Software Development Life Cycle (SDLC) and High Quality Software Systems, Slides of Software Engineering
An overview of the software development life cycle (sdlc) and the concept of high quality software systems. It covers the phases of sdlc, including initiation and planning, requirement gathering and analysis, design, implementation, testing, maintenance, and retirement. The document also discusses different sdlc models such as waterfall, v-model, evolutionary prototyping, and spiral. Additionally, it touches upon the importance of security considerations in software engineering.

What is a “High Quality” System?
• Satisfies requirements
• Sophisticated
• Structured
• Supports abstraction
• Reusable
• Documented
SDLC
- Finite and definite period of time
- Starts: when the SW product is conceived
- Ends: when the SW is no longer used or available
- SDLC is composed of phases
SDLC Models
• Waterfall (enhanced waterfall)
• V-model
• Evolutionary prototyping
• Rapid prototyping
• Spiral
• Reuse oriented
• Formal
