Abstract This paper documents the analysis, design and implementation of the System Development Project for Bead Bar. The project will look into the reconstruction and augmentation of the network structure, application, database file system and mobile options. The systems development life cycle in this project because of its complexity, will be divided into smaller, more easily managed segments or phases. Segmenting the project allows managers to verify the successful completion of project phases before allocating resources to subsequent phases. Introduction The hardware and software development of this project will typically include planning, design, development, testing, implementation, and maintenance phases. However, the phases may be divided differently depending on the organization input. For example, initial project activities might be designated as request, requirements-definition, and planning phases, or initiation, concept-development, and planning phases. For this project we will be using a typical structured outline. The end users of the system under development will be involved in reviewing the output of each phase to ensure the system is being built to deliver the needed functionality. The subcomponents that play a role in the project need to fulfill some certain requirements. These requirements come out from the end user recommendations, and the features that will be available in the new version. The initial Planning Phase will produce an outline of the project. Serving as the basis for acquiring the resources needed to achieve our definitive goal. Outline inserted for review: Business Considerations: Strategic business and technology goals and objectives; Expected benefits measured against the value of current technology; Potential organizational changes regarding facilities or the addition/reduction of end users, technicians, or managers; Budget, scheduling, or personnel constraints; and Potential business, regulatory, or legal issues that could impact the feasibility of the project. Functional Requirements: End-user functional requirements; Internal control and information security requirements; Operating, database, and backup system requirements (type, capacity, performance); Connectivity requirements (stand-alone, Local Area Network, Wide Area Network, external); Network support requirements (number of potential users; type, volume, and frequency of data transfers); and Interface requirements (internal or external applications). Project Factors: Project management methodology; Risk management methodology; Estimated completion dates of projects and major project phases; and Estimated costs of projects and major project phases. Cost/Benefit Analysis: Expected useful life of the proposed product; Alternative solutions (buy vs. build); Nonrecurring project costs (personnel, hardware, software, and overhead);
The initiation phase of a project is not complete without a clearly defined goal and realistic, measurable objectives that describe the business benefits which are expected to be delivered upon completion of a project (Laureate Educatio...
The first part has a list of outdated software, legacy system. They are commonly referred to by their names such as MAS, SQL, Adhoc and other slight variations. What makes our project complex is that the systems are not operating on the same level. Some keep only our transactions and the other systems contain financial data that is booked for record. To transform all that into one system requires understanding the design of the legacy systems. Unfortunately, some of the design is not intuitive but after going through iterations of mathematical formula, you can validate some of the data. The second part called “proposed” has a list of the newer software that can be a one stop place for all data. When the project ends, the sections in the table above will be available in
This phase is the main focus of the project managers and stake holders. Meetings with managers, stake holders and users are held in order to determine the requirements like; Who is going to use the system? How will they use the system? What data should be input into the system? What data should be output by the system? These are general questions that get answered during a requirements gathering phase. After requirement gathering these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied.
Any project that strives to be a success has to have adequate planning as well as the proper resources in place. In order for the system implementation process to progress smoothly there must be several resources in place which include human, hardware, software, technical, and financial. When Brewton Enterprises’ system has begun the startup process the most important of these resources during this time period will be hardware, software, technical, and financial.
Being the present manager and being appointed by the government at the feasibility stage I am asked to write a report in order to outline the activities required to successfully manage this major project and to ensure that it is completed on time and within budget.
Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
Adding new features during development is not allowed, thereby helping in finalizing delivery date. Requirements and are well defined.

One way to provide clear description of a project is to prepare project charter. A Guide to the Project Management Body Of Knowledge (2008), “it is the process of developing a document that formally authorizes a project or a phase and initial requirements that satisfy the stake holder needs expectations” (pg.71). Preparing a project charter is the initial step for project manager to start any project. In Project charter we can describe different components of the projects. To start any project, preparing a project charter is the initial steps for project manager. Some of the essential components are described below.
The system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.
The role of planning in this project is very important. We have to address a few straightforward questions:
As discussed, this project and its requirements highlight areas where future work/improvements can be made to increase the project and the outcome. The timeframe put on this project is something which can be changed to deliver a full implementation rather than “vanilla functionality” which would later need to be modified. Another factor to consider delivering a full implementation would be the capital investment which is used for this project as this needs to be topped
Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
Preliminary Assessment requires sufficient research, huge amount of data, experts advice on impacts of project, extent of impacts and briefly evaluate the importance to decision makers.
