An Introduction to Software Engineering (Part 1) Software engineering is the study of how to systematically and effectively develop software. Typically, the development of a medium to large-scale system involves the following stages: Project Initiation: Feasibility analysis, research, and review, resulting in Feasibility Analysis Report and Project Proposal; Initial System Design: Preliminary framework design based on feasibility, including hardware design, project approval, contract signing, and agreement on basic system framework, functionalities, system lifecycle, constraints, responsibilities, and obligations, resulting in Agreement, Hardware Solution, and Project Plan; Requirements Analysis: Project establishment, team formation, customer engagement, requirement research, and analysis, culminating in Requirements Analysis Report which serves as a reference for system acceptance, including business process diagrams and data flow charts; System Design: Includes database and system function design, abstraction and summarization of actual models into functional modules, resulting in System Design Report and Draft Functional Specification Document; System Implementation: Coding phase with interspersed testing and feedback, continuous client interaction for progress updates and evolving requirements; Testing Phase: Module-wise independent testing and integration testing, focusing on issues like boundaries, black-box, and stress testing, also including performance testing; resulting in Test Report and Correction Report, alongside documentation such as User Manual, Help Manual, and Quick Reference; Packaging: Rigorous testing and bug fixing, system is in a deployable state, requires creation of installation disks; Deployment: On-site data initialization, trial run phase, issue identification and resolution; resulting in Deployment Plan, Deployment Report, Requirement Changes, System Switch Preparation, and Switch Plan; Switch: After trial runs, system is ready for client use, transitioning into operational phase at the appropriate time; Monitoring: Close monitoring of system operation, immediate issue resolution; Post-Maintenance: Patching and bug fixing operations.
