Case Study: The Waterfall Model

1426 Words6 Pages

MATHEMATICAL MODELING SQQM 3024 (Group A) Individual Project Lecturer: Dr. Woon Siew Fang Prepared by: Tan Jit Seng (221042) Objective of the study. The objective of the study is to optimize the recourse needed to run all the specific scale projects by using the Waterfall Model. In order to find the number of employees needed, we will run the model with a simulation tool which is Symphony.NET. The proposed model is to overcome the weaknesses and problems due to the use of model of Software development life cycle (SDLC). Before the simulation process is started, the project manager needs to determine the five phase in the Waterfall Model. Those five phases are business analysis, design, implementation, testing, and maintenance. …show more content…

The proposed model has given the project manager a better and convenience in the recruitment process. There have five phases in the Waterfall model, which are business analysis, design, implementation, testing, and maintenance. In this proposed project, the project manager can determine the total number of resources that needed in each phase in order to run the specific scale projects that meet the proposed objective. Because of the complexity and time consuming to find out the number of workers needed to run the specific scale project, thus in this article, the “Simphony.NET” is applied. Model development. In this case, the model development contains 7 steps namely problem identification, system observation, mathematical formulation, verifies and model prediction, alternative selection, result and conclusion, and also the recommendations (Winson 2004). This structure can help the modeller to design and solve an organization’s problem. Step 1: Problem Formulation The project manager faced a difficulty to determine the balance between the budget, time and the effective process to run the …show more content…

In addition, in this simulation tool, the project is made by link the modelling elements to each other by logical relations. Essentially, the proposed model consists of a set of resource, queue, task, probability branch, capture, release, and counter modelling elements. The resources are the basic employees and workers assigned to work on the phases of the Waterfall model. The advantages of proposed method. From the study, a simulation model is suggested for simulating the Waterfall software development life cycle using Simphony.NET. In fact, the Simphony.NET is useful because it provide a ranked modelling feature which a project can be represented by an abstracted model at a higher level that contains a limited number of modelling elements and relations. The Waterfall model is enable to understand and easy to use. Furthermore, the phases of this model are processed and finish one at a time without overlap. The results or outcomes. (As mention, same as Step 6 in III) Suggestions for improvement or future work. (As mention, same as Step 7 in

    Introduction A company’s success is measured by how well it is structured and organized in order to adapt to the changes in environment as well as the changes within itself such as the company’s scale, employees, product scope, etc. Having a suitable, well-structured organizational frame will not only increase the chance of being success but also prolong the company’s lifespan compared to an un-structured one. It is important to note that an organization’s structure needs to fit in with the current situation and does not necessarily required remain unchanged over time. Taking Dynacorp as an example, even though its functional structure contributed to the vast growth of the company at the start, its limitation in dealing with the changes within

    Combining views By adopting layers as the basic component of work assignment and implementation, we will combine the allocation views (implementation and work assignment) with module views (decomposition) for each stakeholder. Before the work assignment is assigned a value it is important to know which module is allocated to which layer. This way module decomposition and layers go along with each other and by making this decision it reduces three views from the system architecture. Rationale Reason behind choosing the component and connector view is to display the concurrent process execution between the system components.
