18 Questions
What is the main purpose of Software Development Methodologies?
To transform a user's requirements into a software product.
Define the Planning phase in the Software Development Life Cycle (SDLC).
Define project scope, goals, and objectives. Create a project plan and allocate resources.
What is the main focus of the Analysis phase in SDLC?
Gather and analyze user requirements. Define system specifications.
Explain the Implementation phase in software development.
Write code based on design specifications. Conduct unit testing.
What is the goal of the Testing phase in the SDLC?
Perform system testing to ensure the entire system works as intended. Identify and fix bugs.
Describe the Deployment phase in software development.
Release the software to users. Provide training and support.
What is the main characteristic of the Incremental Approach in software development?
Delivers the system in a series of increments
Explain the concept of risk-driven prototyping in the Spiral Model of software development.
Spiral Model is well-suited for large, complex projects where the risks & uncertainties are high.
How does the Spiral Model differ from the Waterfall Approach in terms of iteration?
Spiral Model allows for iterative development, whereas Waterfall Approach is a linear and sequential model.
What is the key advantage of using the Incremental Approach in software development?
Highest priority requirement is tackled first.
In the context of software development, what does SDLC stand for?
Software Development Life Cycle.
Why is the Spiral Model recommended for large, complex projects?
Spiral Model combines elements of both waterfall model and iterative development, making it suitable for high-risk projects.
What are the key characteristics of the Spiral model of the Software Development Life Cycle (SDLC)?
The key characteristics of the Spiral model are: 1) Allows for incremental releases of the product through iterations, 2) Uses a risk-driven and controlled prototyping approach, 3) Assesses prototyping results and determines risk areas to prototype further, 4) Explores the system at greater depth with each iteration, adding more detail.
How does the Spiral model differ from the Waterfall model in terms of software development approach?
The Spiral model takes a gradual and iterative approach, in contrast to the strict sequential flow of the Waterfall model. It allows for incremental releases and incorporates risk analysis and prototyping at each iteration.
When is the Spiral model particularly suitable for software development projects?
The Spiral model is appropriate for exploratory projects that are working in an unfamiliar domain or with unproven technical approaches.
What is the purpose of risk-driven prototyping in the Spiral model?
The purpose of risk-driven prototyping in the Spiral model is to identify and mitigate high-risk areas early in the development process through iterative prototyping.
How does the Incremental approach differ from the Spiral approach in software development?
The Incremental approach focuses on building and delivering the software in increments, while the Spiral approach incorporates risk analysis and prototyping at each iteration to gradually explore and refine the system.
Explain the key difference between the Agile/Scrum approach and the Waterfall approach in software development.
The Agile/Scrum approach is dynamic and iterative, with cross-functional teams working in short 'Sprints' to build and release software incrementally based on customer feedback. In contrast, the Waterfall approach follows a strict, sequential flow with all requirements defined upfront.
Learn about the Waterfall Approach in software development where activities are performed sequentially without iteration. This approach involves defining requirements, designing, building, and testing the full system at one time. Also known as a linear and sequential model.
