Exploring SDLC Models and Requirements

What is the primary characteristic of the Waterfall Model?

• Linear and sequential development process.

• Iterative and flexible development process.

• Emphasis on continuous integration and delivery.

• Focus on rapid prototyping and feedback.

In Agile methodology, what is the purpose of a sprint?

• The purpose of a sprint is to deliver a potentially shippable product increment within a fixed time frame.

• To plan the entire project timeline in detail.

• To conduct a comprehensive market analysis.

• To gather all team members for a brainstorming session.

How does the Spiral Model differ from the Waterfall Model?

• The Spiral Model is only used for small projects, while the Waterfall Model is suitable for all project sizes.

• The Spiral Model focuses on documentation, whereas the Waterfall Model emphasizes user feedback.

• The Spiral Model is iterative and risk-focused, while the Waterfall Model is linear and sequential.

• The Spiral Model is a simple, one-time process, while the Waterfall Model is complex and iterative.

What are some common techniques for requirements gathering?

• Focus groups and brainstorming sessions

• Market analysis and competitive research

• Common techniques for requirements gathering include interviews, surveys, workshops, document analysis, and observation.

• Code reviews and testing phases

Define a use case in the context of software engineering.

• A use case is a diagram that represents system architecture.

• A use case is a programming language used for software development.

• A use case is a detailed description of a user's interaction with a system to achieve a specific goal.

• A use case is a type of software testing methodology.

What is the difference between functional and non-functional requirements?

• Functional requirements are always more important than non-functional requirements.

• Functional requirements describe the specific functions of a system, while non-functional requirements describe the quality attributes of those functions.

• Non-functional requirements only relate to system security.

• Functional requirements are about user interface design, while non-functional requirements are about performance.

What is a key advantage of using Agile over traditional models?

• Fixed project scope with no changes allowed.

• Increased flexibility and responsiveness to change.

• Reduced team collaboration and communication.

• Longer delivery times for project phases.

In the Waterfall Model, what phase follows the requirements analysis?

• Testing

• Deployment

• Implementation

• System Design

What is the role of a Product Owner in Agile methodology?

• The Product Owner defines the product vision, manages the backlog, prioritizes features, and ensures team alignment with stakeholder needs.

• The Product Owner conducts performance reviews for team members.

• The Product Owner manages the team's daily stand-up meetings.

• The Product Owner is responsible for coding the product features.

How does risk management play a role in the Spiral Model?

• Risk management is not considered in the Spiral Model.

• Risk management is integral to the Spiral Model as it facilitates early identification and mitigation of risks through iterative cycles.

• The Spiral Model eliminates the need for risk assessment entirely.

• Risk management is only applied at the end of the project in the Spiral Model.
