Exam 5: System Design and Acquisition

Explain what is meant by the process perspective.

The _________ perspective of system modeling focuses on organizational data but is not be concerned with how the data are used within the organization

A logical model of the system graphically illustrates what the system does, independent of any technological architecture (e.g.hardware, software, networking, etc.).

Using an Application Service Provider (ASP)is a software acquisition strategy where ready-made software is purchased and installed on the organization's local network.

Base design is a phase in the SDLC in which a new system is designed without regard to the technology (e.g.hardware, software, networking, etc.)in which it will be implemented.

Which model - the physical or logical - is more useful in designing the HRIS?

A Data Flow Diagram (DFD)is a statistical tool which can be used to manipulate or change the data.

The strength of using _________ is that the HR staff and developers can focus specifically on business processes, policies, and procedures instead of on technology, leading to stronger solutions.

Economic Feasibility is a feasibility assessment tool that focuses on the financial and economic benefits and costs which a new system would bring to the organization.

Logical design describes a phase in the SDLC in which a new system is designed with particular focus on how the hardware, software, networking, activities, users, etc.will be implemented.

Operational Feasibility is a tool that focuses on how well the new system will fit within the organization, including issues such as development schedule, extent of organizational change, and user responses to the system.

In a DFD, processes are the mechanism through which data is transformed, manipulated, created, etc.into output such as a report, a decision, etc.

The goal of __________ feasibility analysis is to determine whether the costs of developing, implementing, and running the system are worth the benefits derived from its use.

What is meant by a process view of a system?

What is a physical model of an HRIS?

A context level diagram is used to represent the system, its boundary and the external entities which interact with the system.

A(n)________________ solicits proposals and bids for proposed work from potential consultants or vendors and defines the organization's goals and requirements for the new HRIS.

Logical feasibility is a system feasibility assessment tool that focuses on the technical capability of the organization and the availability of the technology necessary to implement a new system.

A single data flow diagram typically is all that is typically needed when discussing data flow.
