...A systems analyst uses the concept of analysis and design to maintain and improve their information systems. The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently (citation). The first steps that need to be taken in systems improvement are research and analyzing the scope and feasibility of a new project. Systems Analysis Approach The information-gathering technique and design method proposed for this project is the Rapid Application Development method, acronym RAD. The RAD methodology is a process in which research of user requirements is compiled before producing any detailed system design documents. Using this approach decreases the time needed to design and implement new systems. Factors of Successful Analysis The Rapid Application Development method incorporates using three different approaches of systems analysis. These sub-approaches are Prototyping, Computer-Assisted Software Engineering Tools, and Joint Application Design. By using the three different perspectives, RAD streamlines the entire systems analysis and design process. Prototyping Prototyping is the building of a raw and small-scaled working model. This model is an easily modified and extensible representation, simulation or demonstration of a planned software system, likely including its interface and input/output functionality (Maner...

...system life cycle is useful for large projects that need formal specifications and tight management control over each stage of systems building.” ( Building Systems History, 2012) However, this approach is very rigid and costly and is not well suited for unstructured, decision-oriented applications for which requirements cannot be immediately visualized. Prototyping consists of building an experimental system rapidly and inexpensively for end users to interact with and evaluate. The prototype is refined and enhanced until users are satisfied that it includes all of their requirements and can be used as a template to create the final system. Prototyping encourages end-user involvement in systems development and iteration of design until specifications are captured accurately. The rapid creation of prototypes can result in systems that have not been completely tested or documented or that are technically inadequate for a production environment. Developing an information system using an application software package eliminates the need for writing software programs when developing an information system. Using a software package reduces the amount of design, testing, installation, and maintenance work required to build a system. “Application software packages are helpful if a firm does not have the internal information systems staff or financial resources to custom develop a system. To meet an organization’s unique requirements,...

...that the implementation is complete and basically correct. Analysis culminates in identifying classes implied by the use cases, and documenting them using an Analysis Class Diagram.” (Russell C. Bjork Professor of Computer Science, 2004) The difference is in object oriented analysis the data is combined in a process that acts on the data in the object whereas structured analysis treats the process and the data as separate components. 2- Describe the phases of the system development life cycle, and compare the SDLC waterfall model with the spiral model? “The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), the fountain model and the...

...THE SYSTEMS DEVELOPMENT LIFE CYCLE LECTURE NOTES DEVELOPING INFORMATION SYSTEMS SOLUTIONS The Systems Development Cycle: The systems approach can be applied to the solution of many types of problems. When this involves the development of information system solutions to business problems, it is called information systems development or application development. Most computer-based information systems are conceived, designed, and implemented using some form of systematic development process. In this process, end users and information specialists design information systems based on an analysis of the information requirements of an organization. Thus, a major part of this process is known as systems analysis and design. When the systems approach is applied to the development of information system solutions, a multistep process or cycle emerges. This is frequently called the information systems development cycle, also known as the systems development life cycle (SDLC). Steps involved and products produced in the traditional information systems development cycle: 1. Systems investigation - Product: Feasibility Study 2. Systems analysis - Product: Functional Requirements 3. Systems design - Product: Systems Specifications 4. Systems implementation - Product: Operational System 5. Systems maintenance - Product: Improved System 1. All the activities involved are highly related and interdependent. 2. Several developmental activities can occur at the same time...

...retailers to attract long-term customers that demonstrate a loyal relationship between both parties (Iterative and Incremental Development Testing, 2008).This paper discusses the methods that can be used in the development of the Frequent Shopper Program by Smith Systems Consulting. Waterfall model Waterfall Model operates in a waterfall process tree. It has various phases such as requirement, design, implementation, verification, and maintenance that provide a successful execution to any system development. This model can be used in the development of frequent shopper program (Nicholls, 2005). The waterfall model's requirement phase will help Smith Systems Consulting to develop a program according to the need of Kudler Fine Foods. This model's other phases facilitate deep analysis of every aspect that provides appropriate development of the program. Each phase can be proceeded after the proper completion of the previous phase. This model facilitates Smith Systems Consultant’s advance knowledge about success or failure of the program, which helps to reduce failure risk. On the other hand, the waterfall model cannot facilitate the ability to update. In this model, information can be gathered after the process rather than during the process. This reduces flexibility to change pertaining to change in requirements. This aspect can make a faulty development as a result because it cannot be developed within the changing requirement of Kudler Fine Foods and relative environment. This...

...areas to create a system that will more satisfy the needs of staff, customers and open the doors for e-commerce as Ruben suggests. Implementing Rapid application development system (RAD) the club would be combining joint application design (JAD), computer assisted software engineering tools (CASE), and prototyping to produce a high quality system quickly (Rainer 2009). The internet connection to the office is a problem that cannot be ignored. Although the dial up connection is less expensive than the high speed internet, in some areas dial up was 14% lower in 2003 (Whitacre, B. E., & Mills, B. F. (2010) and it is still lower priced today. The main problem with this is the speed at which information can be down loaded, and streaming music and video could be an all-day affair if possible at all. This will surely not sit well with club IT consumer base of Net generation. If the club cannot keep up the pace with its own customers, then it will not be able to compete in the market for very long. They could add a second line to save little money, but in the long run the loss of client base would cost considerably more. The high speed internet will not only support the rapid application development system, but will let the club compete in Internet e-commerce. RAD Club It The main reason that club it should use Rapid application development system is because it is “…faster, better and cheaper.”( Jain, R., & Chandrasekaran, A. (2009). This system allows use of Icase tools to structure...

