Chapter One

1.1 With what other terminology is systems analysis and design synonymous?

Systems analysis and design is also known as information systems engineering, software engineering, systems engineering, software development, and systems development.

1.2 What activities and deliverables are included in analysis?

Activities: systems planning, feasibility study (optional), requirements determination, user acceptance,and prototyping (optional). Deliverables: Requirements specification and prototype (optional).

1.3 What activities and deliverables are included in design and implementation?

Activities: Physical design, prototyping (optional), software construction/purchase, user documentation, testing, training, user acceptance, conversion, and implementing the system. Deliverable: Information system.

1.4 Describe a system and the components of a systems model.

A generic systems model consists of six components- inputs, processes, outputs, controls, feedback, and boundary. Using predetermined controls, a system accepts inputs at its boundary, processes them into outputs, and provides a feedback mechanism for taking any necessary corrective action.

1.5 What two key components distinguish an information system from an automated information system?

Software and hardware.

1.6 How are data incorporated into an automated information system and what role does it play?

Data are either input, stored, or output. As part of the information system, data that are input and data that are stored are transformed or processed into meaningful output data called information.

1.7 How do the components of an information system relate and what is the purpose of each component?

In addition to having the six general system components, an information system has three additional components- people, procedures, and data. People interface in some
