...Phases of the traditional Systems Development Life Cycle (SLDC) for Bank ATM Software David Phillip Piña University of Phoenix Abstract This paper will attempt to explain the six different phases in a traditional systems development life cycle for developing software to run a bank’s automatic teller machine (ATM) machine. The input and output for each phase will be clearly outlined. Information from my Week 1 CIS/319 class readings will be used as a guide. Phases of the traditional Systems Development Life Cycle (SLDC) for a Bank ATM The Six Phases According to Moore, W., Nolan, E., & Gillard, “There are six different phases in a traditional systems development life cycle. The first phase is preliminary investigation, the second phase is system study, the third phase is system analysis, the fourth phase is programming and implementation, the fifth phase is support and maintenance, and the sixth phase is documentation”. (2006) According to Computer World, “Stages of the traditional system development lifecycle can be characterized and divided up in different ways, including the following: Project planning, feasibility study: Establishes a high-level view of the intended project and determines its goals. Systems analysis, requirements definition: Refines project goals into defined functions and operation of the intended application. Analyzes end-user information needs. Systems design: Describes desired features and operations in detail, including...

...1.4 THE PHASES OF SYSTEM DEVELOPMENT LIFE CYCLE Before get on to the phases of the System Development Life Cycle (SDLC), come we make clear our-self on the definition of the System Development Life Cycle (SDLC). System is a wide and a common term and is an exercise of mutually beneficial or interacting elements forming an integrated whole which a term that can be utilized in different industries. Hence, System Development Life Cycle (SDLC) is a constricted term that states the of six main stages to creating hardware system only, a software element only or that mixes with other software components to create the whole system of both to meet or exceed customer’s expected values. From the below figure 1 we can understand on the basic six phases...

...Systems Development Life Cycle The systems development life cycle (SDLC) is the overall process for developing information systems from planning and analysis through implementation and maintenance. The SDLC is the foundation for all systems development methodologies and there are literally hundreds of different activities associated with each phase in the SDLC. Typical activities include determining budgets, gathering system requirements, and writing detailed user documentation. The activities performed during each systems development project will vary. The SDLC begins with a business need, followed by an assessment of the functions a system must have to satisfy the need, and ends when the benefits of the system no longer outweigh its maintenance costs. This is why it is referred to as a ‘lifecycle’. The SDLC is comprised of seven distinct phases: planning, analysis, design, development, testing, implementation, and maintenance. This section takes a detailed look at a few of the more common activities performed during the phases of the systems development life cycle along with common issues facing software development projects (see Figure D.1 and Figure D.2 ). Phase 1: Planning The planning phase involves establishing a high-level plan of the intended project and determining project goals. Planning is the first and most critical phase of any systems development effort an organization undertakes, regardless of whether the effort is to develop a system that...

...Information System Development. Information system is a collection of hardware, software, and procedures work together to produce Quality Information. Information system MUST meet the requirements of the SYSTEM USER. SYSTEM DEVELOPMENT is a set of activities that you need to develop an INFORMATION SYSTEM. There are many types of information systems; Ø Office information system; is an information system that lets employees perform tasks electronically using computer and electronic devices instead of manual systems. Ø Transaction processing system; is an information system that captures and processes data generated during an organisations day to day activities. Ø Management information system; while computers were ideal for routine transaction processing, managers soon realized that the computers’ capability of performing rapid calculations and data comparisons could produce meaningful information for management. Ø Decision support systems; Transaction processing and management information systems provide information on a regular basis. Frequently, however, users need information not provided in these reports to help them make decisions. A sales manager, for example, might need to determine how high to set yearly sales quotas based on increased sales and lowered product costs. Decision support systems help provide information to support such decisions. Ø Expert systems; An expert system is an information system that captures and stores the knowledge...

...Bus 220: Business Communication and Information Systems M8A1: Final Examination June 20, 2013 1. Explain virtual reality. Provide three examples. Virtual reality (VR) is a system “that enables one or more users to move and react in a computer-simulated environment.” (Stair & Reynolds, 2012, p. 337) Virtual reality applies sights and sounds in an artificial environment where human actions determine to an extent, what occurs inside the environment. Today, virtual reality is used in communication, training, and treatment in a spectrum of areas including the medical field, entertainment, and education. Medical VR systems “provide a new human-computer interaction paradigm in which users are no longer simply external observers of images on a computer screen but are active participants within a computer-generated 3D virtual world.” (G & B, 2002) Inside the world of virtual reality, medial applications such as three dimensional visualization of anatomy, telepresence surgery, complex medical database visualization, rehabilitation, surgical simulators and virtual surgical equipment as well as virtual operating rooms are emerging. Facilitated through computer interface, these medical applications of virtual reality are essential in the field of medicine. These applications allow individuals to learn human anatomy by “flying inside and around organs.” (Satava, 1995) The purpose of VR systems in the medical field is to ultimately develop a digital physician.