...Club IT Part 2 University of Phoenix XBIS/219 1/13/2012 Club IT Part 2 * After meeting with Lisa and Ruben, I came up with several ideas for Club IT to become more successful throughout. I researched several project development methodology that could bring Club IT to a whole new level as far as business and information technology. I was also able to give Lisa some suggestions on how to keep Club IT's edge as high energy and high impact as possible through club and public resources such as network applications (University of Phoenix, 2012). I have also identified three business problems at Club IT and plan on fixing those problems as soon as possible with my suggestions. The project method methodology that I have decided to go with for the company is rapid application development. I chose this methodology because it can combine a number of tools and user requirements such as prototyping and joint application design to rapidly produce a high quality system (Rainer & Turban, 2009). This methodology is important because it allows the users in the company to be involved from the start as well as speed up systems development. Three business problems at Club IT are the website, computer hardware, and Internet. These three problems are huge for Club IT because these problems are slowing Club IT's business down. By upgrading and fixing these problems, Club IT could be better than ever. Club IT's website has been a problem because the website lacks the same excitement...

...APPLICATION DEVELOPMENT Johnathon Schendel SD1230 Module 3 Lab 5.1 ITT-Technical Institute Abstract This paper is my Application Development cycles with both the Waterfall method, and the Prototype Method. I will go over what will happen in both methods, and what I prefer, at the end of the paper. I have decided to develop a game for this paper, so all of my decisions and planning will revolve around the making of a small mobile game application. The Waterfall Method First of all, I need to go over the system and software requirements of my environment. I plan on having this game being able to be used on a LG Tribute Android device, which is this writer’s current phone. So I will have to keep in mind the hardware that this application will run on, which can be found on the device, or the LG manufacturer’s website, and then to run on the android version 4.4.2, which is my phone’s current firmware version. Then, I will need to design the game I would want to make. I would want to make a game about upgrades, where you click a button, and each time you click the button, you get a point. You can get upgrades to get more points per button press, and then even get points without even pressing the button. This type of game is called a Idle game, or incremental game. In this phase, I would design the game. Making the name, developing the GUI, (graphical user interface) designing the upgrades and how the game will progress, find or make sounds to implement into the game to make...

...be in charge of the people, process, and activities to ensure the project is on schedule and within budget. The people responsible for the business side of developing software, to include the project manager, focus on issues concerning profit, marketing, and customer satisfaction. There should also be a development team established to pursue a design, gather requirements, create documentation (e.g., design specifications, installation guide, command reference), as well as test and implement the product (Braude & Bernstein, 2011). When engaging a software project, it is important to remember the most critical resources to a project are the people involved. “It is through their efforts that software is successfully constructed and delivered” (Braude & Bernstein, 2011, p. 6). It is also vital to maintain positive client relationships. Clients and customers are responsible for purchasing the cost-effective, high-quality software that meets their specific requirements. Whether these people are the end-users or not, the user-interface should make duties efficient and be easy to use (Braude & Bernstein, 2011). The Waterfall Model The simplest and most easily implemented development methodology is the waterfall process. The waterfall process begins with the conception of the product and the collection of business objectives followed by the definition and...

...1. Introduction Over the last three years the focus of the information technology industry has moved towards development for the World Wide Web (WWW). Information systems using WWW technology, delivered by an Intranet or via the Internet, are now prevalent throughout New Zealand and overseas. Within New Zealand, a wide variety of organisations are deploying information systems onto the WWW, including banks, government departments and other service providers. They are using the WWW as a strategic business tool, supporting their existing operations or providing a low-cost solution for delivering a new product or service line. 1.1 Proposition and Aims There is an abundance of information on the graphical and user interface aspects of WWW site design. In addition, a large body of knowledge has been developed in the area of software development methodologies. However, there has been very little research conducted to examine if these existing research methodologies are applicable to the information systems developed for the WWW. The WWW is a technologically dynamic environment, and presents new challenges for developers. In order to address the emerging WWW environment, a number of researchers have proposed software development methodologies specifically for the WWW. Consequently, the aim of this research was to investigate how organisations are currently developing WWW-based information systems, and the reasons why those methods are being used. This examination is important...

...Waterfall Methodology Essentially, it's a framework for software development in which development proceeds sequentially through a series of phases. Progress "flows" from one stage to the next, much like the waterfall that gives the model its name. Stages 1.Project Planning 2. Requirement gathering 3.Design 4.Develop 5.Testing 6.Production 7.Support Advantages The waterfall model, as described above, offers numerous advantages for software developers. First, the staged development cycle enforces discipline: every phase has a defined start and end point, and progress can be conclusively identified (through the use of milestones) by both vendor and client. The emphasis on requirements and design before writing a single line of code ensures minimal wastage of time and effort and reduces the risk of schedule slippage, or of customer expectations not being met. Getting the requirements and design out of the way first also improves quality; it's much easier to catch and correct possible flaws at the design stage than at the testing stage, after all the components have been integrated and tracking down specific errors is more complex. Finally, because the first two phases end in the production of a formal specification, the waterfall model can aid efficient knowledge transfer when team members are dispersed in different locations. Criticisms Despite the seemingly obvious advantages, the waterfall model has come in for a fair share of criticism in recent times. The...

From the systems planning and selection process, Bob, Thelma, and the analyst recognize their business system needs improvement. In systems analysis, the analyst examines Hoosier Burger to deduce the system requirements, refine and structure these requirements and come up with alternative design strategies. Next is system design. During this process both logical and physical designs are prepared. In logical design, the analyst concentrates on the business aspects of the company. During the physical design, the logical design is translated into the physical design. Next comes systems implementation and operation. The design now becomes a working...
