• Design
  • Architects think about the components needed to implement the plan
• Implementation
  • Programmers execute the plan
• Testing
  • Validate parts of the code
• Deployment
  • General Availability
• Maintenance

Software Development Models

• Waterfall Methodology
• Agile Methodology
• Spiral Methodology
• Rapid Application Development (RAD) Methodology
• The V Methodology
• The Big Bang SLDC Methodology
