Human Factors in the Design of the Input Systems - Assignment Example

?SYSTEMS ANALYSIS AND DESIGN Systems Analysis and Design Affiliation Question No Discuss why human factors should or should not be included into the design of the input systems. Human factors refer to the "human characteristics”. A variety of human factors normally fall into one of three divisions of human personality such as physiological characteristics, physical characteristics and psychological or behavioral individuality. However, these sub-divisions of human factors are not essentially equally limited (Nelson & Associates, 2010). In addition, in order to assess the influence of human factors on design of the input systems, it is believed that these factors are really significant. In this scenario, given below are some of the important aspects which can have a significant influence on the system design: (Kirwan, et al., 1997; Kariuki & Lowe, 2010; HSE, 2011; Carayon & Wood, 2010) Interface design and workplace layout: it ensures a high-quality interface Environmental considerations: this factor involves consideration of illumination noise, thermal, and air conditioning factors Communications aspects: it involves making sure dependable communications Job and team design: making easy regarding high motivation and cooperation Selection, training and procedures: the exact person intended for the job, as well as appropriate training and aids Human error and recovery: checking and correcting or keeping away from the results due to human errors, and making sure the humans are able to detect and correct machine errors/breakdowns Explain why it is or is not important to test the system on users? System Testing on User It is really significant to test the system for users. Additionally, the most significant feature of some testing pays attention on the user experience as well as looks for the pinpoint issues for user interaction with the website. This testing outlines what issues exist, how to enhance and improve user’s level of confidence and utility and encourage return visits and circulation with system capabilities. For the majority powerful systems in the world, as well as for one of the majority strong resources exist on the planet, Google positively has a generic technique. In addition, this is a high-quality instance of tackling system usability from the users’ viewpoint and not from a design point of view. Moreover, Google could surely jazz up their system, however they keep it straightforward for the reason that users achieve utmost usefulness by using it. In this scenario, Google is an excellent instance of a website with an extremely high level functionality, however they uphold a clean and uncluttered appearance, as a result users are not overcrowded by tools as well as apps screaming for user attention (RankPay, 2010; Weakley, 2007; Wong, 2010). Question No 2 2. Explain why it is important to use frames. Frames allow us to place our navigation on each system page of a website without making changes on each page. In fact, if the system navigation is in a different frame, and we alter it, it will alter each page that makes use of that frameset. In addition, frames make an advertisement that is for all time available. Additionally, by placing our ads inside a frame at the peak of the page, we make sure that that ad is noticeable still when the reader scrolls the major content. In other words, frames permit us to "brand" our website. In this scenario, we can place our logo as well as website name in a separated frame to keep that information clear and center. Furthermore, frames cover the URLs. Thus, they are not very safe, however if we want our readers to not be familiar with the URL of our pages routinely, frames are able to hide it. As well, when people bookmark our web pages, the URL is the major web page, rather than a deep link, that a number of websites favor (Kyrnin, 2011; Kyrnin, Why should I use frames rather than CSS or CSS rather than frames?, 2011; Boutell, 2011; HTML Code Tutorial, 2011). Explain data capture and OMR. How is it different from OCR? Scanning paper forms to bring them into the computer in order to change different type of marks in checkboxes, text is visible in printed blocks of system form, and barcodes into system readable text is no more a new idea. In addition, the working of the technology, software, flatbed scanners and OMR application, has been improved considerably with the passage of time. Additionally, the price of the scanners and the PCs require executing OMR software has reduced considerably in that time. However, there are many causes why OMR systems and technology is not commonly implemented to develop a minimal CPOE. The majority important restriction is that there is no instant feedback for the ordering physician. On the other hand, all-electronic system can be designed by means of an incorporated decision support system. Though, in a lot of scenarios these restrictions can be satisfactory, offering the benefit of having the orders automatically entered into the computer system (Bergeron, 2005; Trax UK, 2007). Moreover, OCR (Optical Character Recognition) is a language recognition system. Using this tool, a printed material is scanned with a high resolution scanner as an image, so that some changes could be made in that document. On the other hand, OMR is an Optical Mark Recognition. In addition, the optical marks or marking is presented in a specific way by the user using pen or pencil (Yahoo! Inc., 2011; Imaging-Components, 2011). Question No 3 Discuss systems reengineering and how it is performed. Systems reengineering means noticeably resist change and evolution to convene innovative and continually changing business needs. In addition, systems reengineering is normally considered as one of the significant challenges facing software engineers. Additionally, the issues and difficulties are extensive and seriously influencing almost all the types of businesses, as breakdown to reengineer are able to hinder a business’s attempts to turn out to be competitive; as well as persistent, like there appears no cause to be certain that current innovative systems are not as well tomorrow's legacy systems. Moreover, the systems re-engineering presents an expert solution to frequent systems re-engineering issues, comprising its context, name and advantages and disadvantages (Bahill & Dean, 2009; Heriot-Watt University, 2003). Explain some of the tasks in system maintenance. The fundamental tasks in system maintenance are presented below: (Quirke, 2011; Wiesen & Gale, 2011) Data backup Malware management File system maintenance User data is exclusive to the installation and should not be replaced 'off the peg', and due to this fact it is the fundamental concern of system management. In addition, there is a more exact reporting of data management, safe computing and malware (Quirke, 2011; Wiesen & Gale, 2011). Bibliography Bahill, T., & Dean, F. (2009, January 15).
