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 also has these well-organized stages which helps in the classification and clarification on jobs needed to be done by the proponents. Limited on their time and resources, this gives the proponents a wider perspective or a different angle to view their tasks, thus creating the job’s focal point while minimizing or even eliminating minor tasks. One of the biggest cons of this model is its development time frame which complements the proponents’ problem of time. This also creates other problems like occurrence of uncertainties especially in the early stages of development. With all of such combined together, a slow start for the development is possible.
However, being output-oriented, the proponents still used the said model because of the greater chance of having a good system.
Planning Phase
The proponents conducted brainstorming activities on what kind of system they would like to develop and that they could develop. Having encountered a company that experiences the lack of proper technology in their processes, the proponents decided to create a system that will minimize resources while maximizing the number of finished tasks in the business process.
Analysis Phase
The proponents conducted an interview in the company of the study. This is done to further analyze the processes of Sales and Inventory Management from where the system is based upon.
Design Phase
Results from the analysis phase were the ones that were used in the designing and development of the system. Most data were from the interview done by the proponents which highlighted the problems of the company.
Implementation Phase
As the system gets nearer to its completion, the proponents presented the system on a regular basis for the company to know its status. This will also lead to the future implementation of the system to the company.
Maintenance Phase
The proponents received changes or updates in the company’s processes. Being near to its completion, these changes will only be possible in the maintenance phase of the system. These changes will be applied on the system’s update to avoid any other changes in the development of the current system.

The positive aspects of the Waterfall process include being simple to use. Each stage has entrance and exit criteria in order to move on to the next stage. This allows you to fully know when each stage is complete. According to Waterfall Model (2012), "The project requires the fulfillment of one phase, before proceeding to the next. Therefore if there is a fault in this software it will be detected during one of the initial phases and will be sealed off for correction.” (Advantages of the Waterfall Model). The waterfall model has been around for many years. Part of the success of this model is that it is easy to understand and people are comfortable using it. This is one reason it has survived as long as it has. The waterfall process is easy to manage since each phase has specific criteria and review process. This process allows for resource allocation which means people can be matched to tasks by analyzing their strengths. This process works well with small projects…

The project will be managed using a modified waterfall technique. In this approach, the initial two phases of the project will be fully defined and approved before starting to work on the subsequent phases. System documentation will begin and continue through the design, development, and installation of the system. The Project Management team will provide weekly status reports to the project sponsor so that real time corrections can be accomplished. Once the project sponsor has determined that each phase has met its purpose and provided the required approval, the next phase can begin.…

There are several Software Development Life Cycle methods that are availabel to utilize although, the Waterfall SDLC is the most desirable due to the simplicity and straight forward methods utilized and will be discussed in regards to topics in this paper. The benefits of this model type include departmentalization and manegerial control. A schedule can be set for each phase similarly to a how a factory system works from one step to the next in a proceeding manner until the product is complete. However, once in the testing phase it is difficult to revert back to make any additional changes. (SDLC Models., n.d.).…

Waterfall Model operates in a waterfall process tree. It has various phases such as requirement, design, implementation, verification, and maintenance that provide a successful execution to any system development. This model can be used in the development of frequent shopper program (Nicholls, 2005). The waterfall model's requirement phase will help Smith Systems Consulting to develop a program according to the need of Kudler Fine Foods. This model's other phases facilitate deep analysis of every aspect that provides appropriate development of the program. Each phase can be proceeded after the proper completion of the previous phase. This model facilitates Smith Systems Consultant’s advance knowledge about success or failure of the program, which helps to reduce failure risk. On the other hand, the waterfall model cannot facilitate the ability to update. In this model, information can be gathered after the process rather than during the process. This reduces flexibility to change pertaining to change in requirements. This aspect can make a faulty development as a result because it cannot be developed within the changing requirement of Kudler Fine Foods and relative environment. This may fail the whole program (Nicholls, 2005).…

The systems development life cycle (SDLC) is also known as the waterfall model. The systems development life cycle is a SDM (systems development methodology) that consists of seven phases. The seven phases are in a specific order that is completed phase by phase. The first phase is planning. The planning stage is where an outline is drawn up for preparations. During this phase a systems analyst, who may work for the company or be an outside consultant, will outline a proposed system, develop a budget, and create a detailed development schedule. To help make the decision, the company will perform four types of feasibility analyses: (1) technical, (2) economic, (3) operational, and (4) schedule. The second phase of the waterfall model is system analysis. The systems analysis phase follows the planning phase. In this phase a systems analyst would work with a company to understand the problem fully and detail the requirements of an information systems solution. This phase uses many tools and techniques, including requirements gathering, structured…

The practical example, validity and utility of the model:The models utility is in planned change, for example in a GE manufacturing plant we want to raise production at a particular level, we will conduct a systematic study to analyze what factors are helping towards achieving higher production level and what factors are pushing production down. After that, a planned effort is made to attain the new level and then stabilize on those levels. Then same process is repeated again. The validity of the method is established because in every new situation equilibrium develops. In the manufacturing field, once a certain level of production level is achieved it stabilizes at that level. Therefore efforts are made in the system for planned change that can be flexible and validated (Edgar H. Schein, 2002) .…
