Exam 5: Systems Analysis

A nonfunctional requirement is a description of other features, characteristics and constraints that define a satisfactory system.

__________________________ defines the boundary of the project - those aspects of the business that will and will not be included. 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.

The feasibility analysis should be stopped as soon as the analyst identifies an ideal solution. This will save valuable time that can be put to better use during the implementation phase.

A __________________________________ defines the project scope, plan, methodology, and standards for a project. It is the first major milestone.

The requirements analysis phase answers the question, "What do the users need and want from a new system?"

A mandatory requirement is one that is essential for the system, but not necessaryily for the first version of the system.

Security is an example of a functional requirement.

In the future, with the improvement of CASE tools, we will no longer need systems analysts to investigate business problems; the procedure will be completely automated.

Cause-and-effect analysis is an out-of-date technique that is unnecessary today given the complete nature of the scope definition phase that makes such problems and their solutions obvious.

The study of a current business and information system application and the definition of user requirements and priorities for a new or improved information system is part of which phase?

The PIECES framework can be used to categorize problems, opportunities, directives, and constraints.

Requirements discovery is the process of identifying system problems and solution requirements from the user community.

____________________________________ technology reads the program code for an existing database, application program, and/or user interface and automatically generates the equivalent system model.

Systems design is a complementary problem solving technique to systems analysis that reassembles a system's component pieces into a (hopefully improved) complete system.

All desirable requirements should be included in version 1.0.

Business process redesign is often applied within the context of information systems development when the projects include a study of existing business processes to identify problems, bureaucracy and inefficiencies that need to be addressed in requirements for new and improved information systems.

CASE tools offer the advantage of consistency and completeness analysis as well as rule-based error checking.

The _____________________________phase typically includes the following tasks: (1) study the problem domain; (2) analyze problems and opportunities; (3) analyze business processes; (4) establish system improvement objectives; (5) update the project plan; (6) present findings and recommendations.

An agile method integrates various approaches of systems analysis and design..

Cause-and-effect analysis leads to true understanding of problems and can lead to not-so-obvious, but more creative and valuable solutions.
