    Question

    Which of the following Software Development Life Cycle

    (SDLC) models is best suited for projects where the requirements are unclear or evolving rapidly?
    A Waterfall Model Correct Answer Incorrect Answer
    B Agile Model Correct Answer Incorrect Answer
    C V-Model Correct Answer Incorrect Answer
    D Spiral Model Correct Answer Incorrect Answer
    E Incremental Model Correct Answer Incorrect Answer

    Solution

    The Agile Model is an iterative and incremental SDLC approach, making it highly effective for projects with rapidly changing or unclear requirements. Agile emphasizes collaboration, customer feedback, and adaptability. Instead of defining all requirements at the start, Agile breaks the project into smaller cycles called iterations or sprints, each delivering a working product increment. Agile’s flexibility allows teams to incorporate changes at any stage, ensuring the end product aligns with user needs. Agile is particularly favored in dynamic industries like software development, where user expectations and market trends evolve quickly. Why Other Options Are Incorrect: 1. Waterfall Model: Requires clear requirements upfront; changes later in the cycle are costly and challenging. 2. V-Model: A linear approach where testing is planned alongside development; unsuitable for evolving requirements. 3. Spiral Model: Suited for high-risk projects; involves extensive risk assessment and not ideal for unclear requirements. 4. Incremental Model: Delivers parts of the system incrementally but lacks the agility to accommodate frequent changes. Agile’s emphasis on adaptability, continuous improvement, and stakeholder collaboration makes it the preferred choice for evolving projects.
