=====================1/7====================== Running Head: SYSTEM ANALYSIS AND DESIGN 1 Analyze the New System and Determine the Design Issues with this New System The new touch screen register is present as a business need coming about because of the developing number of clients. This new framework will empower the clerk to be capable procedure exchanges quickly through a mechanized framework utilizing an easy to use contact screen interface. The quick advantage of the new framework is that the clerks will most likely work quicker and clients will never again need to line up before the register. Be that as it may, all together for the framework to work well and addresses client’s issues, the new framework is a plan with strict safety efforts, for example, appointing each clerk an interesting username ID and secret phrase to control openness to the register. Notwithstanding validation control, the register additionally bolts out naturally every following 3 minutes of it not being in utilized and requires a similar clerk to open the register. Notwithstanding, in circumstance where the clerk utilizing the register is experiencing issues signing in or in case where the clerk is missing and did not lockout the earlier day, the chief would require around 3 to 5 minutes to restart the register and open the past client; all together for the new client to almost certainly work the register. Despite the fact that the new framework has great verification measures of control, there are some structural issues with the framework. Configuration Issues with the System The system is planning such that it logs out following three minutes of being idle and just the past client can open it or the supervisor. The time spends in logging back in the framework accordingly implies profitable time in preparing client orders and less says. Another configuration issue with the framework is that it enables the mistaken secret key to enter multiple times and consequently lockout the client with no blunder message.

=====================2/7====================== SYSTEM ANALYSIS AND DESIGN 2 Also, the console format of the register makes it simple for the clerks to enter in the erroneous secret word. The contact screen enables oil to amass on the screen; this makes the screen to be less responsive to the cashiers. Depict How You Would Correct the Design Issues with the System to Make the Restaurant Managers Happy.[2] As an interface fashioner, the main adjustment in the new framework will be to determine the 3 minutes programmed log out of the framework when inert.[2] A remedial measure will be to build the 3 minutes programmed logout to 8 minutes. Expanding the framework programmed logout to 8 minutes will go far to decrease the framework programmed logout amid non-crest business hours. The benefit of expanding the programmed framework logout to 8 minutes

accordingly implies the clerk will have more opportunity to take care of clients; as there will be a decline in time spent in signing in to the register.[5] Another lop-hole associated with this new framework is that when a cashier departs for a break or terminates their shift without logging out of the register, the manager is assigned an additional task to reboot the system.[2] [3] Restarting the system create a downtime of 3 to 5 minutes before the next cashier can log in.[2] A redesign of the new system would be that another cashier can log out the previous user and log in with a different authentication without the manager restarting the system each time a cashier leaf.[2] [3] [1] Another concern with the system is that it causes the clerk to enter the erroneous code is the layout of the button.[8] The system needs to be redesign in a way that a user can operate with electronic authentication card in order to log in;[3] [2] this makes the cashier log in process faster, and the button layout issue, which causes the cashier to wrong key code is resolved.[3] [2] =====================3/7====================== SYSTEM ANALYSIS AND DESIGN 3 Finally, the last design issues of the system that result from building up of lubricate (grease) in the touch screen could be resolved through the covering of the screen with a coat that does not allow lubricate to accumulate. Although the new system presents some usability concerns as identified above, creating a design plan that incorporates security and usability will help in addressing the current problems. Design Plan for the Improve Interface The new improvised touch screen system incorporates better security access control aspect as authorization and authentication, but fail short of integrating security with usability. However, the design issues identified above could be avoided if an approach which is iterative design known as HCI-SEC (Human-Computer Interaction and Security), that allows the simultaneous design of the security measures and user interface during the implementation and design of the new system (Dennis, 2015). In another research in 2005, Flechais pointed out that enhancing the security systems and the user interface is the focal interest of HCI-SEC and went further to recognize the essentials of the user interface in ensuring a secure system usable.[2] [3] The following tasks are needed to enhance the new framework to incorporate usability and security. 1). Employee feedback through questionnaires and data collected from the register on the amount of time the system is log in and out.[3] Collecting data from the system could take a period of 20 days, during which there is the recording of data between peak and non-peak hours of the day.[3] 2). After interpreting data from employee feedback and data collected from the system, the next task will be to designate stuff with access control to all the register.[4] [6] This will reduce administrative bottle-neck as employees will no longer have to linger for the manager to unbolt the register since the designated stuff will always be on the spot. This duty could last for like =====================4/7====================== SYSTEM ANALYSIS AND DESIGN 4 sixteen days because the stuff with access monitor to all the register requires to document changes required for improving and testing the new system. 3). Perform an exploration specifically, a market study on the usage of resources during inventory log in and out. For this task, about ten days can be allocated for research and twelve days to form, test and document any significant changes. After completing this task, the next task is to compare the different button layout. 4). Performa an analysis of button layout and compare with alternative screens.[4] This will enable the redesign time to be able to determine the best button layout of the interface that minimizes entering error. This phase can last for 9 days and 12 days will be used to develop the test and record any changes in the system. 5). Another task will be to add a tariff (menu) bar in the boundary with the option to reset the system in a situation when cashier departs without signing out or forget the access card and the manager is not around. This includes changes in code and hence will take about twenty- four days to form, test and document the change. The next section of the paper address aspects of usability and security and explain confronts of incorporating them. How does the New System Balance Security and Usability and Challenges Encounter in incorporating it into Design?[4] The field of security and usability engineering have gained wide recognition over the past decades, with the first research on HCI dated far back as 1975 focusing on improving the usability of software through a systematic approach to design. This is further supported in another research conducted in 2016 showing that most design effort of any system focuses on the usability of security of the system (Dalton, 2016). This aforementioned research conformed to the new fast-food chain system, whereby most of the design focus on security leaving out a =====================5/7======================

