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

which includes water fall‚ spiral and chaos models. Waterfall model is the earliest SDLC approach that was used for software development. In a waterfall model‚ each phase must be completed before the next phase can begin and there is no overlapping in the phases. The outcome of one phrase acts as the input for the next phrase sequentially. Following is a diagrammatic representation of different phases of waterfall model.

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.

The waterfall model is a sequential design process‚ often used in software development processes‚ in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception‚ Initiation‚ Analysis‚ Design‚Construction‚ Testing and Maintenance. The waterfall development model originates in the manufacturing and constructionindustries; highly structured physical environments in which after-the-fact changes are prohibitively costly‚ if not impossible. Since no formal software

Chapter 3 METHODOLOGY Research Design The developers will use the Sashimi (Modified) Waterfall Model‚ which serves as an efficient guide that will help the researchers in the development of the project. It is referred to as the “waterfall model with overlapping phases” or “the waterfall model with feedback”. The phases are the same as the pure waterfall model‚ but is done in discontinuous basis. This enables the phases to overlap and provide feedback between phases. The figure below shows

Experiment # 4a Title: Determination of the Hardness of Water from a Waterfall Aim: To determine the molarity of EDTA and to determine the hardness of water by measuring the concentrations of calcium and magnesium in a water sample by titration. Abstract: The aim of this experiment was to determine the molarity of a sample of EDTA and then to use this sample to determine the hardness of a sample of water. This was done using a titrimetric method. This was standardized using calcium chloride.

This Software Development includes all the phases from planning to acceptance. There are several models in Software Development Life Cycle‚ but understanding the difference between these models will make me easier to decide‚ which is the right model to be used for developing the project. There are three differences between Waterfall model
