Types of Software Development Approaches: Waterfall Model

To transform a user's requirements into a software product.

Define project scope, goals, and objectives. Create a project plan and allocate resources.

Gather and analyze user requirements. Define system specifications.

<p>Spiral Model combines elements of both waterfall model and iterative development, making it suitable for high-risk projects.</p> Signup and view all the answers

<p>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.</p> Signup and view all the answers

<p>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.</p> Signup and view all the answers

<p>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.</p> Signup and view all the answers

<p>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.</p> Signup and view all the answers

<p>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.</p> Signup and view all the answers
