5. 5 T-76.4115 Iteration demo Status of the iteration’s goals  Goal 1: Implementing use cases  UC3.3 Display rooms available  UC3.4 Book rooms  UC3.4.1 Display hotel and room info  UC3.4.3 Input booking information  UC4 Search reservations  UC5 Cancel reservation  OK  Goal 2: Testing for good quality  OK  Goal 3: Improving process  OK  Goal 4: Using SEPA practices  OK  Goal 5: Making sure that requirements are fulfilled  OK

6. 6 T-76.4115 Iteration demo Customer goals Goal Achievement criteria StatusComments Ascertaining feasibility of iTV Analysis and rationale approved by Hotelzon See technical documentation Developing working version of hotel booking system for iTV Approval by Hotelzon in acceptance testing Main functionalities searching hotels, making reservations and cacelling reservations implemented Generating ideas on how to utilize iTV in future N/A No focus was put on this because of lack of time. See “development opportunities” for some input on this goal

11. 11 T-76.4115 Iteration demo Performed QA practices  Test-case based testing  Exploratory testing (peer review and acceptance testing)  Static review  Coding conventions  Prototyping  Heuristic evaluation  User interviews  Pair programming  Unsystematic unit testing by developers, e.g. JUnit used  Security testing (generating list of security issues)

12. 12 T-76.4115 Iteration demo Defects and other quality metrics  Major bug still open: Screens cut texts too short, especially hotel and room descriptions Bugs BlockersMajorMinorTotal Reported in I1 06612 Reported in I2 5201843 Reported total 5262455 Open 0167 Metrics Value Bug count 1+6 Security issues 1 (locking of inputs) Usability (time) ~5 minutes to make reservation Code documentation Code documented

13. 13 T-76.4115 Iteration demo Quality dashboard and goals Part of the system QualityConfidenceComments Search hotels HighSeems to work nicely Make reservations HighSome small bugs Cancel reservations HighSeems to work nicely Usability  High Most violated heuristics resolved, some negative comments about usability in user interviews and peer testing – have most to do with input and connection issues Security  Low1 issue identified through brainstorming Maintainability MediumCode properly documented. Legend Confidence: Low-Medium-High Quality: = quality is good  = quality seems ok  = quality is bad

14. 14 T-76.4115 Iteration demo Next Steps  Future of iTV is still uncertain  If application is to be used commercially, some tasks must still be done  Testing on real set-top-box  Fixing truncation of texts  We suggest that Web Service Interface should be further developed  Simplifying common queries  Fixing some mistakes in the interface documentation  Our parser classes can successfully be used in other applications also
