The simplest model in software development is _____.

Correct option is D

The Waterfall model is considered the simplest software development model. It follows a linear sequential approach, where each phase (e.g., requirements, design, coding, testing) is completed before moving to the next.
Important Key Points:
1. Linear Approach: The Waterfall model is straightforward, making it easy to implement and understand.
2. Fixed Phases: Phases like requirements gathering, system design, implementation, and testing are distinct and sequential.
3. Best for Simple Projects: Ideal for projects with clearly defined requirements and no expected changes.
Knowledge Booster:
· Iterative Model: Involves repeating development cycles.
· Spiral Model: Combines iterative development with risk analysis.
· Prototyping Model: Focuses on creating a working prototype before full-scale development.
