COMMONALITIES AND CONTRASTS: AN INVESTIGATION OF ERP USABILITY IN A COMPARATIVE USER STUDY

In recent years, several user studies have examined specific usability problems in the field of Enterprise Resource Planning (ERP). These studies focused on different branches, various usability aspects, and several user groups. In spite of this diversification, some common and essential usability problems have become apparent, which are related to system complexity and difficulties in finding required information. However, these findings are based on the situation in a specific country, a singular ERP system and few data samples. Therefore, this paper aims at complementing the related work by results from a comparative user survey from two different European countries: Germany and Latvia. The survey is based on 184 ERP users from Germany and 24 ERP users from Latvia. The results indicated that both countries have several contrasts, but also diverse commonalities in industry, ERP market and culture. However, users in both countries are very homogenous with regard to the assessment of usability problems in their ERP interfaces. This paper investigates elementary usability problems derived from the related work and examines to which extent they are valid in both countries today. The main hypothesis claims that diverse national characteristics do not necessarily lead to a different assessment of usability problems in ERP systems

Web-based, rapid and contactless management of ambulatory patients for SARS-CoV-2-testing

Abstract Background During the SARS-CoV-2 pandemic a mass casualty incident of ambulatory patients occurred at the COVID-19 rapid response infrastructure (CRRI) facility at the University Hospital of Cologne (UHC). We report the development of a patient-centred mobile-device solution to support efficient management of the facility, triage of patients and rapid delivery of test results. Methods The UHC-Corona Web Tool (CWT) was developed as a web-based software useable on each patient’s smartphone. It provides, among others, a self-reported medical history including type and duration of symptoms and potential risk contacts and links all retrieved information to the digital patient chart via a QR code. It provides scheduling of outpatient appointments and automated transmission of SARS-CoV-2 test results. Results The UHC-CWT was launched on 9 April 2020. It was used by 28,652 patients until 31 August 2020. Of those, 15,245 (53,2%) consulted the CRRI, representing 43,1% of all CRRI patients during the observed period. There were 8304 (29,0%) specifications concerning travel history and 17,145 (59,8%) indications of ≥1 symptom of SARS-CoV-2 infection. The most frequently indicated symptoms were sore throat (60,0%), headache (50,7%), common cold (45,1%) and cough (42,6%) while 11,057 (40,2%) patients did not report any symptoms. After implementation of the UHC-CWT, the amount of patient contacts per physician rose from 38 to 98,7 per day. The personnel for communication of test results were reduced from four on seven days to one on five days. Conclusion The UHC-CWT is an effective digital solution for management of large numbers of outpatients for SARS-CoV-2 testing
