DevNet Associate (DEVASC) v1.0Software Development and DesignMedium
A software development team is adopting a methodology that emphasizes iterative development, frequent feedback, and adaptive planning. They want to deliver working software frequently, typically every few weeks, and be able to respond quickly to changing requirements. Which software development methodology aligns best with these principles?
- ABig Bang Model
- BWaterfall
- CV-Model
- DAgile
Show answer & explanationAnswer & explanation
Correct answer: D. Agile
Agile methodologies, such as Scrum or Kanban, are characterized by iterative development, frequent delivery of working software, continuous feedback, and adaptability to change. This contrasts with traditional linear approaches like Waterfall.
Why the other options are wrong
- A. The Big Bang Model is an unstructured approach, typically used for small projects with limited resources, not a systematic methodology for complex projects.
- B. Waterfall is a linear, sequential approach with distinct phases, not suited for frequent feedback or changing requirements.
- C. The V-Model is an extension of the Waterfall model, emphasizing verification and validation at each stage, still linear and less flexible.
Agile Methodology
Agile software development is a group of development methodologies based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams.
- Emphasizes individuals and interactions over processes and tools.
- Focuses on working software over comprehensive documentation.
- Prioritizes customer collaboration over contract negotiation.
- Values responding to change over following a plan.
- Common frameworks include Scrum and Kanban.
