Developing software is far from an exact science and without a structured system to guide the process a project is likely to fail. Defining and adhering to a Software Development Life Cycle (SDLC) early in the project will help to guide the development of a new information system. In addition to having the structure for the development team to work within a defined and agree upon SDLC will help to set the proper expectations for deliverables with the stakeholders and customer(s). Smith Consulting has been given the task of creating a Frequent Shopper program for Kudler Fine Foods. As a result Smith Consulting needs to decide on which SDLC will work best for this project. In addition to selecting a SDLC to use Smith Consulting will
Another factor to ensure success is to train the IT personnel on the system’s applications and processes. How well the IT personnel understand the systems is extremely relevant to the success of system implementation. The involvement of IT personnel, who have knowledge regarding the application requirements, increases the ability of the team to correctly and quickly specify the requirements. Experienced IT personnel on a team help ensure others understand terminology and have more of an understanding of the stakeholders needs (Havelka and Lee, April 25, 2002).
A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been
The challenge is some of the past development work was done by a consultant. We have option to scale the current work which is not an industry standard and end up paying more money and band aids fixes or develop a new program that we can design and manage for our future growth knowing future growth is inevitable. The risk of continuing the current information system program is low for now, but it will be a major replacement issue for the future growth that could cost the company millions and lost business opportunities. Developing a new information system program is a risky choice from time
Full implementation should be completed in six months. The boundaries are the human resource system. Crossing over into design or inclusion of other departments such as accounting or sales would be out of scope. The business requirements are that the system is to be a single system instead of the multiple tools they are using now. The other business requirement is more vague, only stating that they would like to take advantage of more sophisticated, state-of-the-art technology. Project feasibility is determining if the technical, economical, and operational factors of the project can be accomplished under the schedule given. Technical looks at what hardware and software are available compared to what the requirements of the project are. Economic compares the cost of the overall project to what is budgeted and what can be justified by potential financial returns. Operational factors examine if the system will receive support from the people that use it and make it work (“System Development Life Cycle”, 1998).
Generally, the acquisition of a new information technology (IT) system begins with the process of surveying all of the component parts of the organization to determine what specific functions are required and expected of the new system (Halbert & Ingulli, 2009). That process distinguishes between functions that are absolute necessities and those that may be desirable and beneficial or convenient but that are not necessarily absolute requirements. More particularly, the IT acquisition team would endeavor to understand enough about each organizational component or business unit to provide guidance and to participate in a determination of what specific system features and capabilities are justified in connection with their perceived value to the users in relation to their cost and to any other considerations
The previous two parts of this three-part assignment, the systems analysis and application architecture and process design aspect of the credentialing software project at TPI Health Systems (TPI) was explored. This last paper will explore the implementation stage of the systems development life cycle (SDLC) as it related to the credentialing project at TPI.
The current development process devotes a large amount of time at the front end of development to establishing customer needs and converting them into system level requirements. The client-site team meets with customers, learns their needs, develops specifications, verifies them with the customers, and then sends them offshore for development. This is a very formalized, documented process. (+)
Given that the development of new systems can be fraught with problems and delays, there are many factors that drive organisations to develop new systems. The most important drives come directly from the companies needs and are often not related to technology, but however to technological solutions, these include:
Thankfully guys for your comments/discussion too. I have been working hard with my degree completion plan, because God always help me to understand. With this course I learned how is important to use the SDLC for every goal, “The SDLC has a similar set of four fundamental phases: planning, analysis, design, and implementation. Different projects might emphasize different parts of the SDLC or approach the SDLC phases in different ways, but all projects have elements of these four phases. Each phase is itself composed of a series of steps, which rely upon techniques that produce deliverables (specific documents and files that provide understanding about the project).” (Mckay and Marshall,
When designing any new system special considerations, guidelines, and specification should be taken into consideration. It is best practice that as many people as possible participate in the project, adding some sort of
Involved in all the phases of Software Development Life Cycle (SDLC) including Requirements Gathering, Analysis, Design, Development, Testing, Production and Post-Production Support
Problem Statement: When a system has requirements that are not well defined, needs to be stable, is complex, or is using a new technology and there is a need for fast development, it is hard to
In this type of testing the one, one and small part of program is testing and find the errors during this testing when the errors found and highlight the errors and later fix these errors. The testing of this type is easy and take less time. When this step of testing is completed then the next step of testing is performed.
The central part of the testing process of system is that- to work with all the deformities and problems arise in the LMS project. The program was basically went through different process and levels of testing like giving various inputs to check and deal with the outputs, according to that outputs the next step is to decide whether program is working correct or not , or it still needs few corrections. Basically every project is going through 2 levels of testing-
