Course Overview
This lesson introduces students to the structured process of systems analysis and design, which is essential for developing effective computer-based information systems. It begins by explaining what a system is and the importance of analyzing existing systems to understand their components, processes, and limitations.
Students will explore the phases of the system development life cycle (SDLC)—including problem identification, feasibility study, system analysis, design, implementation, testing, deployment, and maintenance.
The lesson covers key tools and techniques used in system analysis, such as data flow diagrams (DFDs), context diagrams, and entity-relationship diagrams (ERDs). It also explains different system development methodologies such as the waterfall model and agile development.
By the end of this lesson, students will be able to:
-
Understand the purpose and importance of systems analysis and design.
-
Identify and describe each phase of the SDLC.
-
Use analysis tools like DFDs, context diagrams, and ERDs.
-
Compare system development methodologies.
-
Apply systematic thinking to solve real-world problems through system design.
This lesson prepares students for software development and IT project management by developing their analytical and design skills.
