Designing A Waterfall Approach For Software Development Essay

Cost and resource needs are higher for traditional than Agile due to Waterfall’s sequential development phase of all requirements determined in the beginning, software design and finally implementation of master design. The need for all information up front takes substantial time to gather and the sequential design does not allow for project changes as the flow enters into the programming stage. With Agile, costs remain low because there exists an incremental and iterative approach to the project, meaning less time is used to collect all requirements up front, the

After having reviewed definitions and perspectives by three author groups, I’m inclined to conclude that waterfall methodology is essentially defined by its insistence upon the completion of product development steps in a sequential manner in order to accommodate a client’s need for a product or tool that will enable their business to be performed in a temporally defined effective (or desired) manner. By utility, for the sake of quickly delivering a product to the satisfaction of its client, a development team who employs the waterfall method may do so because of waterfall’s logical yet rigid structure. Its step-by-step nature promotes an easy to follow guide, though many of the tasks involved in the process of its development are anything but easy. Further, waterfall’s rigid nature seems to reinforce the notion of its logic, if but for the sake of timely product completion and client budget. Due to its methodological rigidity, however, products developed by way of waterfall may tend to be rigid in their own right.

Agile Development Methods (Agile) and the Waterfall Method (Waterfall) are two different styles of designing and managing the Soft Development Life-Cycle (SDLC)

how they should be applied, none have used project data to clearly conclude which one is

Focus is kept on the recurrence of condensed work cycles and also at the functional product yielded by the outcome, but in waterfall technique only once chance is been given to the development team to keep the project aspects right. But under the agile technique each and every feature of development including the design, requirements, is thoroughly checked under its lifecycle (Mahfuj et al, 2012). There is always some time to steer in another direction if a team stops at regular interval say after every two weeks and re-evaluates the project done.

Ultimately, while agile software engineering certainly represented a challenge to the well-established waterfall method, it didn't entirely throw away every element of the old guard (Cockburn, 2001). The new concept was actually based on the idea that individuals could better govern themselves, and could more effectively use their creativity within an overall framework if they were given some freedom to interact on a day-to-day level, facing problem-solving within the

The waterfall provides an orderly sequence of development phases, the first phase is gathering requirements for the development of a project. The next phase is analysis which includes activities such as problems identifying and analysis, and reduces the initial problems that may arise. After analysis follows design decision, this exactly derives how the system operates in terms of process, data, hardware, network, user interface, and other important factors in the system environment. Then comes implementation, this phase needs the most resource, cost, and even time-consuming phase when compared to other phases. In this actually system will built. Then testing will be performed on the implemented

Agile method is newer software development method in software industry. Until 2006, there are 17% of organizations are already using agile as their software devolvement method. Many and many organizations are getting interested and they are moving toward to adopt agile method nowadays. They believe agile methods are much more flexible and this method can bring significant benefits to their organizations, such as increasing quality, efficiency and customers’ satisfaction. However, there are some researchers found that agile method is not as good as expected. The studies suggest that there are

A traditional approach got a sequence of steps and cannot come back once done with sequence steps. Waterfall model is similar to this when we discuss traditional approach in software industry (Winston W. Royce, 1970). There is no need for all the projects to follow all steps in sequence. Some projects can skip some steps or can perform

The final myth postulated is that the Waterfall method is underappreciated as an industry best practice. The authors state that while a third of respondents cite it as the primary method of development, a slightly greater number of respondents

Software development is one of the highest demands in all over the world. We use software development techniques to solve the problems and to satisfy customers. Agile software development is a conceptual framework for software; it is also a group of software development methods based on iterative development. In 2001, agile software development was created by seventeen people with a desire to find alternative approaches to software development. The most important thing about agile methods are team work, conveying information to the team, face to face conversation, and satisfy the customer. There are various methodologies but I am going to describe the most popular ones.

The waterfall model consists of five phases such as requirements, Design, implementation, verification and maintenance. The method is a sequential design process where progress is seen as flowing downwards in a steadily manner, each development phase has its own distinct goals. The model is similar to water flowing down a cliff it can only flow in one way and cannot go back up it is the same with waterfall development ,after a development phase is completed it proceeds to the next development phase you cannot go back.

Matharu, Mishra, Singh, & Upadhyay (2015, p. 1) state that, “agile methods are characterized by shorter development cycles, higher customer interaction, incremental delivery, frequent redesign with accommodation of changes necessitated by dynamic user requirements.” The Agarwal et al. text explores three of the most popular agile methods, Scrum, Extreme Programming (EP), and Kanban. All of these agile methods follow The Agile Manifesto (Beck, et al., 2001).

TCS uses Software Development Life Cycle [SDLC] process consisting of a series of planned activities to develop or alter the software products. These processes are normally oriented toward either sequential software development processes, such as the Waterfall model, or Agile software development processes, such as the Scrum model.

Waterfall model is a software engineering process that has sequence of steps which are required for a product to be built or for the completion of a project successfully. This model starts with the requirements analysis phase and end with maintenance having several stages like design, implementation and verification. This model gives us a planned model for developing a product and deploying it in the market. This is also known as a sequential model.
