based on data needs and type of report. • Prioritize the list.

  7. Common Report Types • How’s business? • What are the trends? • What’s unusual? • What is driving those exceptions? • What if …? • Make a business decision. • Implement the decision.

  8. Note • Do not recreate the past. • Old reports often do not reconcile • Recreating old reports gains little

  9. Template Management • Navigation. How do you find the one you want? • Shop standards. • Naming standards for templates and columns • Look and feel • Template creation • Definition and layout • Match with dimensional model • Review with users

  10. Application Development • Environments • Web based • Direct template access • Structured/menu based template access • Custom coded

  11. Data Requirements It is hard to evaluate forms and templates without meaningful data. Problems to manage include: • Meaningless descriptions • Duplicate dimensions or dimension access keys • Incorrect dimensional relationships • Data not matching legacy reports. May be a legacy problem.

  12. Managing the process • Remember the milestones • First demo 25% • System test with all modules 25% • Validated in simulated production 25% • Documented and delivered final system 25%

  13. Managing (cont.) • Code is not self-documenting • Use a bug reporting database or log • Acknowledge bug reports from users and testers • Place a high premium on testing and repairing
