Exam 4: Requirements Modeling

In addition to helping to gather and analyze facts, many programs also automatically perform fact-finding for systems analysts.

Briefly describe the four phases of the rapid application development (RAD) model.

Compared with traditional methods, when properly used, joint application development (JAD) can result in _____.

When preparing a representative sample from a list of 200 customers who complained about errors in their statements, a _____ might select any 20 customers.

In addition to joint application development, another popular user-oriented method is _____, which resembles a condensed version of the entire SDLC with users involved every step of the way.

When designing a questionnaire, the most important rule of all is to make sure that questions collect the right data in a form that can be used to further the fact-finding effort.

To evaluate _____, a systems analyst needs information about projected future volume for all outputs, inputs, and processes.

A(n) _____, such as Microsoft Outlook, includes a private calendar, a to-do list, and powerful contact management features.

Matching ​Identify the letter of the choice that best matches the sentence or definition. -This provides various graphical tools, such as use case diagrams and sequence diagrams.

The personal interview usually is the least expensive fact-finding technique.

In the rapid application development (RAD) model, the _____ phase resembles the final tasks in the SDLC implementation phase.

One of the main activities in the systems analysis phase is _____, which involves fact-finding to describe the current system and identification of the specifications for the new system.

Due to the limited range of input and interaction among participants, few companies believe that a joint application development (JAD) group does not produce the best definition of a new system.

When designing a questionnaire, arrange questions in a random order, intermixing simple and more complex topics.

When conducting an interview, after asking a question, allow the person enough time to think about the question and arrive at an answer.

Matching ​Identify the letter of the choice that best matches the sentence or definition. -In determining this, one problem is that cost estimates tend to understate costs such as user support and downtime productivity losses.

In a sequence diagram, vertical arrows represent messages from one object to another.

Case 4-1 ​John has finished compiling a list of the various members of the joint application development (JAD) group and the list is as follows: John is the JAD project leader, Tom is the representative from top management, Jennifer is a manager, Alen and Ian are users, Linda and Alex are systems analysts, and Clark is the recorder. -As John develops the agenda, he wants to put the name of the appropriate person next to the agenda item. Whose name would he put next to the final task on the agenda, the task of documenting the results of the JAD session and preparing the report that will be sent to JAD team members?

Which of the following is a general category of system requirements?

Matching ​Identify the letter of the choice that best matches the sentence or definition. -If one of these is available, analysts can use it to develop models and enter documentation from the joint application development (JAD) session.
