Systems Development Life Cycle has historically been a very useful tool in the development of software and operating systems in Computer Information Technology. Through the Systems Development Life Cycle there are at least five distinct phases that are delineated and performed within a linear patter. Meaning, that each step must be complete or at least very close in order for the next set of experts to begin the next phase of work on a project. It has been historically thought that each stage's crucial addition to the whole project is a building block necessary for the next phase of project development, therefore circular or spiral models, where all or some phases occur simultaneously was thought difficult to impossible for application within the information technology application. (Kliem & Ludin, 1994, p. 12)
The five required stages of SDLS are Planning, Analysis, Design, Implementation and Maintenance. This work will give a detailed analysis…...

Systems Development Life-Cycle is a framework for an evolution from abstract ideas to a concrete reality
Systems development life-cycle (SDLC) is a structured process of systems development is an evolutionary process that proceeds from a broad concept of information requirements and finally ends into the manufacturing of a product -- development of a new system. From this conception it can be seen that the ideas of SDLC begin to narrow down from an abstract concept to the concrete reality.
In a broad sense, SDLC starts with the following five steps-- investigation, analysis, design, implementation, and maintenance. While all of the activities in different steps are interrelated and interdependent, therefore in reality many of these steps run concurrently. However, the critical point cannot be denied that SDLC is an evolution from abstract ideas to the reality.
The first two steps -- systems investigation and systems analysis -- are abstract concepts that deal with…...

However, the company did feel it should develop its own Database infrastructure that would work with the new underlying database management system and would mesh with existing organizational skills and the selected enterprise software solution.
Because the company followed a standardized implementation process, they were able to successfully reengineer their existing business structure. The objective of the System Development Life Cycle is to help organizations define what an appropriate system development methodology should be in order for them to continue to meet the rapidly changing business environment. The specific research approach employed by International Lumberyards, Inc. was to follow the steps of the cycle and it helped them dramatically.

system development life cycle (SDLC) approach to the development of Information Systems and/or software is provided. An explanation of SDLC is offered, with different models applied in implementing SDLC delineated. Advantages and disadvantages associated with each of the models will be identified.
System Development Life Cycle
According to Walsham (1993), system development life cycle (SDLC) is an approach to developing an information system or software product that is characterized by a linear sequence of steps that progress from start to finish without revisiting any previous step. The SDLC model is one of the oldest systems development models and is still probably the most commonly used (Walsham, 1993). The SDLC model is basically a project management tool that is used to plan, execute, and control systems development projects (Whitten & Bentley, 1998). System development life cycles are usually discussed in terms of the conventional development using the waterfall model or the prototyping…...

This process places the user in a central position for both determining system requirements and ensuring they are met.
The benefits of these systems include not only improvements in user efficiency, but also others, such as reduced training costs, reduced user errors, reduced maintenance costs, and increased customer satisfaction. However, the chief requirements in these kinds of systems become to understand the users' information needs. As we argued earlier, the systems analysts cannot determine information needs scientifically, rather the system analysts are required to obtain this needs by projecting an extrovert interpersonal style that fits more closely to an art form.
Design evaluations and maintenance are carried out with users of the systems (Smith and Dunckley, 2002). Although we believe that most of maintenance is routine, but in critical cases how systems are made usable so that users do not suffer their work requires an understanding of working around the system. This…...

Health Information Technology Systems Life Cycle or HIT systems life cycle has several broad categories. One such broad category is EH or electronic health records. EHs are patient-centered, real-time records. They allow users to get information instantly wherever and whenever it is needed. Simply put, EHs are computerized, digital versions of a patient's paper charts. EHs contain the medications, radiology images, test and lab results, immunization dates, medical history of a patient and offers access as well to evidence-based tools a provider may use to make decisions concerning a patient's care. Not only does it offer streamlining and automation of the providers' workflow, it also increases accuracy and organization of patient information.
Security and maintenance is the end phase of any basic system development life cycle. The entire process is used to recognize, examine, and design information systems (Vallette & Caldwell, 2013). In order to aid in accomplishing such an…...

