The objective of this study is to determine the impact of change management on digital transformation initiatives in Yemeni telecom sector. A quantitative approach with analytical and deductive methods was adopted to examine the relationship and determine the impact between change management and digital transformation. The study targeted a population of 902 managers and team leaders in the sector. A questionnaire was developed and distributed to a stratified sample of 226 respondents. The random sample was 25% of each stratum. The questionnaire items were designed to measure the change management dimensions (Change Urgency, Visionary Coalition, Empowerment and Sustainability) and digital transformation dimensions (Technology, Processes, People, Culture and Business Model). The results generated show a highly significant positive relationship between effective change management practices and the successful implementation of digital transformation initiatives (substantial positive coefficient B of 0.786, R2 of 0.62 and high t-value of 29.34, and the extremely low p-value below 0.001). In conclusion, this study indicates that digital transformation initiatives require practicing proper and structural change management practices.
