test 1 true/false

A Network diagram depicts project tasks and their interrelationships.

true

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

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

Most techniques for analyzing economic feasibility employ the time value of money concept.

true

Opening new markets and increasing sales opportunities is a tangible benefit.

true

Outsourcing refers to turning over responsibility of some or all of an organization's information systems applications and operations to an outside firm.

true

Site preparation is an example of a one-time cost.

true

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

false

A major disadvantage of the Network diagram is its inability to represent completion times and show interrelationships between activities.

false

An activity on the critical path will have a slack time of 1.

false

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

false

An interface separates a system from other systems.

false

Cloud computing is best when a supported task is generic and one does not need instant access.

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

Increased flexibility is an example of an intangible benefit.

false

One of the primary benefits of using an enterprise software solution is the short time period required for implementation.

false

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

false

The Project Charter reflects the best estimate of the project's scope, benefits, costs, risks, and resource requirements, given the current understanding of the project.

false

The objective of return on investment (ROI) analysis is to discover at what point cumulative benefits equal costs

false

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

false

Variable costs are costs resulting from the ongoing evolution and use of a system.

false

Using enterprise software solutions, a firm can integrate all parts of a business process in a unified information system.

true

Because many projects may be competing for the same investment dollars and may have different useful life expectancies, all costs and benefits must be viewed in relation to their present rather than future value when comparing investment options

true

Critical path scheduling is a scheduling technique whose order and duration of a sequence of task activities directly affect the completion date of a project.

true

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

true

Economic feasibility is a process of identifying the financial benefits and costs associated with a development project.

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

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.

true

The project manager is responsible for initiating, planning, executing, and closing down the project.

true

The time value of money (TVM) compares present cash outlays to future expected returns.

true
