V shapes verification and validation model of software development

Description:

The image is a PowerPoint slide titled "V Shapes Verification and Validation Model of Software Development". This model is widely used in the software engineering industry to visualize the process of software development, emphasizing the verification and validation of each stage. The V-model illustrates how each phase must be completed before the next begins, and testing is planned in parallel with corresponding development activity.

1. User Requirements:

This phase involves gathering the needs and requirements from the user's perspective.

2. Software Specification:

Specifications are drawn up to define the software functions based on user requirements.

3. High-Level Design:

This stage focuses on system architecture and overall design.

4. Low-Level Design:

Detailed designs of software components are created.

5. Coding:

The actual writing of code based on the design documents.

6. Unit Testing:

Individual units or components of the software are tested to ensure they work properly.

7. Integration Testing:

Different software modules are combined and tested as a group.

8. System Testing:

The complete integrated software system is tested to validate that it meets all specifications.

9. Acceptance Testing:

The final testing phase where the software is tested for acceptability to ensure it delivers the needed solution.
