Spiral vs agile

The spiral model is a systems development lifecycle (SDLC) method used for risk management that combines the iterative development process model with elements of the Waterfall model. The spiral model is used by software engineers and is favored for large, expensive and complicated projects.

What is the difference between spiral and iterative model?

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.

What are the weaknesses of spiral model?

Disadvantages of Spiral Model:

It is not suitable for small projects as it is expensive.
It is much more complex than other SDLC models.
Too much dependable on Risk Analysis and requires highly specific expertise.
Difficulty in time management. ...
Spiral may go on indefinitely.
End of the project may not be known early.

What is the disadvantage of spiral model?

Disadvantages of Spiral model: Can be a costly model to use. Risk analysis requires highly specific expertise. Project's success is highly dependent on the risk analysis phase. Doesn't work well for smaller projects.

What are the 4 phases of the spiral development process?

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).

What are the 4 principles of agile?
