PurposeThe management of project scope plays a crucial role in increasing the chances of successful project implementation.The ability to manage scope proficiently is fundamentally connected to the effective handling of complexity. Asproject complexity escalates, the task of managing the project scope becomes increasingly difficult, necessitating thatthe project achieves its intended goals within defined constraints. Ongoing reports of project failures linked to poorscope management practices continue to surface, despite thorough research that has identified and analyzed existingdeficiencies, highlighting the necessity for additional scrutiny.Design/MethodologyThe study adopted descriptive research design. The target population of this study was 4,337 public primary schools’projects under the Digital Literacy Program in the selected Western Kenya Counties. The study took place between2013 and 2019, covering the first phase of the Digital Literacy Program implementation plan. The study used bothprimary and secondary data.FindingsThe study found that scope management is statistically significant in explaining success factors of Digital LiteracyProgram in Western Kenya. Furthermore, the findings indicated that project complexity had a notable moderatingeffect on the relationship between scope management and success factors of the Digital Literacy Programme inWestern Kenya.Practical ImplicationsThe insights derived from the study of project complexity imply that complexity is likely to negatively influence thesuccessful implementation of projects. The relationship between scope management and the success factors of aproject is significantly compromised by the project's complexity. Thus, the execution of project scope managementpractices is vital for the successful realization of projects, underscoring the necessity for their consistent application.Keywords:Project Scope Management, Success Factors of Digital Literacy Programme, Project Complexity
