Study Notes

Information Systems Analysis and Design (SAD) is a structured method used to create and maintain systems that improve employee efficiency by applying software solutions to key business tasks.
Systems Analysts perform SAD by understanding an organization's objectives, structure, processes, and leveraging information technology for an advantage.
The core goal of Systems Analysis and Design is to enhance organizational systems by developing or acquiring application software, providing training, hardware, system software, documentation, job roles, controls, and interfaces.
A system is an interrelated set of business procedures within a business unit that turns data into information, with components like purpose, environment, boundary, interrelationships, constraints, interfaces, input, and output.
Important system concepts include decomposition (breaking down a system into smaller components), modularity (dividing a system into modules), coupling (desired loose coupling between subsystems), and cohesion (high cohesion where subsystems perform a single function).
Systems Integration enables hardware and software from different vendors to work together, using a visual programming environment with a client/server model.
The Systems Development Life Cycle (SDLC) involves phases like systems planning and selection, systems analysis, system design, and system implementation, operation, and maintenance; alternative approaches include prototyping, Joint Application Design (JAD), Rapid Application Development (RAD), and Agile Methodologies.
