Systems Analysis and Design - Essay Example At this stage, the systems engineer is required to ââ¬Å"design the user interface and identify all necessary outputs, inputs and processesâ⬠(Shelly, Cashman and Rosenblatt, 2008, p. 22). In this report, the major information systems techniques and tools will be discussed with special reference to the managerial implications of different CBIS components, techniques and tools. There is special focus on addressing business needs as per the perspective of information systems. Discussion Business Information System Components The main components of an information system are people, data, processes, hardware, software and communications. This holds true for a business information system (BIS) too. People are the element of a CBIS who design, install, communicate, execute processes, and manage the databases. Data can be defined as the information part of CBIS. It is essential for running the software and understanding various organisational issues and scenarios. The element of proce sses is the set of definitions, descriptions, rules and instructions, which guides the people in implementing and operating the CBIS. Further, hardware consists of the computers and their peripherals which are a part of the CBIS. It also includes the networking devices such as switches and routers. Software applications play a functional role in the CBIS. Software is necessary developing and running the system design and running the CBIS. Finally, communication is the component that helps in staffsââ¬â¢ and departmentsââ¬â¢ coordination inside a business house (Stair and Reynolds, 2011) So dividing the BIS (that is, a corporate level CBIS) among the components of people, data, processes, hardware, software and communications is advantageous for a systems engineer to standardise the system design and compare with available paradigms and benchmark. For example, dividing a given information system into standard components helps a systems engineer to organise the different program ming techniques using advanced programming languages like Java and UML (Dennis, Wixom and Tegarden, 2012). Dynamic Diagrams and Rich Pictures Dynamic diagrams are based on isometric projectionsà that help in mapping web sites, developing software programs like MAPA, and publishing certain advanced blogging systems (Kahn, Lenk and Kaczmarek, 2001). Rich Pictures, on the other hand, are a category of diagrams that can help to relate oneââ¬â¢s own experiences and observations to a certain problem situation presented before him/her. This further involves organisation of the development of different business related concepts visibly (Avison, Golder and Shah, 1992). The most important advantage of dynamic diagram is that it helps the user to navigate through the systems. Moreover, it helps the systems designer to detect would-be navigation issues. For example, pictorial representation of the sitemap of a corporate website is helpful for both the customers and systems engineers of the company. Advantage of using rich pictures is that it helps to establish relationships between situations and technologies. For example, user experience with a technology can be described through visible illustrations with the help of rich pictures. Krishnamurti (2011) has used rich pictures to successfully illustrate that how 3D graphics can be applied to enhance construction site management and technology (see Figure
