Exam 1: The Systems Development Environment

Current approaches to systems development that focus on adaptive methodologies, people instead of roles, and an overall self-adaptive development process best defines:

An information system interacts with its environment when it processes data.

During operation, programmers make the changes that users ask for and modify the system to reflect changing business conditions.

Rapid application development (RAD) sacrifices human efficiency when rapidly building and rebuilding working systems.

Building a scaled-down version of the desired system best describes:

A key principle of the Agile Methodologies is a clear focus on people rather than roles.

Your primary responsibility as a systems analyst concerns:

Match each of the following system characteristics with its corresponding description. -Point of contact where a system meets its environment or where subsystems meet each other

Describe the term component as related to systems.Discuss how components can work together.

Match each of the following terms with its corresponding definition. -Building a scaled-down version of the desired information system

The extent to which a system or subsystem performs a single function defines:

Match each of the following system characteristics with its corresponding description. -Everything external to a system that interacts with the system

Describe the role of a systems analyst.

Component focusing allows the systems analyst to break a system into small, manageable, and understandable subsystems.

Match each of the following system characteristics with its corresponding description. -An irreducible part or aggregation of parts that make up a system

Match each of the following SDLC phases with its corresponding definition. -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

The extent to which subsystems depend on each other refers to:

The process of developing and maintaining an information system best describes:

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

Modularity is a direct result of decomposition.