SYSTEM ANALYSIS AND DESIGN 5 certain aspect of usability.[4] This implies that security systems are not well design and users of the system tend to look for alternative ways to use the system (Packard, 2016). The case of the new system incorporates security access control user ID and password- based authentication. This is to ensure that only an authorized cashier can have access register;[0] so as to prevent another cashier from performing an uncontrolled transaction with someone else authentication.[0] [4] The aspect of using user authentication in the system encourage usability as cashier accountability can be trace;[0] even though challenge will be that the users have to memorize their user id and password and also a colleague with malicious intention could as well observe another cashier as he or she enters the user id or password.[0] Another security measure of the system that incorporates usability of the system is the automatic log out of the register after 3 minutes.[1] [0] [2] Even though this security measure is effective since it prevents unauthorized users from accessing the register to perform the false transaction. There is a tradeoff for usability in the system because the cashier needs to log in every 3 minutes when an active session timeout. The suggestion of Changes that Improve Security and Usability of the System The first change in the system that will improve the security and usability of the system is increasing the automatic logout of the register to 8 minutes when inactive.[0] [1] Increasing the automatic logout of the register to 8 minutes will not in any way affect security but would enhance usability enormously.[0] [1] Another improvement of the system would be such that a new user could be able to log out the previous user and login with a different credential without the manager necessarily coming to reboot the system.[1] [0] [2] This measure is effective as there is no tradeoff between security and usability of the system.[0] [1] Since the register will already be log out after 8 minutes making that =====================6/7====================== SYSTEM ANALYSIS AND DESIGN 6 the security of the system is not hampered and the fact that the user can easily log in without having to wait for the manager to restart the register means usability is improved on like the previous system.[1] [0] Lastly replacing the security access control of password authentication with electronic card authentication, does not affect security or usability in any way.[0] [1] Instead, security of the system is enforced since the electronics card authentication is more advanced than password authentication.[0] [1] On the other hand, the introduction of electronic card authentication improve the usability of the system as cashiers will no longer have to memorize password and errors resulting from entering incorrect password are completely eliminated in the system;[1] [0] thus, making the system more user-friendly. =====================7/7====================== SYSTEM ANALYSIS AND DESIGN 7
