System Fundamentals[1]
We are concerned with how systems integrate into organizations and how people use them. You ignore this at your peril!
The big ideas in system fundamentals[edit]
Systems in Organizations[edit]
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.
Planning and system installation[edit]
User Focus[edit]
System Backup[edit]
- Data loss and preventing data loss
Software Deployment[edit]
System Design[edit]
Components of a computer system[edit]
System Design and analysis[edit]
- Planning and stakeholder involvement
- Getting requirements from stakeholders (see also design process)
- Gathering information for solutions (see also design process)
- Illustrate system requirements (see also design process)
- Prototypes (see also design process)
Human interaction with the system[edit]
- Usability
- Problems with usability
- Improving usability
- Moral, ethical, social, economic and environmental implications of the interaction between humans and machines (see also ethics)
Standards[edit]
