  • 11. •Started from an innovation process; •FirstVersion in RubyOnRails; •Market opportunity: •Existing tools were having a hard time to enter in Brazilian Market - Customers valued what we’ve done: •Market Picture: •~250 competitors world wide •a handful of them market leaders •200+ competing on price with little differentiation generally providing bad service; •Existing solutions were heavy, hard to use, expensive and more like a white elephant OK, but why did we decide to build OnTrack? Friday, 28 June, 13
  • 12. And we knew we could do better! THE COMMON BELIEF Friday, 28 June, 13
  • 13. STARTED WITH Strong leadership: Product Champion Technical Leader THE BEGINNING Friday, 28 June, 13
  • 14. From the very beginning we’ve heard and observed our usersand have applied LEANand UX techniques to validate our ideas in the most effective and inexpensive possible way. THE BEGINNING Friday, 28 June, 13
  • 15. 4 SIMPLE PREMISSES Simple Easy to Use Totally Effective Elegant THE COMMON SHAREDVISION Friday, 28 June, 13
  • 16. WE AIMED: To boost collaboration THE COMMON SHAREDVISION Friday, 28 June, 13
  • 17. WE AIMED: Non Intrusive communication THE COMMON SHAREDVISION Friday, 28 June, 13
  • 18. WE AIMED: unprecedented traceability THE COMMON SHAREDVISION Friday, 28 June, 13
  • 19. WE AIMED: Revolutionary Usability (keyboard shortcuts) (undo/redo capacity) (no cruds) THE COMMON SHAREDVISION Friday, 28 June, 13
  • 20. WE AIMED: Mind Map like Tree Editing to manage scope THE COMMON SHAREDVISION Friday, 28 June, 13
  • 21. WE AIMED: Rich Single Page Web App THE COMMON SHAREDVISION Friday, 28 June, 13
  • 22. WE AIMED: To require no more than 10 minutes to be learned THE COMMON SHAREDVISION Friday, 28 June, 13
  • 23. WE AIMED: To require no technical support THE COMMON SHAREDVISION Friday, 28 June, 13
  • 24. WE AIMED: To require absolutely no configuration (ready to go out of the box, you just use it) THE COMMON SHAREDVISION Friday, 28 June, 13
  • 25. WE AIMED: To be resilient to different business scenarios capable of being deployed onDemand and OnPremisse THE COMMON SHAREDVISION Friday, 28 June, 13
  • 26. WE AIMED: To design everything with the user in mind User-Centered Design THE COMMON SHAREDVISION Friday, 28 June, 13
  • 27. The next step was to find the right technology to build it. We decided by GWT THE TECHNOLOGY Friday, 28 June, 13
  • 28. To support all those premisses and goals we had to develop a robust architecture: Should be Fast, Reliable and Scalable Should not be dependent on Network/Server latency as we didn’t want to let the user waiting. THE ARCHITECTURE Friday, 28 June, 13
  • 29. In order not to let the user waiting, we needed the entire model in each client, keeping it sync while processing transactions THE ARCHITECTURE Friday, 28 June, 13
  • 30. The solution: A Thick smart client with an asynchronous distributed architecture. THE ARCHITECTURE Friday, 28 June, 13
  • 31. THE ARCHITECTURE Friday, 28 June, 13
  • 32. Syncing Services Syncing Services provided Mode Availability; We decided by the command pattern providing an abstraction for actions; Actions are maintained in stacks; Small cheap diffs for actions provided undo/redo, collaboration, easy conflict detection and treatment, accounting and traceability; The execution of actions are the only thing that can modify the model, providing model integrity; The code for syncing is the same for the client and the server, once again providing integrity; THE ARCHITECTURE Friday, 28 June, 13
  • 33. Actions are all stored with version control, enabling the recovery of the state of the model at any given point in time providing unprecedented traceability; Any new implementation will take advantage of all past data; Snapshots are used as cache to reduce processing when load a state (all lazy loading); The client UI is updated as fast as possible so the user does not need to be waiting for AJAX callbacks; Server validations assure model consistency and together with conflict management and server push capabilities can provide a secure and reliable platform for intense collaboration; BENEFITS OF THE ARCHITECTURE Friday, 28 June, 13

  • 41. We truly believe, specially based on the feedback we’ve got, that we've developed the best solution for the niche we've aimed and the team is proud of its creation; We've learned that to build a good user experience, several factors have to be aligned; You have to go very deep in several disciplines; You have to use what you build; Once again, the essence of the Lean Pyramid and User Experience principles helped us to balance our efforts in all these disciplines; WE HAVE LEARNED Friday, 28 June, 13
