The Original Waterfall Model Has A Foundation That Is Supported By Two Distinct Characteristics Essay

The project will be managed using a modified waterfall technique. In this approach, the initial two phases of the

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.

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

It has been observed that in software development, change is unavoidable and must be accommodated for in the life cycle. A number of alternative process models have been introduced in order to attempt to fix the issues in the Waterfall model. An early modification to the standard Waterfall method introduced prototyping as a feedback and discovery mechanism to identify misunderstandings and omissions early on in the process (Neill, 2004). Other process models attempted to further get rid of the risks of misunderstandings by breaking down projects

The traditional development method requires the definition and documentation of a stable set of requirements at the beginning of the project. It was inherited by other projects mainly related to construction which focused on the completion of one phase of production before moving on to the next phase, for example, laying the foundations of a building first and then proceeding with the further stages (Bowes 2014). Similarly, in Waterfall, the requirement gathering and designing work is done upfront before any coding takes place. The basic notion behind the traditional development approaches is that the projects are comparatively less complex, linear and predictable with clearly defined system boundaries which makes it simple to plan and follow without having any room for changes (Spundak 2014). Moreover, traditional development method depicts the requirements document as he key piece of documentation. The gathering of all the requirements, getting a sign off from the customer and then starting with the development of the project gives the project a limit of

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.

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

Also in addition to my studies about Agile, I have made efforts to compare the same with another heavy weight methodology called Waterfall. Comparison include the strength and weakness of the two opposing methodologies and the outcome of a controlled empirical study conducted at Carnegie Mellon University in Silicon Valley by Feng Ji and Todd Sedano.

In the world of business and project management, there are certain ways in which projects get completed. Many of these ways are known as models or methodologies. Most of these models stem from the SDLC, or the Software Development Life Cycle (Tutorials Point). One of these alternative models is known as the V-Model or V-Method.

This means that as each of the individual eight stages (conception, initiation, analysis, design, construction, testing, implementation, and maintenance) are accomplished, the designers move on to the next step. Being that this is sequential processes, when a step has ended, creators cannot go back to an earlier step, that is, not short of scrapping the entire project and starting from the beginning. There’s no room for modification or inaccuracy, so a project outcome and a wide-ranging plan must be fixed in the creation and then followed cautiously. The waterfall methodology stresses thorough record keeping. Having such records will provide the project managers the capability to improve upon the existing program in the future. The client knows what to expect when the waterfall methodology is used. . They’ll have knowledge of the scope, price, and timeline for the project. They will also have a definite indication of what their program will do in the end

Each increment includes a planning phase where high level requirements are defined. These requirements are bundled into delivery cycles and at the end of each delivery cycle a working functionality is delivered to the customer. Iterative life cycles are scalable and can be used for large or small projects. They are also useful when projects have predefined schedule constraints. Other types of life cycles are sequential life cycles and prototyping life cycles. Sequential life cycles include models such as the Pure Waterfall Method, differ from agile because the product is not delivered until the end of the project. The waterfall method however, implements phases such as the agile method but, these phases produce documentation not working deliverables to the customer. The waterfall method works well for projects with customers that know what they want and are fully committed to the project. Prototype life cycle models are particularly unique. A prototype life cycle model, such as the rapid prototyping model, is commonly utilized as a visual tool than an entire standalone process. Rapid prototyping is designed to model a piece of software and product with limited functionality. The rapid prototyping model is usually incorporated into the waterfall method during the concept definition phase to provide a visual aid to the customers, since no working

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.

A software development methodology is a structure imposed on the development of a software product. It is used to structure, plan and control the process of developing an information system including procedures, techniques, tools and documentation aids. A wide variety of methodologies have evolved over the years, majority aggress that all these methodologies are distinguished into two categories – Heavyweight or Lightweight. Heavyweight methodologies are also known as traditional methodologies which approach system development with standard, well-defined processes such as Waterfall, Spiral and Unified Process. Lightweight methodologies

We believe that the Novopay system adapted the Waterfall methodology because basically their system was built in a plain and simple way. We also believe they used this methodology because they wanted the payroll system to be easier to manage, and desired each step or phase
