       4. Define the requirements, develop the prototype, revise and enhance the prototype

1. 21. When systems are created rapidly, without a formal development methodology:
       1. end users can take over the work of IT specialists.
       2. the organization quickly outgrows the new system.
       3. hardware, software, and quality standards are less important.
       4. testing and documentation may be inadequate.

C) Prototyping                   D) End-user development

1. 28. The term structured, when discussing structured methodologies, refers to the fact that:
       1. the finished software is highly documented.
       2. the development process is highly documented.
       3. the techniques are step by step, with each step building on the previous one.
       4. a defined hierarchy of objects and classes are used to structure the programming.

       4. data flow diagram.

1. 30. You are an IT project manager for an advertising firm. The firm wishes to create an online survey tool that will be used to survey focus group reactions to products in development. The most important consideration for the firm is being able to offer the tool as soon as possible as a new corporate service. However, you know that many of the senior managers that are business owners of this project have difficulty in understanding technical or software development issues, and are likely to change their requirements during the course of development. What development method would be most successful for this project?
       1. RAD                                                  B) JAD

C) End-user development            D) Prototyping

       1. structure charts.
       2. Gantt charts and PERT.
       3. process specifications diagrams.
       4. data flow diagrams.

1. 32. An entire information system is broken down into its main subsystems by using:

       1. Degree would be a sister class to Mathematics and Physics.
       2. Degree is a superclass to Mathematics and Physics.
       3. Mathematics and Physics would be ancestors to Degree.
       4. Degree would be a subclass to Mathematics and Physics.

       1. objects and relationships.
       2. classes and objects.
       3. class and inheritance.
