  1. Group 3 Ballfinder a highly modifiable system

  2. Introduction • Quality attribute: Modifiability • Environment: • Random maze • Known number of balls • One light source

  3. Quality attribute scenario 1 The developer wishes to change or add modules to the system

  4. Quality attribute scenario 2 The user changes the maze. The robot should still be able to do its tasks

  5. Other scenarios • The user changes the number of balls. The robot incorporates the new value. • The user changes the drop-off-point (light intensity treshold). The robot is able to deliver the balls appropriately. • The user increases the robots speed; the robot starts moving faster and it is still able to handle its tasks without crashing. • The robot gets stuck, then gets unstuck.

  6. Logical view 1 Abstract AIController AIControllers Toolkit classes

  7. New AIController subclass

  8. Main controllers

  9. Complete logical view

  10. Process view

  11. FindBall algorithm

  12. DropBallCloseToLight algorithm

  13. What have we learned? • Architecture driven software development • The architecture design process was more time consuming than expected • Hard to share the workload among the architecture developers • The ATAM process can be a useful evaluation tool, although it might be more suited for larger projects.

  14. Achievements/Findings • A highly modifiable architecture • The controller works quite well, despite some minor quirks and the buggyness of the simulator • Poorly documented simulator; We discovered things about the simulator during implementation which we would have liked to have known during architecture design

  15. Conclusion • We have achieved our goals • The usefulness of software architecture design increases dramatically with experience • The architecture was helpful during implementation
