...conducted such planning in all core business units such as Marketing, Finance, Human Resources and IT in the hopes that the aforementioned strategies translate into some degree of competitive advantage. The process within IT to achieve objectives or improve operations can be accomplished through The Systems Development Life Cycle (SDLC). Through a series of processes or steps as prescribed by the SDLC methodology, a firm can find the answers to a business situation and thereby improve operations and hopefully attain a competitive advantage. This paper will address the importance of the Systems Development Life Cycle Methodology to organizations. SDLC and Benefits The SDLC is a problem-solving process which through a series of steps helps produce a new computer information system. Each step from system planning, system analysis, system design, system implementation and to system maintenance conducted in sequence should provide the answers to a problem or opportunity (Farah, 2006). An example may be a user which employs an order system may sense a problem with that system because customers may complain that orders are late or being lost. The SDLC through the steps previously mentioned would help correct and improve the system and operations of the order entry process (real life situation at KCI Medical Canada-Vancouver office). In this example, the system planning phase determines whether a new order...

...Homework Assignment 2 1. There are four phases in the systems development life cycle (SDLC). These phases include systems planning and selection, systems analysis, system design, and system implementation and operation. The first phase is system planning and selection, which identifies the need for building information systems. This phase also covers the scope, cost, and schedule of building information systems. The second phase is the systems analysis phase, which is the actual study of the current procedures and the requirements needed. The third phase is system design, which is broken into two parts called the logical design and physical design. The logical design concentrates on the business aspect of the system, whereas the physical design pertains to the technical specifications. Finally, the fourth phase is the system implementation and operation phase. This phase implements the system by installing the hardware or software of the system. Other forms of implementation include programming, user training, and documentation. 2. If someone at a party asked me what a business/systems analyst was and why anyone would want to be one, I would first explain what a business/systems analyst is. I would tell them that a business analyst studies the problems and needs of an organization and determines the best approach to solving those needs. I would also tell them it is a job worth wanting because it is one of the best technology jobs in the field today. 3. It...

...in a very deliberate, structured and methodical way , reiterating each stage of the life cycle. The systems development life cycle, according to Elliott & Strachan & Radford (2004), " originated in the 1960s, to develop large scale functional business systems in an age of large scale business conglomerates. Information systems activities revolved around heavy data processing and number crunching routines" . Several systems development frameworks have been partly based on SDLC, such as the Structured Systems Analysis and Design Method (SSADM) produced for the UK government Office of Government Commerce in the 1980s.Eversince, according to Elliott (2004), " the traditional life cycle approaches to systems development have been increasingly replaced with alternative approaches and frameworks, which attempted to overcome some of t he inherent deficiencies of the traditional SDLC" .

...System Development Life Cycle System Development Life Cycle (SDLC) is a project management technique used to divide complex projects into smaller and more manageable segments or phases. The software development projects include initiation, planning, analyzing, design, programming, testing, implementation, and maintenance phases. Through the feasibility study task the system is investigated to use the existing program or to change it. Once the decision is made through the feasibility analysis the decision is made to move forward or not, which is called the “Go/No-Go” (Rainer & Turban, 2009). The system analysis examines the problem in the business and makes plans to enhance or create a new system through an information system. To make sure if the system will be able to complete the assignment is done through the systems design. This function has two aspects, which is the logical design and physical design (what and how). Programming transfers the designs into computer codes. Testing requires the system to continuously check to see if the computer codes will produce the end results that are expected. To convert old information to a new system is the implementation stage. The converting is three stages of implementation, which is direct, pilot, and phased. Once the old system is replaced and the new system is stabilized audits are performed. In addition, maintenance is done, the first type of maintenance is debugging- this is done throughout the life of the system. Updating...

...1) Planning Phase During this phase, the group that is responsible for creating the system must first determine what the system needs to do for the organization (requirements gathering), asking questions such as: What is the system needed for? What will the system do for the organization? How is the system going to be made? Analysis In this phase is the group that has been placed in charge of the project must decide if the project should initialize with the resources available. This also includes looking at any existing system to see what it is doing for the organization and how well that system is doing its job. Feasibility is also considered in this phase which gives rise to questions such as: Can the system be created with the resources presently available? Will the system significantly improve the organization? Does the old system even need to be replaced? Design This phase involves the actual creation and design of a system. This is where the team puts together the different pieces that will create the system. In a database approach, this would include the server hosting the database, software that will form the database, other needed Database Management System software. Implementation This phase involves the actual construction and installation of a system. Implementation also includes the maintenance of the system and any future updates or expansion of the system. With the database project example, the following activities are examples of...

