Read the first 7 Software Development Lifecycle & Methodologies flashcards as text

  1. In the Spiral model of software development, what is the primary activity performed during the first quadrant?

    Answer: Identify objectives, alternatives, and constraints

    The first quadrant of the Spiral model focuses on determining objectives, identifying alternatives, and defining constraints for the current phase.

  2. Which Agile scaling framework uses a 'Program Increment' (PI) as its primary planning timebox?

    Answer: SAFe (Scaled Agile Framework)

    SAFe uses Program Increments, typically 8–12-week planning windows that align multiple Agile teams around a shared mission.

  3. What distinguishes a 'spike' story from a regular user story in Agile development?

    Answer: A spike is a time-boxed research task to reduce uncertainty before estimating

    A spike is a time-boxed activity whose goal is to gain knowledge or reduce risk, rather than to produce shippable functionality.

  4. In the V-Model (Verification and Validation model), which testing phase directly corresponds to requirements specification?

    Answer: Acceptance Testing

    Acceptance Testing validates the system against the original requirements specification, forming the top-right mirror of the V-Model's left-side requirements phase.

  5. Which software development practice involves developers integrating code into a shared repository multiple times per day with automated build and test verification?

    Answer: Continuous Integration

    Continuous Integration (CI) requires frequent code commits to a shared repository with automated builds and tests to detect integration errors early.

  6. A project team discovers that requirements are highly volatile and the customer wants frequent releases. Which SDLC model is MOST appropriate?

    Answer: Iterative and Incremental model

    Iterative and Incremental models accommodate changing requirements and allow frequent releases by breaking work into smaller, manageable iterations.

  7. In Kanban methodology, what is the purpose of setting a Work-in-Progress (WIP) limit?

    Answer: To prevent overloading the system and expose bottlenecks in the workflow

    WIP limits prevent teams from starting too many tasks at once, making bottlenecks visible and promoting a smoother flow of work.
