    Senior Application Developer for FBM e-Services
  • 2. It’s not that they don’t teach it
  • 3. Maintainability
    A measure of how easy it is to understand, modify, and extend your code
  • 4. Maintenance?
  • 5. Facts you only find out at work
    Writing new code is the first thing you do at school, but the LAST thing you do at work
  • 6. Facts you only find out at work
    You WILL spend most of your time trying to understand the code some other person wrote
  • 7. Facts you only find out at work
    “Maintenance typically consumes 40 to 80 percent of software costs” – Robert L. Glass
  • 8. Testability
    The degree to which a system or component facilitates the establishment of test criteria and the performance of tests to find whether those criteria have been met
  • 9. Ask yourself
    When there’s a bug, how easy is it to find out which part of your code to fix?
  • 10. Want it testable? Make it SOLID!
  • 11. Single Responsibility Principle
    Your class should have one, and only one, reason to change
  • 12. Open Closed Principle
    You should be able to extend a class’s behavior without modifying it
  • 13. Liskov Substitution Principle
    Derived classes must be substitutable for their base classes
  • 14. Interface Segregation Principle
    Make fine grained interfaces that are client specific
  • 15. Dependency Inversion Principle
    Depend on abstractions, not on concretions
  • 16. Usability
    The ease with which people can employ a particular tool or other human-made object in order to achieve a particular goal
  • 17.
  • 18.
  • 19.
  • 20. Steve Krug’s First Law of Usability
