Secondary that allows its students to access all

Secondary Research AssignmentBy Joseph Balich Enterprise Resource Planning (ERP) systems are software packages which present a complete range of database information to users within its respective Information System (IS).  ERPs benefit organizations by yielding benefits such as: “reduced inventory … faster information transactions … better financial management … and increased productivity (Computer Technology Research Corporation, 1999; Davenport, 2000).  Increased use of ERPs over the years have benefitted many organizations while costing others millions of dollars due to failure.  Research has suggested that user satisfaction is the most prominent factor that leads to an ERP’s success; specifically, the perceived usefulness and perceived ease of use of an ERP’s user-interface (Calisir, 2004, p.506).This study was conducted by Fethi Calisir and Ferah Calisir and was titled The relation of interface usability characteristics, perceived usefulness, and perceived ease of use to end-user satisfaction with enterprise resource planning (ERP) systems.  It collected data from 51 end-users from 24 companies in order to determine if perceived usefulness and perceived ease of use affected user satisfaction and which interface characteristics had the largest role in this effect.  Likert-style surveys based on extensive literature review were distributed to companies of different industries that use ERPs.  The questionnaires gathered data on the satisfaction levels regarding the following usability characteristics: system capability, compatibility, flexibility, user guidance, learnability, minimal memory load, perceived ease of use and perceived usefulness.  Statistical analysis determined the data collected to have high levels of reliability and construct validity.  Multiple regression analysis was conducted on the data and indicated that perceived usefulness is the most significant factor to consider when designing for end-user satisfaction in ERP systems.  These findings reinforced previous research which suggested that if end-users believe the system they use increases productivity and performance, they will experience high satisfaction.  The second, smaller, but also significant factor shown to increase end-user satisfaction was learnability.  “The design of a system’s interface should enable easy navigation among different modules” (Calisir, 2004, p. 511).  Design affordances should be built into the system to aid in navigation and prevent disorientation.  Menus should be “broad and shallow” opposed to “narrow and deep” and redundant controls eliminated (Calisir, 2004, p. 511).  Calisir et al. found that an ERP system is less useful to the end-user if the interface is difficult to use, and advises developers to design with this in mind.Group 6 can benefit from the implications of this study because our topic is the Usability of Campus Connect.  Campus Connect is DePaul University’s ERP system that allows its students to access all information that pertains to being a student at DePaul.  This study will prove to be relevant in our solution to enhancing the perceived usefulness, perceived ease of use, and learnability of the Campus Connect user-interface.  Ultimately, in answering the question of “How can we make Campus Connect more usable?”, we can use the research of Calisir and Calisir to shed light on the most important aspects to consider when attempting to enhance end-user satisfaction of this particular ERP system.While perceived usefulness was determined to be the most important factor contributing to end-user satisfaction, I believe that Campus Connect would greatly benefit from enhanced learnability with regards to improving its navigation menus.  Specifically, the implications of using broad and shallow navigation menus versus its current structure which is narrow and deep.  Additionally, our group can consider the various user-interface characteristics included in this study’s questionnaire to formulate other areas of improvement within the Campus Connect system to be considered.BibliographyCalisir, F., & Calisir, F.