...under a complete cycle before the end product. A systems development life cycle (SDLC) is the framework adopted by software analysts to describe the phases involved while developing IS (Shelly & Rosenblatt, 2010; Shelly & Rosenblatt, 2011). There are different System Development Life Cycle Models used in software development process. The major SDLS are waterfall life cycle, spiral life cycle, the prototyping model, and the incremental build model among many others (Rodríguez-Martínez, Mora, Álvarez, Garza, Durán & Muñoz, 2012). The aforementioned SDLC models are referred to as predictive life cycle models. This implies that the cost of designing can be predicted accurately, the scope articulately determined, and the schedule accurately predicted (Schwalbe, 2011; Shelly & Rosenblatt, 2011). The current research study is an attempt to discuss different models and compare them in detail. It also looks at Baltzan’s seven step model versus other software development models. Types of System Development Life Cycle Models Waterfall Model This model is considered among the oldest models of software development (Shelly & Rosenblatt, 2011). Primarily, the model emphasizes of early planning of its stages and completion of each stage before moving to the next stage. In projects which are complicated and with limited resources, a waterfall model is often applied. It is used as the baseline for other SDLC models...

...System Development Life Cycle In the present booming economic environment every organization plans to expand and develop quick system and encase economic boom, as soon as possible. This requires a process which can quickly develop new systems, in lesser time with lesser cost. This presentation will focus on the process of how to achieve the development goal. What is SYSTEM DEVELOPMENT? We are talking about the development of a system or business so first we should understand what development is: - “System Development” refers to the process of – * Examining a business situation, * With the intent of improving it, * Through better procedures and methods. System Development is having two major components in it * System Analysis – Analysis of current system for Problems & Demerits in it and Additional requirements in new system * System Design – Process of planning new system which will replace the old one Beginning of a System Development System Development usually begins when a problem or opportunity is identified by Managers, it can be because of any of the followings: * New design idea to smoothen the process in the organization. * Evolving environmental changes such as Competition. * Adding new business or product line to present business. * Present system does not satisfy the users information needs. * Present system no longer efficiently and effectively meets the Goals of organization. * Excessive time spent in correcting...

...KFF Network Design NTC/362 – Fundamentals of Networking Tom Krawczyk September 12, 2015 Primer Information technology is an essential part of many businesses today, and this is evident in the ways many companies are increasingly relying on their computers to optimize their businesses. It is also not uncommon for businesses of distinct sizes to utilize multiple computers in their offices, with these computers interconnected through networks to allow information sharing between computers. Computer networking is even more required in businesses with multiple offices, and these locations could sometimes cut across different geographical boundaries. Kudler Fine Foods (KFF) epitomizes such business concerns that optimize its with computer networking. The company, located in San Diego, was founded in June 18, 1998, and it is a local specialty food store with three locations within the USA. However, the organization has evolved since its formation and seems to have outgrown its present network infrastructure. As such, to successfully compete in ever challenging business climate, KFF requires enterprise upgrade, and the goals of proposed network are modern technologies for data collection, information protection, and enterprise communication coupled with optimal data speeds and network access. This upgrade will not only enable transform KFF into a 21st century organization, but it will also enhance its productivity and giving it...

...Systems Development Life Cycle Elements Julie Lauck BSA/376 February 11, 2015 John Neels Systems Development Life Cycle Elements The Systems Development Life Cycle (SDLC) is a general tool business and organizations can use to develop and implement new information systems. The projects can be large or small. The SDLC involves a variety of steps, elements or phases, and personnel to complete the project. Essential Elements of the SDLC The process of the SDLC can be described like so: “is first conceived as an idea; then it is designed, built, and deployed during a development project; and finally it is put into production and used to support the business” (Satzinger, Jackson, & Burd, 2009, Chapter 2). The four formal elements of the SDLC are the planning, analysis, design, and implementation phases. These phases make up the framework for the project and break down the task of management. The course mentioned a fifth phase (support) that involves routine testing and monitoring of the final implemented information system (Satzinger, Jackson, & Burd, 2009, Chapter 2). Planning The first phase has been noted to be the most important. The business or organization recognizes a significant problem has to solve. Analysts will then work to produce a timeline or schedule of events that must occur up to project completion. The project must be reviewed to validate feasibility. Project...

