...comparison Structured Systems Analysis and Design Method (SSADM) • Developed by the UK government in 1982; mandatory use for some Civil Service applications; now mature and widely used • Use supported by many CASE tools (including Select) • Builds on the traditional Systems Development Life Cycle and has clearly defined stages; it thus lends itself to project management techniques • Provides development staff with detailed guidelines, requiring, for example, the completion of pre-printed documents • Data driven ; based on assumption that systems have an underlying data structure that changes little over time – however, later versions of SSADM have placed increasing emphasis on user • Thorough quality assurance: deliverables at every stage reviewed in structured walkthroughs and signed off by users • Separates the logical view of the system from the physical • Provides 3 main views of the system, the Data Flow Diagram, the Entity Relationship Diagram and the Entity Life History, which can be cross-checked one against the other. Rapid Applications Development (RAD) • The name speaks for itself – need for RAD driven by rapidly changing business needs • Can be viewed as an example of the spiral model for systems development. The spiral model acknowledges the stages that form the SDLC but builds into each stage iteration, prototyping and extensive user involvement. • Prototyping may be of whole system or part of the system to tease out particular...

...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...

...INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN, ICED’07 28 - 31 AUGUST 2007, CITÉ DES SCIENCES ET DE L'INDUSTRIE, PARIS, FRANCE AN APPROACH TO INCREMENTAL INNOVATION THEORIES AND ITS METHODS IN INDUSTRIAL PRODUCT DEVELOPMENT Hannu Oja Tampere University of Technology ABSTRACT A quest for powerful tools to support creation of innovative solutions exists in industry. Majority of development efforts aims for incremental development of products, either by means of improved performance in use or during manufacturing process. New concepts or solutions on product’s functionality and behaviour (behaviour meaning how the functionality is delivered, response) are needed to bring benefits. Generic product development theories, models and methods are applicable for new product development, as their approach is linear and founded on functional requirements and means to execute them. However, in industry the product development activities preferably start from existing product or concept with pre-determined goals rather than from scratch. Creativity techniques and multidisciplinary workgroups have been referred in literature as means for creating innovations. However, these methods lack context of technical system and are general in nature and could be used for any problem with assistance of experienced moderator and a group of individuals. These techniques and methods are not included in this study. An approach from retrospective case study is presented. It was found that the mental process...

...Checkpoint: The System Development Life Cycle A system study needs to be performed on an accounting information system. There are four stages of the system development life cycle (SDLC) of a business information system. The cycles are; planning and investigation, analysis, design, and implementation, follow-up and maintenance. A broad view point needs to be used to perform a system study for planning and investigation. A mission, planning goals, and objectives needs to be placed. A team should be set up that will speak with the management continuously. This team can be outside the IT department for that broad view point. Also, management will need to appoint a steering committee to work with the study team. Problems may appear and the study team should do a crucial investigation of the system. Advising the steering committee of the findings will be done. After finding the source the committee will decide what is to be mended. Either, do nothing, do a further investigation, or execute a formal system analysis. The system analysis stage is organized to examine the system in detail. Goals need to be set, such as; general system goals, top management goals, and operating goals. General system objectives show benefits, decisions, access and flexibility to change. Top management goals provide managers with planning data to assist in creating important decisions for the future. Operating management goals provide specific managers with assistance in present decisions. System analysis also accomplishes...

...and from observations of how the current system works and is used. Next this document will describe information-gathering techniques that can be used, as well as systems analysis tools that can and will be used for the project. This document will also identify key factors to ensure that information required for the project is gathered successfully. An explanation of the importance of the project scope, will be given. A description of the areas of project feasibility that will be examined will also be discussed. Information will need to be gathered in two different ways. First information will be gathered from the key stakeholders, such as the President & Ceo- Dr. Michael Riordan, the Chief Operating Officer- Hugh McCauley, the Director of Human Resources- Yvonne McMillan, and the Chief Information Officer- Maria Trinth. These key stakeholders are important because they can explain what the current system is as well as how it is used. The second way is to gather information by observing how each employee uses the current system, notating key elements of the system that is used by all employees. Two techniques that are recommended to be used in the information-gathering process are, one-on-one interviews and/or a facilitated session. When using the one-on-one interview technique, each stakeholder will need to be interviewed to gather information on the current systems and to gather their ideas of how they would like the new system to work. This will also give an idea of what...

