What characteristic of spiral model distinguishes it from other development models?
The major distinguishing feature of the spiral model is that it creates a risk-driven approach to the software process rather than a primarily document-driven or code-driven process. It incorporates many of the strengths of other models and resolves many of their difficulties.
How many incremental models are different from spiral model?
Discussion Forum
| Que. | How is Incremental Model different from Spiral Model? |
|---|---|
| b. | Changing requirements can be accommodated in Incremental Model. |
| c. | Users can see the system early in Incremental Model. |
| d. | no difference between these two |
| Answer:Progress can be measured for Incremental Model. |
What is the major advantage 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. Flexibility in requirements.
Why is spiral model better than other models?
Risk Handling: The projects with many unknown risks that occur as the development proceeds, in that case, Spiral Model is the best development model to follow due to the risk analysis and risk handling at every phase. Good for large projects: It is recommended to use the Spiral Model in large and complex projects.
What are the different advantages and disadvantages of spiral model?
Spiral Model Advantages and Disadvantages
| Advantages | Disadvantages |
|---|---|
| Cost estimation becomes easy as the prototype building is done in small fragments | Spiral development works best for large projects only also demands risk assessment expertise |
How is Win Win spiral model different from spiral model?
How is WINWIN Spiral Model different from Spiral Model? Explanation: Except option “b” all other tasks/activities are present in Spiral Model as well. Spiral Model has user involvement in all its phases.
How many SDLC iterations are used in the spiral method?
four phases
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 is not true regarding spiral model?
– Risk analysis is involved in every cycle of development. – Only this model has the risk analysis phase. CORRECT ANSWER : Uses series of prototype for refining test execution plan.
Is iterative and incremental model same?
Iterative development is the process of repeating and improving the cycle/work style (iteration). The incremental model is where you build the entire solution in parts, but at the end of each phrase or section, you have nothing to review or feedback on.
What are the limitation 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.
Which feature of spiral model is most important?
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 copying up with risks by providing the scope to build a prototype at every phase of the software development.