...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...

...The Opportunity Costs of Systems Analysis and Design Date: 24 March, 2010 For a specific application, the first task is to decide which methodology is appropriate for its development. The structured system analysis and design (SSAD) method has been fine-tuned and used for many years in the real world. However, during the last several years, object-oriented approaches towards analysis and design (OOAD) have become increasingly more popular and more widely used in industrial organizations all around the world. The OOAD strategy approaches the problem from an object point of view as opposed to a functional perspective, which is the primary focus of the traditional structured development methodology. Over the years, the increasing use of OOAD over the traditional structured development methodology has spread significantly, throughout the many levels of production and in various projects. As newer and more sophisticated object-oriented languages are created, there appears to be an even greater need for an object-oriented approach to develop business applications. While the use of OOAD methodology is justified in many cases, in some cases it may be inappropriate and we should consider the use of the traditional structured analysis in the design and development of those information systems. This paper shall begin by outlining both the traditional structured and object-oriented approach towards systems analysis and design and then discuss how the object-oriented approach...

...System Development Life Cycle (SDLC) SDLC is a set of activities which are perform by analyst and developer to create the system for software. SDLC is a conceptual model used in project management that describes the stages involved in information system development project from a preliminary study through maintenance of the complete application. SDLC follows six steps-: 1 Preliminary study 2 Determination of system requirement 3 System design 4 Software development 5 System testing 6 Implementation & Maintenance 1 Preliminary study -: Preliminary investigation is the first step in the system development life cycle. The preliminary investigation is a way of handling the user’s request to change, improve or enhance an existing system. The objective is to determine, whether the request is valid and feasible before any recommendation is made to do nothing, improve or modify the existing system, or build altogether a new one. Preliminary study divided into following 3 categories – A. Request Analysis B. Feasibility study C. Request Approval Request Analysis:- In this category, the users need is clearlyIdentify. Analyst identifies that what are the requirements of the user. Feasibility study:- The aim of the feasibility study is to access alternative systems and to propose the most feasible and desirable system for development. Thus, feasibility study provides an overview of the problem and acts as an important checkpoint that should be completed before committing more...

...IT 460 Unit 1 Kaplan University Harold Boyd The first thing I am going to talk about is JAD (Joint Application Development). Joint Application Development (JAD) is a development technique used to help IT developers build systems. This technique was developed by IBM in the 1970's. In this technique, a team is formed of members of different backgrounds. These members are made up of end-users, management, and IT staff. This team meets and discusses the current project in a number of workshops/sessions. These workshops are used to define the project and to design a solution. Since the team includes actual users of the current system, the system analyst will have a better picture of what the clients would want in a new system. There are four thoughts to consider when working in a JAD. First, the best people that understand the job functions are the people that perform those duties. Needless to say, these people are the best source of information when a question comes up about a particular process. On the other end, IT people understand the "behind the scenes" workings of the current system and can answer question on those topics. These two points introduce the third idea, which is the difference between business professionals and IT professionals. At times, business professionals do not understand subjects in the IT realm (i.e., they are "computer illiterate"). On the other side of the spectrum, IT professionals have issues understanding subject matter in the business realm (i...

Organizations use a standard set of steps, called system development methodology to develop and support their information systems. Like many processes, the development of information systems often follows a life cycle. For example, a commercial product such as a Nike sneaker or a Honda car follows a life cycle; it is created, tested and introduced to the market. Its sales increase, peak and decline. Finally, the product is removed from the market and is replaced with something else. Many options exist for developing information systems, but the most common methodology for system development in many organizations is system development life cycle. However, it is important to know other alternative development methodology available in order to maximize the development process. there are four important terminologies in information systems, namely methodology...

...implement systems to remain competitive. Software that is built correctly can support agile organizations and can transform as the organization and its business transforms. Software that effectively meets client’s needs will help an organization become more productive and enhance decision making. Software that does not meet client’s needs may have a damaging effect on productivity and can even cause a business to fail. Employee involvement along with using the right implementation methodology when developing software is critical to the success of an organization History The Systems Life Cycle (SLC) is a type of methodology used to describe the process for building information systems, intended to develop information systems 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...
