## When would you use a RAD model?

RAD should be used only when a system can be modularized to be delivered in an incremental manner.

It should be used if there is a high availability of designers for Modelling.

It should be used only if the budget permits use of automated code generating tools..

## For which types of development projects is spiral model suitable?

The spiral model is a combination of sequential and prototype models. This model is best used for large projects which involve continuous enhancements. There are specific activities that are done in one iteration (spiral) where the output is a small prototype of the large software.

## What spiral means?

The Spiral is a sacred symbol that represents the journey and change of life as it unfolds; taking a labyrinth-like passage that leads to Source. The spiral symbol can represent the consciousness of nature beginning from its center expanding outwardly.

## What is spiral model and its advantages and disadvantages?

These are following advantages and disadvantages of using Spiral Model. Advantages of Spiral Model: Software is produced early in the software life cycle. Risk handling is one of important advantages of the Spiral model, it is best development model to follow due to the risk analysis and risk handling at every phase.

## What are the advantages and disadvantages of V model?

Disadvantages of V-model: Very rigid and least flexible. Software is developed during the implementation phase, so no early prototypes of the software are produced. If any changes happen in midway, then the test documents along with requirement documents has to be updated.

## What is a square root spiral?

In geometry, the spiral of Theodorus (also called square root spiral, Einstein spiral or Pythagorean spiral) is a spiral composed of right triangles, placed edge-to-edge. It was named after Theodorus of Cyrene.

## Which is the most important feature of spiral model *?

The most important feature of the spiral model is handling these unknown risks after the project has started. Such risk resolutions are easier done by developing a prototype. The spiral model supports coping up with risks by providing the scope to build a prototype at every phase of the software development.

## What is risk in spiral model?

The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model). … Risk Analysis: In the risk analysis phase, a process is undertaken to identify risk and alternate solutions.

## What is Winwin spiral model?

The spiral model suggests a framework activity that addresses customer communication. The objective of this activity is to elicit project requirements from the customer. … Boehm’s WINWIN spiral model defines a set of negotiation activities at the beginning of each pass around the spiral.

## Which model is most popular for student’s small projects?

2) Which model is popular for students small projects ?Waterfall Model.Spiral Model.Quick and Fix model.Prototyping Model.

## Why do we use spiral model?

Spiral Model Application The Spiral Model is widely used in the software industry as it is in sync with the natural development process of any product, i.e. learning with maturity which involves minimum risk for the customer as well as the development firms.

## How does the spiral model work?

Definition: The spiral model is similar to the incremental development for a system, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Design, Construct and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model).

## Is spiral model agile?

The main principle of the Spiral model is risk handling. The Agile model focuses on the delivery of an increment to the customer after each Time-box, so customer interaction is more frequent. Spiral model mainly deals with various kinds of unanticipated risks but customer interaction is less.

## What is risk driven model?

The Risk-Driven Model guides developers to do just enough architecture by identifying their project’s most pressing risks and applying only architecture and design techniques that mitigate them. The key element of the Risk- Driven Model is the promotion of risk to prominence.

## What is the difference between spiral and iterative model?

Answer Added!!! A iterative model is a way to describe a SDLC as a sequence of consecutive steps. A spiral model is a way to implement a iterative model, where each iteration follows a waterfall-like model. With each iteration, the product is updated, more features are added etc.

## How spiral model is different from other models?

Both the models, Waterfall model and Spiral model are used in software development. Waterfall model is also known as classical or linear model because it follows sequential stages while the spiral model does not follow the sequential stages it follows the evolutionary way.

## What is a spiral test?

Spiral testing is a risk based testing, where testers will take risk due many factors at the same time they will equipped with solutions for that risks. … Testing as an integrated function prevents development from proceeding without testing.