...SDLC Value Paper X.X. Xarris BSA/376 March XX, 20xx Professor B. Anders SDLC Value Paper A systems development life cycle (SDLC) is more or less the life of a business. An SDLC is one of the key elements that support an organization’s information system. According to Satinzer etal, 2009, “the life of an information system, it is first conceived as an idea; then it is designed, built, and deployed during a development project; and finally it is put into production and used to support the business.” There are numerous approaches used during the life cycle development. One approach is a more definitive method with risks that are relatively low, this approach is predictive. Meanwhile, on the other hand another approach that is more undefined, with risks that are much higher technically, because there is no well-defined understanding of what the user needs are, this approach is known as adaptive. There are many employees (project manager, system analyst, developer), as well as others (customers, investors, and even suppliers) who have a stake in and are involved in the SDLC process, their roles differ largely as well. The role of the Project Manager is central to the entire SDLC process, this individual is involved closely, and is very much needed, and without management being heavily involved it is likely the process will fall apart. Project managers ensure that there are no resource shortages, such as staff, budgetary requirements, and other necessary elements that...

...Traditional System Development Life Cycle Planning: To generate a high-level view of the intended project and determine the goals of the project. The feasibility study is sometimes used to present the project to upper management in an attempt to gain funding. Projects are typically evaluated in three areas of feasibility: economical, operational, and technical. Furthermore, it is also used as a reference to keep the project on track and to evaluate the progress of the MIS team. The MIS is also a complement of those phases. As software is always of a large system (or business), work begins by establishing the requirements for all system elements and then allocating some subset of these requirements to software. This system view is essential when the software must interface with other elements such as hardware, people and other resources. System is the basic and very critical requirement for the existence of software in any entity. So if the system is not in place, the system should be engineered and put in place. In some cases, to extract the maximum output, the system should be re-engineered and spruced up. Major function: This step involves identification of potential projects in which the firm may engage. Some of the sources for project ideas include user departments, steering committees, top-level managers and brainstorming sessions. The guiding factors while identifying potential projects are the needs of the organization and the weaknesses of the current systems. After the...

...System Development Life Cycle Models Anusha Gujjula IST.8100: Integrating the Enterprise, IS Function/Technology Wilmington University Abstract SDLC aims to develop an information system by using some of its methodologies, which are clearly explained below. The paper also describes about some of its phases and their uses. This paper gives us an idea to the Project managers, developers and trainers about the basis of the model being used for their project and to decide which SDLC model would be suitable for their project retrieved from (Samdani, 2005). The development of a project or a business unit of an organization is depended on it. So by considering it a detailed analysis of the requirements had been carried out. The prevailing life-cycle-based models do not explicitly deal with changing organizational attributes during the development process.

...SDLC and Agile Methodologies Ricardo E. Reyes BSA/375 February 10, 2014 Michael James, IT Program Instructor SDLC/Agile Methodology Differences The Systems Development Life Cycle, better known as the SDLC, is an Information System development method which is founded upon its four fundamental phases: * * Planning * Analysis (& Design) * Design * Implementation Although these four phases are sometimes approached in a few different ways, the basic concept remains the same; each phase of the development method is addressed in a typical SDLC approach. The approach may sometimes be done consecutively, incrementally, or in other manners dependant on the situation. SDLC methodology is better suited for larger projects, in addition to a larger audience. Although this process requires as much input as possible (during the Analysis phase) from people who will work directly with the new system, this same requirement will normally diminish as the development process continues with the rest of the other phases. In comparison, the Agile methodologies are a collection of alternate (more fluid and adaptive) approaches made from several different system development methods. A document by the name of The Agile Manifesto addresses these common aspects of the various methodologies under the Agile Methodologies umbrella. One of the key principles which constitute a specific methodology as part of the Agile Methodology would be that the methodology will be very...

... 2002). The controller reviewed the training budget and identified higher than budgeted costs related to emergency training on new systems. Furthermore, override approvals demonstrate the lack of new project training costs in the product development budget unless coded to the wrong cost centers. The director of human resources verified training was not incorporated into the project training costs. The executive board approved distance learning solution project to address these rising and unbudgeted costs. With an $80,000 budget this project leads training through teleconferencing. A systems development life cycle (SDLC) provides an organization with a process for success in meeting the strategic goals in phases (University of Phoenix, 2013). This is the simplest methodology to organize a project. The purpose of this paper is to demonstrate how an SDLC provides Riordan with the necessary tools to meet the organization’s needs in the timeframe and cost constraints outlined by the executive board. Project Planning The project identified by the controller is distance learning through teleconferencing. The project provides a solution to training costs excluded from the project budget. Additional rationale behind the project includes high travel costs associated with emergency training sessions. Project requirements that are accurate, clear, and concise from management are important to achieve project success within the time and budget constraints. This phase provides a solid...
