Topic: Waterfall model


  
 Waterfall model - Wikipedia, the free encyclopedia
The waterfall model is a software development model (a process for the creation of software) in which development is seen as flowing steadily downwards (like a waterfall) through the phases of requirements analysis, design, implementation, testing (validation), integration, and maintenance.
It is perhaps for this reason that the waterfall model is used as a beginning example of a development model in many software engineering texts and courses.
Rather than what the waterfall adherent sees as "chaos" the waterfall model provides a structured approach; the model itself progresses linearly through discrete, easily understandable and explainable "phases" and is thus easy to understand; it also provides easily markable "milestones" in the development process.

 waterfall model in TutorGig Encyclopedia
The 'waterfall model' is a software development model describing the naive approach to software development in which development is seen as flowing steadily through the phases of requirements analysis, design, implementation, testing (validation), integration, and maintenance.
Despite the fact that the waterfall model has never been advocated by software development methodologists it is seen to emerge naturally in companies lacking expertise and experience in software development methodologies.
The lifecycle can take so long that the original requirements may no longer be valid by the time the system is implemented.

 The Waterfall Model Explained
Waterfall approach was first Process Model to be introduced and followed widely in Software Engineering to ensure success of the project.
One such approach/process used in Software Development is "The Waterfall Model".
In "The Waterfall" approach, the whole process of software development is divided into separate process phases.

 Comparison of Software Development Methodologies - January 1995
Many software development methodologies have evolved from attempts to optimize the waterfall model for software.
Since the approach to developing complex hardware systems was well understood, it provided a model for developing software.
For example, software prototyping helps provide the complete understanding of the requirements that is typical of hardware production--which understanding is critical to the waterfall model.

 SENG 611
In this model, the software is developed in incremental stages where each stage adds additional functionality to the software.
This model allows developer to add functionality into software earlier than either the waterfall or v-shaped model and functionality can also be developed according to the level of importance.
This model allows developers to create a quick implementation of the software (prototype) before or during the requirements phase.

 Software Life Cycles Summary
In the model, development of the software are in stages where each stage is comprise of design, code and unit test, integration test and delivery.
From my experience, the Waterfall model seems to be driven by business oriented authorities instead of in coherence with the software development group.
The Spiral model is good to adapt as most software life cycles do not take into account the many risks of software development.

 How Do We Build A Correct System - Software Development Process, Methodologies, Methods & Techniques.
The waterfall model is a linear progression of project activities, where an input is received by an activity, processed, and the output is delivered to the next sequential activity as the input to that activity.
A Methodology is composed of a Software Development Model used in conjunction with one or more Software Development Techniques.
The recognition of the software crisis led to the birth of software engineering which, in turn, led to structured models for describing the software life cycle in order to make the process predictable and controllable — resulting in the production of a correct software system.

 Waterfall Model
Waterfalls work for simple projects (prototypes for example), and in some cases it's just the simplest thing that could possibly work, even with minor misapplication (you know, WorseIsBetter and all that).
The idea is that there is a model where requirements, specification, analysis, development, test, what have you proceed in parallel.
I think you can use Waterfall essence generatively to tailor a process for developing a particular piece of software.

 System Development Life Cycle
The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application.
The image below is the classic Waterfall model methodology, which is the first SDLC method and it describes the various phases involved in development.
Some methods work better for specific types of projects, but in the final analysis, the most important factor for the success of a project may be how closely particular plan was followed.

 Lux Resources Web Accessibility
There are a number of ways Lux modifies the waterfall approach to give it nearly all of the advantages of the ERA approach without the disadvantages.
However, we believe that, as an overarching methodology, ERA is a temptation that beckons to people who love to have boisterous meetings and code a lot of throw-away software rather than engage in difficult analysis and build solid, reliable, scalable, well-tested systems.
This includes elements of approaches such as RAD ("Rapid Application Development") and Extreme Programming that are traditionally considered to be diametrically opposed to the waterfall model.

Anyone who has worked on a so-called waterfall model project where big chunks have late requirements will know what I mean.
You fix the requirements at each stage and move on 'knowing' that you are working on a fixed baseline.
And, you begin each iteration (design the next component) from the basis of how this next component will fit in with what you have already completed.

 The Waterfall Lifecycle Model and its Derivatives
Not that all software developers, or project students!, are rational and careful; and it is easy for the inexperienced to misjudge the levels of complexity, novelty or risk.
On the other hand, it is unlikely that a viable dissertation project could be completed without some form of planning and phasing of tasks.
Thus there was the means to design the software on the basis of abstract-data-types.

The waterfall model that was developed in the 1970s which is commonly used for software engineering.
In terms of requirement engineering, this model is optimal for larger projects, where several people are involved with a variety of task.
Of course, a small project could benefit from this but the cost might be too high, compared to the possible benefit of the project and because of the complexity and the need of considerable risk assessment.

It is attributed with providing the theoretical basis for other Process Models, because it most closely resembles a "generic" model for software development.
