Many new systems are built primarily by integrating operating systems, communication systems, and applica- tions into a single system. ____ 3. Adaptive approaches to system development do not allow for uncertainly. ____ 4. Empirical control works well when more planning can provide more detail. ____ 5. The only way to develop code quickly is to do it in small chunks and to develop the system incrementally. ____ 6. Adopting an agile approach for a project is relatively easy. ____ 7. Managers and stakeholders frequently struggle to accept a chaordic point of view for system development. ____ 8. In Agile Development, contracts include options for the customer to cancel if the project is not progressing, as measured by the incremental deliverables. ____ 9. Agile Modeling emphasizes creating only models that are necessary. ____ 10. In Agile Modeling, change is seen as the exception, not the norm. ____ 11. Agile Modeling principles suggest that CASE tools should be used whenever possible. ____ 12. An Agile Modeling practice used in incremental modeling is to create several models in parallel. ____ 13. Maintaining simplicity in Agile Modeling eliminates the need for validating the models with code. ____ 14. The quality of the code is always higher in a pair-programming environment. ____ 15. In XP, each programmer is responsible for her or her own code. ____ 16. XP recommends that system code be written before test code. ____ 17. The Scrum master sets the project schedule and assigns tasks. ____ 18. Once a Scrum team has agreed on a goal and has selected items from the backlog list, the scope of the sprint is frozen. ____ 19.

____ 28. Java is an OO programming language developed by Sun Microsystems. ____ 29. JavaBean components are platform independent. ____ 30. When deploying component-based software in a distributed environment, network and server capacity should be upgraded prior to development and testing. ____ 31. In the UP life cycle, some working software is tested and reviewed with system users at the end of each itera- tion. ____ 32. The elaboration phase of the UP is usually completed in one iteration. ____ 33. The UP should not be tailored to the needs of a specific organization or system project. ____ 34. Most iterations in the UP involve work in all disciplines. ____ 35. The Unified Process (UP) life cycle has four phases: inception, elaboration, construction, and transition.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
