The document summarizes the key stages in system analysis: 1. The analysis stage involves collecting data on the current system, identifying problems, and agreeing on customer requirements. A feasibility study is also conducted. 2. In the design stage, data capture forms, screen layouts, and reports are designed. Hardware and software requirements are also selected. 3. The development stage finalizes the file structure and fully tests the system before implementation. Validation and verification ensure the correct data is stored.
