    Answer All Questions (Use scan card):

    True or False Questions. Circle 'A' if the statement is true and 'B' for false:

    ____ 1. While prioritizing requirements, the project manager precisely defines the functions that will

    be included in the project and sets a baseline, which he/she can use to control and direct the rest of the project.

____ 2. Custom-built systems require minimal programming by in-house staff or outsourced consultants and

    programmers.

    ____ 3. The decision regarding whether or not the system is to be outsourced is usually made by a project team.

    ____ 4. One critical problem with turnkey systems is that they often do not exactly meet the needs of the organization.

____ 5. Usually, it is more difficult for an analyst to define high-end automation than low-end automation because

    low-end automation is basically an automated version of a current manual procedure.

____ 6. Important technical issues arise when making the system operate over a network, such as reliability, security,

    throughput, and synchronization.

____ 7. Designing the application architecture involves specifying in detail how each system activity will actually be

    carried out.

____ 8. To start the design process, the analyst partitions the entire system into its major components, because an

    information system is much too complex to design at once.

____ 9. Analysis and modeling require very limited user involvement to explain the requirements and to verify that

    the models are accurate.

____ 10. The objective of the design phase is to define, organize, and structure the components of the final solution

    system that will serve as a blueprint for construction.

____ 11. A structure chart forces the program functions to be in a hierarchy.

    ____ 12. Data couples represent the individual data items that are passed between modules in a program call.

____ 13. The central transform consists of the set of DFD processes that are located between the input and output

    processes.

    ____ 14. Pseudocode and flow charts are equivalent methods in their ability to describe logic.

    Short Answer Questions:

1. What is the difference between scope and level of automation? (4 points)

     Scope is determined by the list of functions that are included in a system. Level of

    automation is the amount of computer sophistication and support provided for each function.

2. What is the difference between general requirements, technical requirements, and functional

    requirements? (6)

    General requirements include considerations that are important but that are not directly

    associated with the computer system itself. General requirements include the track record and

    reputation of the vendor.

    Technical requirements are the technical constraints imposed on the system, such as response time,

    operating platform, and database system.

    Functional requirements identify the specific business functions that must be provided by the new

    system.

    3. What is the difference between analysis and design? List the activities of the design phase of the SDLC.

    ( 6 points)

    Analysis is for discovery and understanding. Its purpose is to develop requirements. Design

    is for structuring and developing a solution. While analysis looks at problem issues and the

    problem domain, design looks at solution issues and the solution system.

    The activities of the design phase of the SDLC include:

    ? Design and integrate the network.

    ? Design the application architecture.

    ? Design the user interfaces.

    ? Design the system interfaces.

    ? Design and integrate the database.

    ? Prototype for design details.

? Design and integrate the system controls.
