A Study of WaterFall, a Software Development Model

According to en.wikipedia.org Waterfall “is a software development

model first proposed in 1970 by w.w. Royce, in which development is

seen as flowing steadily through the phase of requirements analysis,

design, implementation, testing, (validation), integration, and

maintenance”. Waterfall method is the first published model of a

software development process (1970). The basic principle is that the

different processes (Analysis, Design, Coding, and Testing) are done

sequentially. Output from one process is input to the next.

Waterfall method advantages like simple, easy to understand and work

with. Waterfall creates very detailed intermediate documentation

after each process. In general it is difficult to find situations

where the Waterfall method is especially suitable. For the method to

work the requirements have to be basically written in stone. It is

never recommendable for any Graphical User Interface work.

Iterative, Spiral and Agile

According to web definition iterative design is the integration of the

four steps in a traditional systems development process namely

analysis, design, construction and implementation, which are combined

into a single step that is repeated iteratively. Spiral design is a

systems development method (SDM) used in information technology (IT).

This model of development combines the features of the prototyping

model and the waterfall model and agile process is methods are

nonprofit organization. These methods were developed with the

understanding that software is difficult t...

Agile Development Method for my Organization IT

Agile represents a number of lightweight methodologies including DSDM,

Extreme Programming (XP) and Scrum. They follow principles from

established management science focusing on the value creation,

effective delivery of valuable software, offer delegation and

empowerment and encourage a hands-off management style.

For my organization I will introduce Scrum which is one the

lightweight and a good management tool.

    In the waterfall method, the steps have to be finished iterative, meaning the next step cannot be started until the previous step is completed. Once the current step is completed, then the next step can be started and so on. The customer does not get a working build during any of the steps and cannot make any changes in the scope at all. Once all steps are completed, the end result is given to the customer and then they can deploy and hope it does what they are needing it to do. If any of the steps need to be changed, then the whole process will need to be restarted from the beginning and the process began again. In agile methods, the process is more flexible. This method is flexible and can allow changes after each iteration. The goal of each iteration is to provide a working build so that the customer can give feedback on it and changes can be made, if needed, so that all requirements are met, or if requirements have changed since the initial build of the

  • Systems Development Life Cycle ( Sdlc )

    829 Words  | 2 Pages

    The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).

  • the affect of prototyping practices on design results

    1266 Words  | 3 Pages

    The article explains about the affect of prototyping practices on design results. Using Iterative practices in making designs can lead to better results. Instead of working on making a perfect design, Iterative practices helps designers to learn from their previous mistakes and give a better output. For example (cited in Bayles and Orland 2001), two groups were asked to make ceramics by a teacher. He accessed one group on quantity and the other group on quality. Surprisingly, the first group made many ceramics while learning from their mistakes while the quality group were just discussing about perfect design. This is a great example showing Iterative practice helps in making refinements to design process.

    The system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.

  • Overview of Agile Methodology

    1555 Words  | 4 Pages

    Agile development is chosen when the requirements are not clear. This is the reason that it is chosen for the projects where the rate of risk is high. Agile software development is best for the projects where the project can be divided in mini projects and these mini projects are completed by passing through the phase of design, coding and testing. The results of these iterations clear the requirements gradually. The feedback from the customers also clears the requirements. This is the reason that most of the companies use agile development methodology because of the fact that it has the capability to adapt to difficult situation and chase strict deadlines. Agile method is being used all over the software industry. Most of the developers are aware of the fact that Agile methodology is best for them.

    Scrum is basically a framework for agile development. Scrum is a process that is used most of the time during complex projects in software development. It is also a simple yet affective way to manage work. The strategy in Scrum is to divide members into a team and have them work together to achieve a common goal or project. Scrum provokes communication between the members of the teams. This communication is imperative to the success of the project.

    The Waterfall Model was first Process Model.. It is also called as a linear-sequential life cycle model. It is very simple to understand and use. In a waterfall model, each phase must be completed before the next phase begins. At the end of each phase, a review takes place to determine if the project is on the right path and whether to continue or discard the project and waterfall model phases do not overlap.

  • Advantages And Disadvantages Of Downfall Methodology In The Software Engineering System

    1848 Words  | 4 Pages

    What is the waterfall methodology? According to several software engineering sites, the waterfall methodology is also known as the linear-sequential life cycle model and also known as the traditional approach to software development. The waterfall model is as follows: Requirement of gathering and analysis, flowing down to, System design, then flowing down to Implementation, followed by Testing, and then Deployment of the system, and the final phase of Maintenance. The idea of the waterfall approach is that once a phase is completed, the process continues to move down the chain until all of the phases are completed and there is a product to deliver; the method is unidirectional. The waterfall approach is known for not allowing changes to be implemented passed the requirement gathering and analysis phase.
