What are the steps in the spiral model of development?
The entire process of development is divided into four different stages which keep on repeating until the entire project is completed. These stages are Determining objectives, Evaluating risks, Developing the product and Planning the next phase. This entire process is represented in a spiral diagram and thus known as the spiral model.

Barry BoehmThe spiral model, proposed by Barry Boehm in 1986, is such an evolutionary process aimed at rapid development of more complete versions of the software or system by taking into account the technical and managerial risks associated with each evolutionary level.
Why is a spiral model more realistic?
A spiral model is a realistic approach to the development of large-scale software products because the software evolves as the process progresses. In addition, the developer and the client better understand and react to risks at each evolutionary level.

Is a waterfall model cyclic or linear?
It is a cyclic model. It works in a spiral shape, like a waterfall model, which is a linear one. It is a risk-driven model. They use prototyping. This model is very flexible as compared to the waterfall model. It needs documentation to maintain. Large projects are getting handled in a strategic way.

What is Spiral Model?
The spiral model was first introduced by Barry Boehm in 1986 in his paper – A Spiral Model of Software Development and Enhancement as an iterative and risk-driven model of software development.
When was the spiral model first used?
Spiral model was first introduced by Barry Boehm in 1986 and since then it has been one of the most preferred SDLC models for long-term and high-risk projects. This blog will discuss this prodigious and widely used SDL model in detail. Software Development Model plays a significant role in the success of any project.
What are the Drawbacks of the Spiral Model?
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.

One of the disadvantages of the spiral model is the time management as the number of phases are unknown.
What is the first stage of a repetitive cycle?
This is the initial stage where all the requirements are collected, objectives are defined, constraints are evaluated and different alternative solutions for the development are proposed. This is the first and foremost stage of each repetitive cycle.
When to use spiral model?
Another important thing to remember is that Spiral Model should be used in that kind of projects it was initially designed for . It can be a good option if you face a medium, or high-risk project and costs are highly important, a customer is unsure completely about his needs and requirements are complex, and significant changes are expected.
What is spiral model in software development?
In a few words, Spiral Model of software development can be characterized by repeatedly iterating a set of elemental development processes and eliminating risk, so it is actively being reduced.
How many stages are there in the spiral model?
As you can see, the Spiral Model consists of four main software development life cycle phases. The whole development process repeatedly passes through these stages. Each iteration is called Spiral.
Why is spiral model so expensive?
And here’s the reason. Spiral Model can be pretty costly to use and doesn’t work well for small projects. It’s a risk-driven model which means that the overall success of a project highly depends on the risks analysis phase. Risk analysis requires specific expertise on every iteration.
How do project estimates become realistic?
Project estimates in terms of schedule, costs become more and more realistic as the project moves forward, and loops in spiral get completed
Why is spiral model called meta model?
Spiral Model is called meta-model because it uses both Waterfall and Prototype models. But it’s highly important to understand that Spiral Model is not just a sequence of waterfall increments. Not at all.
Is spiral model flexible?
In fact, Spiral model is pretty flexible. You should remember that the diagram we’ve talked about earlier contains some oversimplifications. It may seem that everything on the project follows a single spiral sequence while it’s not. Real life project life cycle is more agile and flexible than this simple representation. There’s even a possibility to revisit the previous decision.

- It gives us space to get feedback directly from the customer.
- When a long term project is running, and commitment is not feasible due to changes made in economic priorities.
- We are using the spiral model because it is cost-effective. Development is getter faster as compared to the waterfall model. Also, features are getting added in a systematic way.
Conclusion
- It is concerned about risk management and awareness, which is a crucial part of any software development lifecycle. It gives the facility to involve the client in every iteration. This helps to overcome the drawbacks of the existing system. With this model, we can be more successful in getting customer satisfaction over time.
