What is risk in spiral model?
A risk is any adverse situation that might affect the successful completion of a software project.

Such risk resolutions are easier done by developing a prototype..
What is spiral model and its advantages and disadvantages?
The spiral model is a traditional agile model which contains 4 different stages:Planning, Risk Analysis, Engineering and Evaluation. … Software projects are constantly passing through phases in iterations,in other words spirals.
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).

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 are the spiral model deficiencies?
Disadvantages of Spiral Model: Process is complex. Too much dependable on Risk Analysis and requires highly specific expertise. Difficulty in time management. As the number of phases is unknown at the start of the project, so time estimation is very difficult.
