Waterfall (M. C. Escher) Waterfall is a lithograph print by the Dutch artist M.C. Escher which was first printed in October‚ 1961. It shows an apparent paradox where water from the base of a waterfall appears to run downhill before reaching the top of the waterfall. Waterfall‚ Original lithograph print by M.C. Escher A stylised version of the channel in Waterfall with ambiguous 3-dimensional detail added While most two-dimensional artists use relative proportions to create an illusion

1. Discuss in details the advantages and disadvantages of Waterfall model. When to use it? When not to use it? How is it related to the Scope? (25 points) Answer – As the name suggests it is a simple process which is one way and does not have flexibility to revise the process phase already completed same as water once fall cannot jump back to its initial position. In this model one phase is completed and reviewed fully to enter the next phase. In this model phase do not overlap. Advantages

Waterfall vs Agile Development A Director of IT Programs at a large Aerospace Defense contracting company has been asked to develop a financial system that allows the Program Managers for the company to do their Earned Value Analysis. The development of this system will allow the company to manage their programs more efficiently and maintain the Government certification of their Earned Value systems. If the company loses their certification the government can withhold 5% of their profits on

Overview of Language Teaching Methodology The word "methodology" is itself often misinterpreted or ill-understood. It is usually given lip-service as an explanation for the way a given teacher goes about his/her teaching‚ a sort of umbrella-term to describe the job of teaching another language. Most often‚ methodology is understood to mean methods in a general sense‚ and in some cases it is even equated to specific teaching techniques. It does (or should) in fact mean and involve much more than

This chapter describes the various options to be employed by the researcher in answering the research questions. The basis of methods used to collect data of the system problem is presented. It includes specific methods which were used to achieve the objectives of the project and a justification

I will be explaining a little more in-depth of how the Systems Development Life Cycle (SDLC) operates. The SDLC process is a Systems Development Methodology (SDM) “which is basically the process most businesses go through to develop and maintain an Information System.” (Ross A. Malaga‚ (2005) Information Systems Technology‚ Published by Prentice Hall. Page 285. Copyright 2005 Pearson Education) The SDLC contains seven major phases; I am going to start on the first which is‚ Planning. Planning is

1 Modified Waterfall Model A Modified Waterfall Model (See Figure 7) from the System Development Life Cycle was used by the proponents in this study. This model involves validation or verification between the phases of the traditional Waterfall Model. This combination enables the early corrections of any deviations in the processes. This model also supports proper development documentation. For that reason‚ the proponents became one-step closer in using the Modified Waterfall Model. This model

Chapter 3 METHODOLOGY Research Design In developing the system‚ the developers will use the waterfall model as the software development methodology or also known as SDM. The waterfall model is often used in software development processes it is a sequential software development model in which development is seen as flowing steadily downwards through several phases. It is often divided into phases or stages to reduce the implementation complexity. The phases of the model are analysis‚ design‚ implementation

The agile and waterfall method are two of the most common methods when it comes to how to approach software development. Every company has a preference when it comes to the method they use and while there are some similarities between the two methods‚ there are also quite a few differences. In Subhajit Datta’s article‚ he mentions that the waterfall method identified core elements within the software development process that have since been adapted by other methods‚ including the agile method.
