06 - RAD

 1. RAD (Rapid Application Development) offers a solution by enabling systems to be developed in a much …………………... frame, often less than six months from start to finish.

  slower time

  more neutral

  more creative

  faster time

 2. The following approach(es) can be used in RAD:

  Use prototyping to refine the system with heavy involvement of the user

  All of the above

  Allocate strict time limits to develop each part - the intent is to make a system that is good enough (not all bells and whistles)

  Use workshops and focus groups to gather requirements rather than a formal requirement document

 3. A rather common problem with system development is that there may be a very long delay from when the idea of a new system is first suggested to when development begins.

  TRUE

  FALSE

 4. A prototype represents some aspect of the full system - for instance a …………….

  fully functional graphical user interface with every bell and whistle imaginable

   mock-up (design and UI but not all functional)of the graphical user interface.

  All of the above

  corrupted user interface, which will show the user the types of errors they will face

 5. In a prototype GUI, the user would click on command buttons and see its effect. That button is …………………………...but is programmed by the developer to act as if it was.

  not actually connected to a real system

  not connected to the CPU, but rather onlhy to the operating system

  is created by robots and not humans

  connected to a real system

 6. A prototype will help the user to see how the real system will work and ………………… before the developer puts even more work into it.

  highlight all the possible errors that could go wrong with the final system

  make changes

  None of the above

  delete the whole system

 7. A prototype is a fully working system and it allows the user to suggest feedback and make suggestions

  TRUE

  FALSE

 8. Prototyping in RAD is an 'iterative' process. Why?

  because feedback may be given again and again until both the user and the developer are agreed and satisfied

  None of the above

  because programmers that use prototypes have to use loops in their code

  It is not an iterative process. Protoyping and RAD is a one-off single process.

 9. Generally speaking, it is much cheaper to build a prototype and deal with issues, rather than create the whole system and find out the problems at the end.

  FALSE

  TRUE

 10. The two types of prototypes are:

  evolutionary and throw-away

  CPU-based and OS-based

  initial and final

  starting and ending

 11. The advantages of RAD include:

  All of the above

  Fewer late changes and better quality user requirements (user feels ownership)

  Greater user satisfaction (much involvement with the user)

  Speed of development

 12. The idea behind RAD is to ………………………….rather than getting an analyst to collate everything to produce a requirements document.

  not involve anyone, except the developer

  not involve the user so they can be free

  involve the public (i.e all possible test users)

  involve the user

 13. In RAD, each task does not have to be set a strict time limit - time is very flexible in RAD which helps both parties.

  FALSE

  TRUE

 14. Speed is important in RAD so the use of software libraries, existing frameworks and re-using code is often employed.

  TRUE

  FALSE

 15. The following is an advantage of RAD: 
Users are not expected to understand everything they require at the beginning of the project. Requirements evolve.

  TRUE

  FALSE
