Exam Name___________________________________ TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 1) Proper and insightful project planning, including determining project scope as well as identifying project activities, can easily reduce time in later project phases. 1) _______ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 2) The Baseline Project Plan: 2) _______ A) contains all information collected and analyzed during project initiation and planning B) is used by the project selection committee to help decide if the project should be accepted, redirected, or canceled C) specifies detailed project activities for the next life cycle phase, analysis, and less detail for subsequent project phases D) all of the above 3) When conducting a technical risk assessment, which of the following is true? 3) _______ A) Successful IS projects require active involvement and cooperation between the user and development groups. B) Large projects are riskier than small projects. C) A project has a greater likelihood of experiencing unforeseen technical problems when the development group lacks knowledge related to some aspect of the technology environment. D) all of the above 4) Questions in interviews asking those responding to choose from among a set of specified responses are: 4) _______ A) specific questions B)

structured questions C) closed - ended questions D) open - ended questions 5) In the Gane and Sarson model, a rectangle with rounded corners on a data flow diagram represents a: 5) _______ A) data store B) data flow C) source/sink D) process 6) When you believe that you have shown each business form or transaction, computer screen, and report as a single data flow, you have probably reached the: 6) _______ A) primitive data flow diagrams B) level - 0 diagrams C) level - 3 diagrams D) level - 1 diagrams 7) Which of the following depicts the interactions among objects during a certain period of time?

7) _______ A) data flow diagrams B) collaboration diagrams C) class diagrams D) sequence diagrams 8) Some systems developers believe that a data model is the most important part of the statement of information system requirements because: 8) _______ A) data rather than processes are the most complex aspects of many modern information systems and thus require a central role in structuring system requirements B) the characteristics of data captured during data modeling are crucial in the design of databases, programs, computer screens, and printed reports C) the characteristics about data are reasonably permanent D) all of the above 9) Which of the following is a true statement? 9) _______ A) Data characteristics are dynamic. B) An information system design based on a data orientation, rather than a process or logic orientation, should have a longer useful life. C) A data model explains the transient form of an organization. D) Data flow paths are permanent. 10) The most common format used for data modeling is:

10) ______ A) decision table diagramming B) entity - relationship diagramming C) state - transition diagramming D) process modeling 11) During requirements structuring: 11) ______ A) the conceptual E - R data model is refined before it is translated into a logical format from which database definition and physical database design are done B) a specific E - R model is built to help explain the scope of a particular systems analysis and design effort C) an enterprise - wide data model with very broad categories of data and little detail is prepared D) an E - R model represents conceptual data requirements for a particular system 12) Conceptual data modeling is typically done in parallel with other requirements analysis and structuring steps during: 12) ______ A) logical design B) implementation C) analysis D) physical design 13) Process, logic, and data model descriptions of a system must be consistent and complete because:

13) ______ A) programming tasks require the integration of the information contained in the diagrams B) they each describe different but complementary views of the same information system C) they are prepared during the analysis phase D) they are constructed in parallel by separate analyst teams 14) An E - R model with attributes is prepared during: 14) ______ A) design B) project initiation and planning C) project identification and selection D) analysis 15) The primary deliverable from the conceptual modeling step within the analysis phase is a(n): 15) ______ A) context data flow diagram B) decision tree C) E - R diagram D) state - transition diagram 16) The data modeling perspective that derives the business rules for a data model from an intimate understanding of the

nature of the business, rather than from any specific information requirements in screens, reports, or business forms, is referred to as the: 16) ______ A) business approach B) top - down approach C) overview approach D) bottom - up approach 17) The three main constructs of the entity - relationship modeling notation include each of the following except: 17) ______ A) data entities B) relationships C) data flows D) attributes 18) A detailed, logical representation of the entities, associations, and data elements for an organization or business area defines: 18) ______ A) conceptual model B) data flow diagram C) entity - relationship model
