System Fundamentals

We are concerned with how systems integrate into organizations and how people use them.

The big ideas in system fundamentals

Systems in Organizations

A computer program or computer system is used by people who work in organizations. It is very helpful to understand how people, computers, and organizations work together.

System Design

Components of a computer system

• Hardware, software, peripheral, network, human resources
• Computers in a networked world
• Ethics

System Design and analysis

• Planning and stakeholder involvement
• Getting requirements from stakeholders
• Gathering information for solutions
• Illustrate system requirements
• Prototypes

Planning and system installation

• System planning
• Change management
• Legacy system
• Testing
• Implementation methods
• Data migration

User Focus

• User documentation
• User training

System Backup

• Data loss and preventing data loss

Software Deployment

• Managing releases and updates

Human interaction with the system

• Usability
• Problems with usability
• Improve the accessibility of a system
• Moral, ethical, social, economic and environmental implications of the interaction between humans and machines (see also ethics)

• Discuss the moral, ethical, social, economic and environmental implications of the interaction between humans and machines.

Produce a plan, simulation or model.

Provide an answer from a number of possibilities. Recognize and state briefly a distinguishing fact or feature.

The circumstances that form the setting for an event, statement, or idea, and in terms of which it can be fully understood and assessed.

Give a detailed account or picture of a situation, event, pattern or process.

Give a brief account.
