Project Management Concepts

Using a work breakdown structure (WBS) allows one to manage a project as one large task.

A Pareto chart, sometimes called a scatter diagram, is primarily a problem-solving tool.

The purpose of an interview and of the preliminary investigation itself is to convince others that a project is justified, not to uncover facts.

System software controls the flow of data, provides data security, and manages network operations.

In a knowledge management system, a knowledge base consists of logical rules but identifies data patterns and relationships.

A software PEERT or CPM stands for "Predical Pact Method," and Gantt charts are mutually exclusive techniques.

A system dev can initiate a formal project as soon as the preliminary investigation stage or later on as analysis, design, and implementation occur.

Review Technique Critical Path Method.

Purpose of quantitative risk analysis.

An information system's data is information that has been transformed into a variable.

If the project manager fails to plan, staff, organize, communicate, motivate, and evaluate, the project is certain to fail.

Feasibility analysis is an ongoing task that must be performed throughout the business development process.

Accessibility analysis is an ongoing task throughout the project.

The responsibilities of a systems analyst at a small firm are exactly the same as those at a large corporation.

A mission-critical system is one that is unimportant to a company’s operations.

In an information system, data is information that has been transformed into input that is valuable to users.

User support provides users with technical information, training, and productivity support.

When planning an information system, a company must consider how a new system will interface with older systems, which are called horizontal systems.

Hardware consists of everything in the physical layer of the information system.

Examples of company-wide applications, called legacy applications, include order processing systems, payroll systems, and company communications networks.

Transaction processing (TP) systems are inefficient because they process a set of transaction-related commands individually rather than as a group.

A large concentration of networked computers working together is called a data ranch.

Application software consists of programs that support day-to-day business functions and provide users with the information they need.

Most large companies require systems that combine transaction processing, business support, knowledge management, and user productivity features.

Many companies find that a trend called empowerment, which gives employees more responsibility and accountability, improves employee motivation and increases customer satisfaction.

Assistive technology refers to the combination of hardware, software, and services that people use to manage, communicate, and share information.

Since middle managers focus on a longer time frame, they need less detailed information than top managers, but somewhat more than supervisors who oversee day-to-day operations.

Network administration includes hardware and software maintenance, support, and security.
