This assignment solution addresses the ICT581 Information Systems Principles and Practice Tutorial 3, focusing on information systems analysis and design. The solution begins by identifying the information systems used by AgriDigital, including Sage for payroll and human resources, Google Data Studio for reporting and dashboards, and IPTIM for strategic planning. It classifies these systems as TPS (Quickbooks example), MIS (Sage), DSS (Data Studio), and EIS (IPTIM), explaining the rationale behind each classification. The solution also covers system development, outlining the key activities within the system development life cycle (SDLC), such as preliminary analysis, system analysis, system design, development, deployment, maintenance, and disposal. Furthermore, it defines the role of a systems analyst, emphasizing their systematic assessment of user interactions with technology and business operations to improve input, processing, and output. References to relevant literature are included.
