Evolutionary Process Models Flashcards
Q: What are evolutionary process models in software development?
A: Evolutionary process models are iterative allowing for the development of increasingly complete versions of software with each iteration.
Q: Name some common evolutionary process models.
A: Prototype Model Spiral Model Concurrent Model Unified Process Model.
Q: What is the Prototype Model in software development?
A: The Prototype Model is used when the full system requirements are unclear It involves building a prototype to gather feedback and refine the system iteratively.
Q: When is the Prototype Model most useful?
A: It is useful when requirements are unclear when a similar system doesn’t exist or when a quick delivery is needed for part of the system.
Q: What are the phases of the Prototype Model?
A: Communication Quick Design Prototype Construction User Evaluation Iteration based on feedback.
Q: What are some advantages of the Prototype Model?
A: Enhanced user involvement Early detection of issues Improved understanding of requirements Risk reduction Visual representation of the system.
Q: What are some disadvantages of the Prototype Model?
A: Time-consuming Increased complexity and scope creep Higher costs Potential for inefficient designs.
Q: What is the Spiral Model in software development?
A: The Spiral Model is an evolutionary risk-driven approach combining iterative prototyping with systematic planning often used for large high-risk projects.
Q: What are the phases of the Spiral Model?
A: Customer Communication Planning Risk Analysis Engineering Construction & Release Customer Evaluation.
Q: What are the advantages of the Spiral Model?
A: Strong focus on risk management Iterative flexibility Continuous customer feedback Early detection of errors.
Q: What are the disadvantages of the Spiral Model?
A: Complexity High costs Risk of project delays Requires expertise in risk assessment.
Q: What is the Concurrent Model?
A: The Concurrent Model allows different phases of development like analysis design coding testing to occur simultaneously rather than sequentially.
Q: What are the advantages of the Concurrent Model?
A: Flexibility Improved communication Early detection of issues Suited for large complex projects Reduced time to market.
Q: What are the disadvantages of the Concurrent Model?
A: Complexity in management Requires skilled teams Higher risk of miscommunication Difficult to track progress.
Q: What is the Unified Process (UP)?
A: The Unified Process is an iterative and incremental software development methodology focusing on architecture and risk-driven development.
Q: What are the phases of the Unified Process?
A: Inception Elaboration Construction Transition Production.
Q: What are the advantages of the Unified Process?
A: Focus on architecture Emphasizes documentation Strong risk management Adaptable and flexible Iterative and incremental development.
Q: What are the disadvantages of the Unified Process?
A: High cost Complexity Requires skilled personnel Heavy documentation Longer development time.
