Waterfall Model Is Based On Sequential Process - 1104 Words

Waterfall model is based on sequential process that is used in software development process. It takes place in steps. It is called as waterfall because it moves step by step in downward direction. As seen in manufacturing and construction site, each process is well structured and carried out step by step, in software development Waterfall model carries out all phases in sequential manner. All the phases like Conception, Initiation, Analysis, Design, Construction, Testing, Implementation and Maintenance are carried out in a sequential manner, step wise. It is stated that the first formal description of Waterfall model was made in 1970 in the article written by Winston W. Royce. Though the first use of waterfall model was made in 1976 in the article written by Bell and Thayer. 2.0 Spiral Model 2.1 Introduction Overview [2] Spiral model is another alternative process that is used in software development cycle. It is more focused on risk analysis. It is based on unique risk pattern that is adopted by the software. It can adopt any of the software development process such as incremental, evolutionary prototype and waterfall model. This method was introduced in 1986 in paper written by Barry Boehm. This model has four phases Planning, Risk Analysis, Engineering and Evolution. At each progress the software project has to be passed through all these four phases. The baseline spiral is reference for each other subsequent spirals. The baseline spiral starts with the planningShow MoreRelatedA Detailed Look Into The System Implementation1640 Words   |  7 Pagesmanagement used to show activities (tasks or events) displayed against time. METHODOLOGY The framework within which the process of developing an information system is planned, structured and controlled. PROTOTYPE A model by which a system is developed. MODEL A visual design or representation of a system. WATERFALL A linear software methodology implemented in sequential phases while emphasizing on documented plans, schedules and targets set on each phase.

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. The V-Model is an SDLC model that is also based on the Waterfall Model. Both the Waterfall and the V-Method are sequential methods, which means every phase must be completed before moving onto the next step. The main difference between the Waterfall and the V-Model is that the V-Model has a testingRead MoreDisadvantage Of Waterfall Model907 Words   |  4 PagesWaterfall Model benefit, disadvantage and critique 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. †¢ Requirement Analysis: often know as Software Requirements Specification (SRS). In this phase, all requirements of the software product are collectedRead MoreThe System Development Life Cycle1377 Words   |  6 Pagesgroup of people that work in the organization, as system development get bigger in an organization so also there are needs to systemize the process of system development and come up with a set of steps that are required for any system development.

In today’s businesses, systems development is a process of examining a business situation to analyze better procedures and methods to stay competitive. System development life cycle (SDLC) methodologies are promoted as means of improving the management and control of the software development process, structuring and simplifyingRead MoreImplementing Developing An Information System1347 Words   |  6 Pagesthe process of developing an information system.

Ans: The waterfall model shows a process, where developers are to follow these phases in order: 1. Requirements specification  (Requirements analysis) 2. Software Design 3. Integration 4. Testing  (or  Validation) 5. Deployment  (or  Installation) 6. Maintenance In a strict Waterfall model, after each phase is finished, it proceeds to the next one.

Laplante and Colin J. Neill of Penn State University explores the rumors of the demise of the waterfall model. The Waterfall process model progresses software products linearly from conception, through requi rements, design, code, and test (Neill, 2004). The Waterfall method was developed in 1970 by Winston Royce when computer systems were monolithic, number-crunching entities with rudimentary front ends and users’ needs were filtered through the partisan minds of the computer
