With the aim of bringing transparency and efficiency to its mining sector, Ethiopia implemented a web based mineral licensing and administration system named FlexiCadastre with the support of the world bank back in 2008. However, the post implementation utilization of the FlexiCadastre is inconsistent between federal and regional mineral licensing bureaus and did not bring the intended business benefit. The strategic direction put forward for the mining sector of Ethiopia in the second growth and transformation plan (GTPII) is attracting foreign direct investment to the mining sector. In an attempt to revive a decline in foreign applicants Ministry of Mines and Petroleum (MoMP) upgraded FlexiCadastre System to Ethiopian National Mining Cadastre System (ENMCS) with an e-government portal to improve the mineral licensing and administrationâ€Ÿs transparency and efficiency which in turn is believed to boost investor confidence. The ENMCS has gone live in December 2019. However, with no empirical study conducted on the post implementation challenges that resulted in the underutilization of the FlexiCadastre and the scarcity of studies on land administration system post implementation critical success factors will makes it difficult to objectively identify factors that will improve the post implementation utilization of the ENMCS. rnThe objective of this study is to identify technical, organizational and operational factors that affect the post implementation utilization of ENMCS and based on the identified issues to propose a high level ENMCS post implementation utilization improvement organizational guide. This research is a case study where a combination of quantitative and qualitative methods has been employed to collect and analyze data. The studyâ€Ÿs research model is proposed after extensive literature review on land administration system (LAS) and ERP post implementation related literatures. The proposed research model that is based on the literature review indicated three major themes; Technical, Organizational and Operational themes that affect the post implementation utilization of the ENMCS. A survey questionnaire that is adopted from literatures and contextualized to the case of ENMCS to quantitatively measure the constructs under the three themes is administered to the population of the study that is 73 federal and regional level ENMCS users. To triangulate the quantitative method findings of the study a qualitative method is applied by administering semi-structured interviews with purposively selected two federal and three regional mineral licensing and administration directors. iv rnDescriptive and inferential analysis has been conducted on the quantitative data of the study using SPSS. The interview findings of the study are arranged into major themes and narrated. The descriptive statistics of the study revealed that 50% of the respondents disagreed on top management having a discussion with them on the impact of ENMCS on their work. The vast majority of survey respondents, 89%, disagreed being made aware of ENMCS upgrades and unavailability through email. The inferential statistics revealed that organizational and operational issues to have a significant positive relationship with the ENMCS perceived usefulness and overall satisfaction of using the ENMCS. The interview findings triangulate the descriptive and inferential statistics findings of the study as they revealed the organizational theme construct of top management commitment having a crosscutting impact on all the constructs of the technical, organizational operational themes. The organizational guide is proposed based on the findings of the study for the constructs that are critical for improving the post implementation utilization of the ENMCS using the people, process and technology concept as a guide.