...Inventory Management System 1.2 Project Context On March 27, 2007, the friends and neighbors of Alberto Biaño in Cebu City were treated to the first serving of Mr. Biaño's famous pizza. This core group became his first loyal customers, as news spread far and wide of the pizza with the great homemade taste that everyone could afford. Inspired by the resounding success of his initial offering, Alberto Biaño continued to develop his recipes to improve his pizzas' quality and taste until a perfect blend of crispy dough and aromatic sauce was achieved for everyone to enjoy. Another innovation was the concept of the “pizzaderia”, which combined the words “pizza” and “carenderia”, to describe the little streetside eateries where Biaño’’s delicious but affordable pizzas were enjoyed by people from all walks of life. Whether for birthdays, anniversaries, celebrations and get-togethers, everyone wanted to make a Biaño’s pizza part of their special treat. From that little pizzaderia in Mabolo, Mr. Biaño soon branched out to Capitol, Tabunok, USC Main, Mandaue and Mactan, making Biaño's pizza a truly well-loved snack in Cebu. Realizing the potential for such great value in an affordable price, many franchisers from different places all over the country such as Cagayan de Oro, Oroquieta City, Butuan soon became part of the Biaño's Pizzaderia family 1.3 Statement of the Problem As of now, Biano’s Pizzaderia only does their inventory manually, and as manual inventory system goes, everyone...

... The primary role of systems analysts and designers is, of course, to produce a computer system solution to a problem that meets the customer’s requirements. This task can easily be so absorbing in itself that there is seemingly no time left over for thinking about the non-technical issues surrounding the introduction of a new IT system, much less for setting up a people project to address them. So even if the people project is not driven by analysts, designers, or even IT managers, it needs their active support. Many of the tasks carried out by analysts in the early stages of an IT development project have outputs that the people project will need to draw on. For example, the process of creating data models and data flow diagrams may raise questions of data ownership, which need to be fed to the people project to resolve, perhaps through a redefinition of rolesand responsibilities or the introduction of a new procedure. Likewise, if systems analysts have done a detailed assessment of costs and benefits, this will give the people project some idea of the messages they can use to sell the new IT system to users and managers. Analysts can also draw on the people project for valuable help in areas such as human–computer interface design, discussed in Chapter 15. The look and feel of the HCI can be one of the most significant factors in determining a user’s response to a system. The people project can help create the conditions in which HCI design can be done collaboratively...

...Final Briefly describe the six stakeholder groups in information systems. How does the systems analyst fit in? The six stakeholders groups in information system are: 1) External Service Provirder (ESP) – a systems analyst, system designer, or system builder who sells his or her expertise and experience to other businesses to help those businesses purchase, develop, or integrate their information systems solutions; may be affiliated with a consulting or services organization. 2) Project Manager – an experienced professional who accepts responsibility for planning, monitoring, and controlling projects with respect to schedule, budget, deliverables, customer satisfaction, technical standards, and system quality. 3)System owners -Interested not in raw data but in information that adds new business knowledge and helps managers make decisions. Business entities and business rules. Concerned with high-level processes called business functions. Business function – a group of related processes that support the business. Functions can be decomposed into other subfunctions and eventually into processes that do specific tasks. A cross-functional information system – a system that supports relevant business processes from several business functions without regard to traditional organizational boundaries such as divisions, departments, centers, and offices 4)System users - View data as something recorded on forms, stored in file cabinets, recorded in books and spreadsheets, or stored...
