Which model is an example of a sequential approach that visualizes key SE focus areas by mapping development stages to corresponding testing/production stages?

• A. Waterfall Model
• B. Evolutionary Approach
• C. Vee model
• D. Incremental Approach

Answer: (C)

Visualizing verification and validation as a guided, left-to-right progression is the idea behind this model. It is a sequential approach where each development activity on the left—capturing requirements, doing high-level design, architectural design, and module design—has a corresponding testing or validation activity on the right: system verification, integration testing, unit testing, and acceptance testing. This creates a V shape that clearly links what you build to how you prove it meets requirements and will operate in its intended environment. By aligning each design step with a matching test step, you ensure every decision is validated and verified as you move toward deployment. Other models describe linear progress or emphasize iteration, but they don’t provide the same explicit one-to-one mapping between development stages and their testing/validation counterparts that defines this approach.
