Mell Is spiral model A meta model?
The spiral model is called a meta model since it encompasses all other life cycle models. Risk handling is inherently built into this model. The spiral model is suitable for development of technically challenging software products that are prone to several kinds of risks.
Why is spiral model reffered as meta model?
“Spiral model is called as Meta Model” because it comprises of other Software Development Life Cycles. For example, a single loop spiral actually represents the Iterative Waterfall Model. The Spiral Model uses a Prototype Model to build a prototype before the actual product development starts.
Which software life cycle model can be considered as the meta model?
Answer: “Spiral model” is called as “meta model” because it comprises of other software development life cycles. Spiral model is a “risk driven process” model and hence risk handling is by default inherited in it.
What model is known as meta model and why?
The Spiral model is called a Meta-Model because it subsumes all the other SDLC models. For example, a single loop spiral actually represents the Iterative Waterfall Model. The spiral model incorporates the stepwise approach of the Classical Waterfall Model.
What is the major drawback of a 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. Process is complex. Too much dependable on Risk Analysis and requires highly specific expertise.
Which is an example of a spiral model?
The Spiral model can be viewed as a Meta-model since it subsumes all the initial models. For example, a single loop spiral represents the waterfall model. The Spiral model uses a prototyping approach by first building a prototype before embarking on the actual product development effort.
How does the spiral model support software development?
The spiral model supports coping up with risks by providing the scope to build a prototype at every phase of the software development. Prototyping Model also support risk handling, but the risks must be identified completely before the start of the development work of the project.
Is the spiral model expensive for risk analysis?
Expensive The spiral model can be quite expensive as it requires a high level of expertise for risk analysis. Even the projects take a huge amount of time to develop that can spike the overall expenses. Quite Complex The spiral model is comparatively more complex than other SDLC models.
How does a model conform to its metamodel?
A model conforms to its metamodel in the way that a computer program conforms to the grammar of the programming language in which it is written. Various types of metamodels include polynomial equations, neural network, Kriging, etc. “Metamodeling” is the construction of a collection of “concepts” (things, terms,…
