5. Watchdog Presentation

6. T-76.115 Project Review 6 Watchdog  Problem  Surveillance views had to be gone through manually to check the camera statuses.  Solution: Watchdog  Monitors status of network camera on predefined intervals  Latest ASAN configuration is downloaded from ASAN’s databese  A snap-shot of all the camera images fetched via HTTP  If an image can be retrieved it is analyzed for error situations:  Blackness: error if camera image is black during day time  No video: error if analog camera is not connected to video server  Status of the currently active malfunctions is kept up to date  New malfunctions are sent to the operator via email.  The status data is recorded and too old data is erased.  All system parameters are editable via web interface  The system has been built to accommodate easy adding of new camera models  Developed with Java 1.4.2 and MySQL 3.26  Running on Linux server

7. T-76.115 Project Review 7 Demonstration  Watchdog  Configuring ASAN database  This configuration can be changed on the fly  Global configuration options  Interval lengths, email addresses, sleeping period, and other settings  Main View  Status of each camera and an overview of the errors in past  A new check can be forced manually  Camera info view  Detailed history of a camera and its latest image  Some statistics about the errors in the history.  Malfunctions view  List of all malfunctions that have occurred  Technical data in this demo has been censored to protect customer IP

8. HourLogger Presentation

9. T-76.115 Project Review 9 HourLogger  Problem  Beconnected engineers have to check the statuses of the systems in the customer permises  These actions are currently logged to Excel sheets causing a hassle with the files.  Solution: HourLogger  A web based tool for logging and reporting technician's maintenance and support work hours per customer, per target and per work type  Produces monthly reports of the recorded work tasks in Excel format  Developed with Java 1.4.2 and MySQL 3.26  Running on Linux server

11. Project Evaluation

12. T-76.115 Project Review 12 Realization of Customer Goals  Goal 1: Create business value by reducing costs in Beconnected's maintenance / support work for its customers  Achieved!  Goal 2: The software should be ready for production use during the project  Failed – customer acceptance testing still not performed  Goal 3: The software should fulfill the minimum requirements and avoid unnecessary complexity  Mostly achieved. LogAnalyzer did not finish.  Goal 4: The software should be usable, reliable and maintainable  Achieved/not sure.  Goal 6: Execute project with minimum costs  Achieved: only 3250 Euro total and less than 3 hours per week on average  Goal 7: Minimum critical information leakage  Achieved: The project team was careful with this.  Goal 8: Get contacts to TKK students  Achieved: Team members were good.

13. T-76.115 Project Review 13 Realization of Project Team Goals  Goal 1: Return all deliverables on time  Achieved!  Goal 2: Get good grade  Dunno yet.  Goal 3: Produce useful software  Achieved.  Goal 4: High customer satisfaction  Achieved.  Goal 5: Learn more about software projects  Achieved.  Goal 6: Have a working team  Could have worked better…  Goal 7: Keep the work in the defined resources  Mostly achieved.  Goal 8: Learn to use new tools  Achieved.  Goal 9: To have fun  Achieved. Maybe it wasn’t as easy as expected, but challenging is fun too.

14. Software Metrics

15. T-76.115 Project Review 15 Realization of the working hours

16. T-76.115 Project Review 16 Realization of budget  Monthly allowance of € 100 for miscellaneous well justified project costs  Final costs in the allowance were from:  NDA mailing  Java books  Pizza and coke for group working sessions  Total costs were around 250 Euro

20. Working practices and tools

21. T-76.115 Project Review 21 Used work practices  Document vs. communication driven development  Iterative development  Chief engineer centered development  Roles and responsibilities assignment  Customer on-duty session  Risk management  Group working sessions  NDA and information publishing process  Documentation in English and in HTML

22. T-76.115 Project Review 22 SEPAs  Meetings Practices  Success  Pair Programming  Total disaster  Usability Tests  Lightweight but useful  Design Patterns  Didn’t apply that much for this project

23. T-76.115 Project Review 23 Used tools  Development Server  Severe problems due to low performance and no debugging facilities  CVS at HUT CC  Worked well  Eclipe IDE  Handy. CVS cliend could be better  Trapoli  Sucks! Poor usability!  Tiki and Bugzilla  Worked well

24. Problem Analysis

25. T-76.115 Project Review 25 Risks and Problems Summary  One group member had to leave abroad for a month in I1  Customer was often too busy to answer questions and provide feedback  Development server had very low performance  No separate testing environment  Quality problems occurred often in the deliverables of team members  Problems with used tools: usability problems, corrupting data, forgetting CVS commits, etc.  Compatibility problems between member goals, working habits, preferences, schedules occurred often, which slowed down development.  Customer could not provide a good development server on time  Customer did not start acceptance testing on time

26. T-76.115 Project Review 26 Changes to the project along the way  Small changes to requirements  Natural process of refining customer needs and finding out new requirements  I1 iteration was turned into prototyping and architecture implementation  Customer testing period had to be moved from I2 to FD due to busy customer schedule  Watchdog and Hourlogger features kept surprisingly well considering the difficulties in the project  LogAnalyzer was not finished  This decision was made very late in the project
