Advantages And Disadvantages Of The Activities Of Software Developments

Using the waterfall approach the system developers will be able to focus on one piece of the system and move on each part separately. This will give the design team more time to focus on small sections of the new coding. Moving from one stage to the next means that each step has been checked thoroughly and is completed.

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.

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

Waterfall method is one of the traditional software developing method that has been implementing for decades. Usually, clients have requests, then software developers create an initial paln; after client approves the plan, developers follow through the plan; at the end, developers test and finish the task. Upon clients’ additional requests or tests, developers add up the extra features, but in most of the case, it would be too late or too hard to change. The entire process is not very communicative or translucent since clients and developers generally meet just once or twice throughout the project. In the article Why Making Software is so Difficult the author mentioned that software production is very

The waterfall technique has stages that it experiences. In the content, it says that, "no one developed the waterfall strategy" (Bowes, J.). It was acquired by big business programming engineers. There is a few advantages and disadvantages of the waterfall strategy. A few geniuses are "The advancement procedure has a tendency to be better recorded since this strategy places more prominent accentuation on documentation like necessities and outline docs. Numerous associations locate this consoling" (Bowes, J.). The waterfall procedure is one of the simpler ones to get it. A con of the waterfall strategy is "Frequently the general population we're building programming for (the customer) don't know precisely what they require in advance and don't have the foggiest idea about what's conceivable with the innovation accessible. Along these lines of working doesn't deal with this well" (Bowes, J.). This procedure doesn't have its own particular

The waterfall approach of software engineering makes use of use cases as a means of displaying and reporting data. Primarily the waterfall process is carried out using a Gantt chart. It requires each step to occur in a specific sequence where each stage has different

The Waterfall or Traditional model is a linear or Sequential approach to develop a Product. In this methodology, each phase of the product’s life cycle takes place in sequence of events like : Requirement gathering ,Design ,Developing ,System Testing ,User Acceptance Testing(UAT),Fixing the issues and delivering the finished product whereas Agile is an iterative and team based approach to develop a product. In agile methodology, Instead of developing the product with all the features at once we divide the project into the smaller segments called sprints and incorporate new features in each iterations or sprints. Instead of extensive planning and design up front, agile methodologies allow changing requirements over time by using the cross functional teams who work on successive iterations to develop a product. In this model, the goal of each iterative

The Waterfall method was originally developed in 1970 by Dr. W Royce to assist with the development of software. It has survived to this day through adaption and revisions enabling it to be one of the most widely used models (Charvat 2003). Its namesake originates from the analogy of a waterfall flowing downwards with the model following suit, cascading towards completion (Balaji and Murugaiyan 2012) this is known as a serial lifecycle. Each phase (starting in the top left corner) within the serial lifecycle is completed before moving on to the next phase until the end goal is reached (see Figure 1). This kind of method suits projects that have clearly defined stage goals, outcomes or solutions that are highlighted in the initial strategy of

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 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.

When assessing the reason “the field is young”, one may surmise that newer developers may adopt more modern methodologies. Agile modeling came about after more traditional practices. However, less experienced developers may lean toward a more known and proven theory like the waterfall approach which uses successive phases to be completed and finalized. The waterfall is rigid but more predictable and may be easier to manage for new project managers. Using different types of techniques may confuse a

Waterfall Model is the first software development process model proposed by Royce in 1970 which is a linear sequential software development life cycle (SDLC) model. It is a sequential process model which does not overlap. It means that until the one phase is not completed then next phase cannot start.

While the waterfall model has its flaws, it is important that an organization follows a model. With strict deadlines, tight budgets, and changing targets, a uniform process is required to meet the business needs. Ad hoc process cannot account for all the business constraints and timelines. The waterfall model provides a framework and clear track for software development. It is important to share best practices and evolve aspects of the waterfall method to meet today’s industry standards. Success can result from combining experience and knowledge, and best practices from the past and present and planning and adapting these for future expectations.

Q1: Take a suitable example to develop a software and implement the waterfall Model technique in it to develop the software ?

This includes the modification done on a system after it has been deployed to correct any system fault or make improvements on the system performance. This process involves a variety of activities such as the deletion of obsolete activities, error correction, and optimization among others. System maintenance process includes:
