3. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE Have you ever encountered problems using architecture in your project?
4. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE I would like to share the examples of my projects and their countermeasures.
5. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE ABOUT MOBILE ARCHITECTURE ▸ MVC ▸ MVVM ▸ Clean Architecture ▸ VIPER ▸ Flux ▸ Redux etc. Model View ViewModel Retrieved from https://ja.wikipedia.org/wiki/Model_View_ViewModel The Clean Architecture Retrieved from https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html
6. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE WHAT IS THE PURPOSE OF AN ARCHITECTURE? ▸ Easy to respond to specification changes. ▸ Increased productivity due to reusable design. ▸ Have common awareness within the team. ▸ Improved readability. ▸ Make test code easier to write.
7. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. ▸ There was a problem with the architecture in use. ▸ Difficult to set the role according to the architecture. ▸ There is no architecture. exception
8. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. View ViewModel Model API, DB Access etc..
9. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. View Model API, DB Access etc.. Anti pattern
10. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. Difficult to maintain View ViewModel Model
11. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. Generate the same source code Class function
12. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. Generate the same source code Class function Anti pattern copy
13. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. Degrade occurs when updating App Ver.1.0
14. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Development not fit for architecture. Degrade occurs when updating App Ver.1.0
15. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS App Ver.1.0 ▸ Development not fit for architecture. Degrade occurs when updating
16. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS App Ver.1.0 App Ver.1.1 ▸ Development not fit for architecture. Degrade occurs when updating
17. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS App Ver.1.0 App Ver.1.1 ▸ Development not fit for architecture. Degrade occurs when updating
18. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS Bidirectional access is possible Class function ▸ Development not fit for architecture. Anti pattern
19. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ Difficult to set the role according to the architecture. View ViewModel Model Class Which one? MVVM Example
20. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ There was a problem with the architecture in use. MVVM Example View ViewModel Model
21. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ There was a problem with the architecture in use. MVVM Example View ViewModel Model fat ViewModel
22. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE PROBLEMS ▸ There is no architecture. exception
23. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Development not fit for architecture. Insufficient understanding of architecture.
24. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Development not fit for architecture. Insufficient understanding of architecture. ɾCreate a document. and check PullRequest. ɾIf possible, check with CI. Class Diagram Sequence Diagram Tool ɾPlantUML ɾmermaid.js ɾdraw.io ɾCacoo etc
25. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Difficult to set the role according to the architecture. ▸ There was a problem with the architecture in use.
26. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Difficult to set the role according to the architecture. Change according to schedule Architecture extension ɾExample MVVM → MVVM + Mediator Reduce man-hours Architecture changes ɾExample MVVM → Clean Architecture For multi-platform support(iOS,tvOS,MacOS)
27. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Difficult to set the role according to the architecture. Change according to schedule Architecture extension Architecture changes ▸ There was a problem with the architecture in use. Difficult to set the role according to the architecture. A specific class became fat.
28. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Difficult to set the role according to the architecture. Change according to schedule Architecture extension Architecture changes ▸ There was a problem with the architecture in use. Difficult to set the role according to the architecture. A specific class became fat.
29. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE COUNTERMEASURE ▸ Difficult to set the role according to the architecture. Change according to schedule Architecture extension Architecture changes ▸ There was a problem with the architecture in use. Difficult to set the role according to the architecture. A specific class became fat. Should consider architecture. There is no architecture. exception
30. PROBLEMS AND COUNTERMEASURES IN EXECUTING MOBILE ARCHITECTURE OVERALL SUMMARY ▸ It is not essential to design the architecture. However, risk can be reduced by designing and matching implementation. ▸ If the architecture does not work well, there is a problem with the information sharing process.
