🎯 Overall Summary

Iteration 7 focused on metrics & observability, routing architecture, simulation features, and UI enhancements. This iteration delivered comprehensive metrics tracking for frontend actions and backend endpoints, Python application performance monitoring, vehicle inventory management, HQ widget implementation, and driver shift schedules. Key achievements include Grafana dashboard migration to a standalone package, OSRM decoupling via adapter pattern, MapController refactoring, unsaved changes protection, and resume simulation functionality.

🔄 Retrospective

What Went Well

  • Got most of R2 sim behaviour implemented
  • Usability test strategy is looking strong (+1)
  • Great simulator enhancements (routing engine adapter, decoupling, entity method refactoring, driver schedules)
  • Great pair programming for tasks (+1)
  • Improved logs & metrics to better understand the app
  • Good teamwork - people volunteer to help (+1)

What Went Wrong

  • Blocked waiting for heavy sim PRs (+1)
  • Left big PRs to last minute
  • Last minute request from Fares for usability tests
  • Bit off more than we can chew for work (flat burndown)

What Can Be Improved

  • Communication between team members when schedule or technical blocks arise (+1)
  • More communication with stakeholder (understandable for past weeks due to the break/holidays) (+2)
  • Work loads could have been better spread between team members according to task weight and everyone's schedule (+2)
  • Burndown chart a bit lackluster, 40-48% completion (+2)
  • Be willing to hold design reviews for giant / complex implementations
