Advantages And Disadvantages Of The Waterfall Method

The biggest advantage that Scrum has over Waterfall is the ability for the customer to see and use the software early. Many times customers do not really understand what they want until they are actually using the software so having the software available early allows them to provide feedback immediately. If there are changes to made they can be added to the next sprint and adjusted quickly without much cost in

The rigid methods employed by the Waterfall approach makes it easy to manage because the team cannot move onto the next stage if all of 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.

This is also a process that is able to analyze every step stage of the project. This is beneficial because it helps businesses to know that they are staying on budget and whether the project will be completed on time.

Agile development and project management has its roots in the Information Technology world. A large portion of the information that follows in the next two chapters refers to IT related development and projects. That being said, Agile is not limited to IT and in fact the model is expanding well beyond strictly IT.

Provides the client with cost certainty as long as the clients requirements have been properly interpreted by the contractor.

Finding out what will permit an organization to work optimally is the driving impetus behind almost any business or organizational theory. The Waterfall Method appears, at first glance, to be a lot like the Roman Civil Code: anticipate as many contingencies as possible, and then proceed to delineate how they will all be tackled. The problem, as the literature seems to note, is that there will always be things or exigencies that cannot be anticipated – which is why agile

Looking at each methodology from a different perspective, the management perspective, unveils additional benefits and setbacks. The rigidity of the Waterfall method for software development can be cumbersome when dealing with changing expectations, but it makes it easier for management to manage the project’s progression. Having clear goals makes it easy for managers to track the development process. It is more difficult to track a project where requirements are constantly evolving. Most of the projects (not involving software development) in our department are tracked through their process. As goals are achieved, completion nears 100%.

Agile is a member of software development mode. Actually It is not a technique. I think not only it is a methodology, but also it is a process of development software. It will show and guide us to finish the development step by step according to the project required. However this kind of development mode is driven by human. The human will control the direction of the project.

Waterfall development has distinct goals for each phase of development. This case because, due to difficulty of returning to an earlier phase. The model shown here is one of several more or less equivalent alternatives.

Due to its characteristics, the Waterfall method has some really good advantages towards it. First of it, the client knows what to expect. After all the requirements gathering and analysis a well estimated project is presented, with a good idea of the size, cost, and timeline for the project. More than this, the client will have a definite idea of what their program will do in the end. Secondly, its meticulous record keeping allows the ability to improve the existing program in the future, and because of waterfall’s strong documentation it allows for minimal project impact when facing an employee turnover. These two main points, predictability and well-documented projects are the Waterfall flagship in an industry that pursue the best cost

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

In conclusion, agile software development is a very exciting and useful approach, although some project suit agile more than others. The collaboration and visibility can provide a much better and rewarding experience for the team to develop software products. Over the last years, many companies dramatically improved their performances

Since the waterfall model is very straightforward and understandable and it follows a step-by-step procedure, ideas are presented in a specific manner. The users of the model focus on only merely idea at a time and follow the waterfall model’s phases and will carry on to the next set of ideas for specified phases. As said in the other component of the research, the users of this model cannot proceed unless the stage in focus is finished.

However, there are lots of weaknesses for Waterfall during development. The Waterfall model is not flexible and it’s too slow and costly because of the process cannot be changed and need to ensure each step finish before move to next one.
