Exam 5: Systems Analysis

A diagram that depicts how the system interacts with the world around it and specifies the system inputs and outputs is a(n):

Which of the following are not in the classical set of techniques for fact-finding?:

Developing the baseline schedule and budget is the responsibility of the system owner.

Model driven analysis emphasizes the drawing of pictorial system models to document and validate both existing and/or proposed systems. Ultimately the system model becomes the blueprint for designing and constructing an improved system.

The problem analysis phase typically includes the following tasks: (1) understand the problem domain; (2) analyze problems and opportunities; (3) analyze business processes; (4) establish system improvement objectives; (5) update or refine the project plan; (6) communicate findings and recommendations.

In the scope definition phase, __________________________ is used to assess the degree to which a project solution or new system would be visible to customers and/or executive management.

Objectives fall into four categories: schedule, cost, technology and policy.

In the scope definition phase, possible solutions are expressed in simple terms to facilitate high level-discussion of options such as (a) leave well enough alone; (b) a quick fix; (c) a simple to moderate enhancement of the system; (d) redesign the existing system, or (e) design a new system.

In the scope definition phase, possible solutions need to be expressed in as much detail as possible so that an accurate picture of the feasibility of the project can be determined.

A committee of executive business and system managers that studies and prioritizes competing project proposals to determine which projects will return the most for an organization, and should be approved is:

Scope can change during the life cycle of a project, however, the initial project plan needs to establish the preliminary scope to provide a context for the budget and schedule.

Information engineering (IE) is a data-driven, process-centered, but model-sensitive technique to plan, analyze and design information systems.

Agile methods often require more modeling than other methods.

The deliverables of the problem analysis phase include an understanding of the problem domain and business vocabulary.

_________________________________ fall into four categories: schedule; cost; technology; and policy.

Prototyping is an alternative to system modeling.

Joint requirements planning (JRP) techniques use facilitated workshops to bring together all the system owners, system users, systems analysts and some systems designers and builders to jointly perform systems analysis.

A(n) __________________________ is a location (or set of locations) where systems analysts,systems designers and system builders keep the documentation associated with one or more systems or projects.

Examples of fact-finding techniques include: sampling of existing documentation; research of relevant literature; observation of the current system; questionnaires and surveys of the management and user community; and interviews of appropriate managers, users, and technical staff.

Technical feasibility asks the following question(s):
