Spiral model

There are number of reasons because of which ongoing project may stop. In order to overcome the hurdles in the future it is essential to make a brief study of the possibilities of the future problems and likewise steps must be taken for avoiding such problems. This will help the project to be carried on nonstop without any future hurdles and it also help to save time and money. Spiral model, is one such model which is useful in such situations where the future planning is essentials to eliminate the possible risks in the future. It helps to guide the risks that the project may face in the mere future and what steps should be taken t overcome such risks. The Spiral model has a unique process design which helps to eliminate the risks in the future.

The spiral model is a four stage model. The four stage are nothing but part of a circular path which are critical in providing the guidelines for the future. Each stage of the spiral model is represented by one quadrant of the Cartesian design. The cost incurred is represented by the radius of the model. The four activities or stages involved in the spiral model are as follows:

Planning: It helps to understand the underlining concept of the project. We get acquainted with the objectives, alternatives and the constraints of the project or the product which is under process. It is essential that a lot of time must be invested for planning as it is the base of the spiral model, even if the slightest negligence can adversely affect the process.

Risk analysis: In this stage all the potential risks involved in the future are analyzed carefully. This stage is most vital stage of the model as the main process actually starts from Risk analysis. In this process the potential risk areas are taken into consideration and solutions are drawn to overcome the risks. Also, in Risk analysis alternative options are evaluated which becomes easier to overcome the future risks.

Engineering: Once the risk analysis is done the next step is the actual development and the verification process. This is done by using either a prototyping approach or the simulation.

Custer evaluation: The customer evaluates the model and checks it in and out. If there are any modifications to be made the customers give feed back to the developers.

The spiral model is one of the most realistic approaches which are very essential for the development of the large systems. By spiral model the developers can also apply the prototyping and the customer’s evolutions approach to make the project more unique and successful.
