Software Development

1. Software Development Life Cycle Model

   • Requirements
     • the needs of the company are outlined
   • Implementation
     • to meet the design outlined in the design phase.
   • Testing
     • plan is created to describe the unit tests
   • Design
     • the designers attempt to turn the dreams of the managers and users into reality.

   • Advantages of the Spiral model
     • ideal for large-scale and missioncritical
     • software code is developed early
   • Disadvantages of the Spiral model
     • The Spiral model is inappropriate for use in small and medium-scale projects that are not mission-critical.

3. Waterfall Life Cycle Model

   • Advantages of the Waterfall model
     • Appropriate for small development projects
     • simple and easy to use
   • Disadvantages of the Waterfall model
     • Inappropriate for complex projects.
     • Not be used for developing object-oriented

4. V-Shaped Life Cycle Model

   • Advantages of the V-Shaped model
     • appropriate for small development projects
     • The focus on preparing test plans
   • Disadvantages of the V-Shaped model
     • Inappropriate for most projects.
     • Inappropriate for complex projects.

5. Incremental Life Cycle Model

   • Advantages of the Incremental model
     • More flexible when adding or changing requirements
     • This model is also easier to test and debug
   • Disadvantages of the Incremental model
     • Cannot be overlapped.
