...tion requirements. Similarly, the systems analysis, or define phase, is the deliverable which defines the system’s requirements. This includes taking the deficiencies in the existing system and addressing them with specific proposals for improvement. These proposals can be to ensure that the new EHR has all the necessary requirements to qualify for certification and help to narrow down vendor selection. Incorporated into the SDLC is a maintenance phase in which constant upkeep and evaluation is needed to ensure an operational system that is properly maintained, supported and secured. During this phase, system users should be kept up-to-date about the latest modifications and procedures. It is therefore important to know that your vendor has a good standing reputation and plans to provide continuous support for your software throughout the product’s lifecycle.
In order to complete, many projects are finding it advantageous to use a lifecycle approach. One of the reasons software project management remains a challenge is that, as has been all too frequently observed, progress in software development has not kept pace with progress in hardware development. The gap between software and hardware development is partly explained by the lack of standard methods and tools to boost the software development process. In short, "The cobbler's children have no shoes."
Ans: SDLC is a process followed for a software project, within a software organization. It consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.
The initiation phase of the United States Department of Justice (DoJ) System Development Life Cycle (SDLC) is similar to this situation. Management of a business or organization determines that it is necessary to enhance a business process through the application of the computer system or information technology. There are certain requirements that will be followed during this phase of the SDLC. First, there must be a need for improvement of a current process or the potential for a new process. Second, there has to be a sponsor for the project, usually someone from the executive management level or a current supervisor. And third, depending upon the type of business, a demand from the public to enhance or make improvements upon a service currently being delivered or create a new service based upon public demand.
d. System builders – are another category of technology specialist for information systems. They role is to construct the system according to the system designers’ specifications. System builders focus in one or more of the fallowing: applications programmers, systems programmers, database programmers, network administrator, webmasters, and software
The planning process depends on a formal information system. The external and internal assessments provide a reality base on which to build future plans. The vision or mission identifies the organization's purpose and its desired future state.

Stress testing the system and training the users plays a very important part in implementing our design. We will monitor the system, train IT staff and train all users on our newly implemented system. After some time has passed user satisfaction surveys will be issued to our user community for productive criticism and feedback. During this time system documentation will be created. Last but not least, a project team meeting will be conducted for review of failures and successes. A main objective of this meeting will be how to improve our team processes and take note of any tasks that can be streamlined for our next project. As closure for this project we will have one last meeting with Ms. Reynolds and management for final sign off on this project.
A majority of all change management projects are systems driven. "Aggressive companies are accelerating deployment of strategic business applications to achieve market dominance" (Fournier, 1999, p. a10). For example, an organization develops a new computer interface in order to help serve customers more effectively and efficiently. With the new system, employees have access to more account information that, in turn, requires less follow up time, and the customers’ request is handled faster. Furthermore, this new system will support new business initiatives that are scheduled in the near future. Change and configuration management strategies are necessary "…to ensure system reliability" (Fournier, 1999, p. a10). Configuration management is defined as "…the IT process concerned with identifying, documenting, controlling, and tracking the configuration of interrelated IT components, at discrete points in time, throughout the development or maintenance life cycles" (Fournier, 1999, p. a10). Moreover IT components are also known as configuration items, comprise "…a variety of interdependent software, hardware, and networking components" (Fournier, ...
The System Development Life Cycle (SDLC) plan includes six phases. These six phases are The Preliminary Investigation Phase, The Analysis Phase, The Design Phase, The Implementation Phase, and The Maintenance Phase. (1) If this plan had been followed there would have probably been much different results.
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).
The team implementing the new system were required to do both functional and systematic requirements thus affecting the implementation of the new system

Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
