In contrast to the waterfall model, the spiral method enables the developer to make changes in the code or design even in the testing stage. In this software development methodology, developers start on a small scale then explores the risks involved in the project, makes a plan to handle the risks, and finally decides whether to take the next step of the project to do the next iteration of the spiral. This model clarifies the software development process in a linear sequential flow that means that any phase in the development process begins only if the earlier phase is completed. This approach constantly monitors the quality of software created and controls applied changes. DSDM is a Rapid Application Development (RAD) method that embraces incremental prototyping and incremental approach to address software development … It is a good practice that helps to ensure the product release and have a better version at the end of every iteration. The success of the projects done with this method is tied to high skill level and work experience. It is a waste of resources for projects with low-risk factors. This slows down the workflow. Let’s see how Agile, Lean, and Waterfall fare against each other when employed for mobile and web project development. Integration throughout the process of software development adds the confusion that causes more issues during the stages of testing. Software development is a complicated process from both perspectives and it is important to understand the pros and cons, common problems, and when to use an agile methodology. The strength of prototyping methodology is that it caters for all the lapses of the software engineering process. Introduction . Extreme programming is most suitable for creating software in an unstable environment. This kind of development methodologies are only concerned with the software development process, so it does not involve any technical aspect of, but only concern with proper planning for the software development. This leads to the improvement in the productivity of each of the team members, This kind of development model is suffered if the estimating project costs and time will not be accurate, It is good for small, fast moving projects but not suitable for large size projects, This methodology needs experienced team members only. Velvetech’s has always been a pacesetter in software production by applying the most effective development methodologies in different project types. Moreover, all these methodologies work well in certain projects depending upon the nature of the project. This method allows the identification of risks and the correction of errors at the initial stages of development. They visualize how it will run and prove its function to investors or clients. Different types of complexities in a project will demand different experts and level of experience in the method of choice. The commitment of the end-user is some worth proportional to the success of the method.

This method is complemented by the participation of active users in the development process. If any organization doesn’t have a person with the right business analyst then this method may not be useful for them, In this development model, great flexibility is given to developer which is surely great, but too much of it will quickly lead to a development team who lost focus on its original objectives thus, it hearts the flow of entire project development work, This methodology emphasizes on accurate documentation, It is proactively able to resolve the project risks that are associated with the clients evolving requirements for careful changes and request management, Very less need for integration as the process of integration goes on throughout the development process. Here are the most important of them: 1. Software development is not going away and how companies approach this service is key to their success. The business analyst on a lean project must have adequate set of skills and experience for proper requirements documentation. This model is more flexible – less costly to change scope and requirements. Changes in specifications and requirements will mean no accurate estimate deadlines for project completion.
