    Study Notes

    • Systems development involves producing additional deliverables, such as design documents, reports, and project meetings, in addition to the final information system.

    • Systems Development Lifecycle (SDLC) consists of phases: Initiation, Analysis, Design, Development, and Maintenance.

    • The waterfall model is a classic SDLC approach, but it can be limiting for large projects where each stage can take extended periods.

    • Prototyping is an alternative approach, involving the development of a small part of the system at a time, with subsequent iterations and improvements.

    • Content piracy is a problem costing the US economy $58 billion annually, with solutions including search engine algorithms to prevent pirated content and new IT-enabled products to compete with pirated content.

    • Information systems raise ethical questions due to their potential for social change, new types of crime, and the five moral dimensions of the information age: information rights, property rights, accountability, system quality, and quality of life.

    • Ethical principles to guide decisions include the Golden Rule, Immanuel Kant's Categorical Imperative, Descartes' Rule of Change, Utilitarian Principle, Risk Aversion Principle, and Ethical "No Free Lunch" Rule.

    • The Association of Computing Machinery (ACM) and other professional organizations establish codes of conduct for their members.

    • Privacy and intellectual property rights exist in the digital age, with regulations like the Data Protection Act and the European Directive on Data Protection aiming to protect personal information and regulate its use.