System Design: Oahu Base Area Network
The aim of this paper is to examine and discuss the Navy's decision to build the largest local area network (LAN) connecting the U.S. Pacific Fleet using information-gathering techniques and design methods. The system has the capacity to connect sailors and marines within the 102-million square miles of the Pacific Fleet's command coverage. Moreover it will provide the indispensable access for supplying and training the U.S. Navy. The Oahu Base Area Network (OBAN) will be the largest LAN in the world when all the phases are complete. It was started way back in 1998. It is the supporting network for the six naval commands in the Pearl Harbor, Hawaii area. Phase one has been completed. Other phases have begun in San Diego, the Pacific Northwest and the Pacific Far East, following the original business model (Kaylor, 2000). The uniqueness of this system is in its…...

The Case for ejecting Outsourcing the IT Department
The data and information within an organization is its life blood, it was what makes one company differentiated from another and valuable to customers. With IT being at the center of the information engine of any business, the idea of outsourcing it, allowing a third party company to manage this vital aspect of the company's health is like allowing a podiatrist to do heart surgery. It's not going to end well for either the doctor or the patient. The costs and benefits of IT outsourcing are presented in this analysis. Granted, IT outsourcing of menial, low-end tasks shows potential for streaming the operations of a business, allowing it to concentrate on its core business more effectively (Goo, Huang, Hart, 2008). Conversely outsourcing all aspects of IT can lead to a company abdicating its leadership in its main markets by sacrificing its core…...

Network gives us two basic advantages: the facility to communicate and the facility to share. A network helps in communication between users in better ways than other media. E-mail, the most well-known form of network communication, offers inexpensive, printable communication with the facility of sending, reply, storage, recovery, and addition. Network supports collaboration with its capacity to share. This is the main charm of popular software called groupware that is created in such a way to allow many users to have electronic meetings and work alongside on projects. (Basic Networking Concepts)

ationale for the use of life cycle Management at Glazers
LCM (Life Cycle Management) is a framework which manages and scrutinises the performance and sustainability of services and goods. This framework aims to achieve the long-term objectives of the business, and gives less stress on the short-term objectives. For getting a more sustainable value chain, organizations are making use of this framework, which would in turn improve their economic and social performance. Businesses throughout the world are making use of this framework for many purposes, like to improve their standing within the market, to strengthen the relationships with the stakeholders and to produce more environment friendly goods.
LCM urges the companies to look away from their own processes, and focus on activities which are not under the direct control of the company. Such activities include the upstream and the downstream operations that become a part of value chain. In previous days,…...

Acquistion of Information Systems
Selection and Acquisition of Information Systems
Selection and acquisition of information systems could involve an enormous investment for a healthcare organization. Besides the initial costs that organizations need to incur, there are also long-term costs associated with maintenance, support and enhancement of the information system. Selecting the right information systems that would meet the need of an organization is a critical step to consider when selecting and acquiring the information systems. To select information systems, it is critical to evaluate the costs and benefits as well as gaining insight on the full constituents of the users.
Fundamental objective of this paper is to discuss the process of selecting and acquiring the information systems for our healthcare organization.

Evolution of Healthcare Information System
Evolution of health care information system
Over the last twenty years, technology in provision of healthcare has evolved tremendously and what was available then now seems primitive in comparison. Today, patient care is at a much higher level. The management of healthcare institutions has become far more efficient through the growth of technology. esearch is now more readily available. The growth of technology has proved beneficial to not only the healthcare workers, rather, more so to the patients. Nowadays, treating a patient correctly and effectively is easier than it was then; the patient is also more secure due to machines that can monitor all his processes and new technology has also enhanced the skills of the healthcare workers in handling their patients (Bavova, 2013).
This paper seeks to discuss highlight similarities and differences between healthcare provision twenty years ago and today, as a result of technological developments. The…...

electronic medical records have yet to become standardized in the United States, the contemporary physician's office differs significantly from one from twenty years ago. Information systems govern multiple aspects of care delivery, from patient intake, processing, and billing to medical records, access to electronic scholarly databases for knowledge management to purchasing and human resources management. Understanding issues like the system development life cycle (SDLC) and project management life cycles have now become common practice in most healthcare offices, whereas twenty years ago only the most cutting edge of those offices would have dedicated information technology specialists who would handle and address matters like product life cycles. Full time consultants or advisory positions related directly to IT are now expected of most medical practices. Since the Health Insurance Portability and Accountability Act (HIPAA) was passed just over twenty years ago, physicians offices have made significant strides by incorporating informatics into…...
