Test Bank Chapter 1: Systems Analysis Midterm 1

Environment refers to...

... everything external to a system that interacts with the system

Coupling is the...

... extent to which subsystems depend on each other.

Systems analysis is the...

... phase of the SDLC in which the current system is studied and alternative replacement systems are proposed.

Modularity is the...

... process of dividing a system into chunks or modules of equal size

The systems development life cycle is the...

... series of steps used to mark the phases of development for an information system.

An interface is...

... the point of contact where a system meets its environment or where subsystems meet each other.

Joint Application Design is....

.... a structured process in which users, managers, and analysts work together for several days in a series of intensive meetings to specify or review system requirements.

Prototyping refers to....

.... building a scaled-down version of the desired information system

Systems planning and selection is the...

.... first phase of the SDLC, in which an organization's total information system needs are analyzed and arranged, and in which a potential information systems project is identified and an argument for continuing or not continuing with the project is presented.

Systems design is the...

.... phase of the SDLC in which the system chosen for development in systems analysis is first described independently of any computer platform and is then transformed into technology-specific details from which all programming and system construction can be accomplished.

Interrelated components refers to...

....a dependence of one part of the system on one or more other system parts.

a boundary is....

...The line that marks the inside and outside of a system and that sets off one system from other systems in the organization

The purpose is...

...The overall goal or function of a system

A system is...

...a group of interrelated procedures used for a business function, with an identifiable boundary, working together for some purpose.

A constraint is...

...a limit to what a system can accomplish.

A component is....

...an irreducible part or aggregation of parts that makes up a system.

Cohesion is the....

...extent to which a system or subsystem performs a single function.

Decomposition is...

...the process of breaking the description of a system down into small components.

Information systems analysis and design is...

...the process of developing and maintaining an information system.

A boundary is the point of contact where a system meets its environment or where subsystems meet each other.

False

An enterprise resource planning system is one of the three information systems classes.

False

An interface separates a system from other systems.

False

Cohesion is the extent to which subsystems depend on each other.

False

Cohesion is the process of breaking down a system into its smaller components.

False

Coupling is a direct result of decomposition.

False

Coupling results in smaller and less complex systems that are easier to understand than larger, complicated systems.

False

Systems analysis is the first phase of the systems development life cycle.

False

The systems development life cycle is a sequentially ordered set of phases.

False

A system's capacity can be viewed as a system constraint.

True

A system's environment is everything outside a system's boundary that influences the system.

True

Decomposition allows the systems analyst to build different parts of the system at independent times and have the help of different analysts.

True

Enterprise-wide systems are large, complex systems that consist of a series of independent system modules.

True

Information technology services firms, packaged software providers, vendors of enterprise-wide solution software, open-source software, and in-house development are sources of software.

True

Interfaces exist between subsystems.

True

Involving the user in analysis and design is a key advantage to the prototyping technique.

True

Joint Application Design (JAD) is a structured process in which users, managers, and analysts work together for several days in a series of intensive meetings to specify or review system requirements.

True

Modularity divides a system into chunks or modules of a relatively uniform size.

True

The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently.
