In the dynamic and fiercely competitive landscape of Kenya's telecommunications sector, ensuring project success is paramount for achieving financial prosperity. Strategic alignment serves as the cornerstone, orchestrating the harmonious interaction of all organizational facets towards the attainment of strategic objectives. However, despite its recognized significance, empirical evidence suggests a discernible gap between the formulation of strategy and the execution of projects, a misalignment that often precipitates project failures and missed deadlines. With a focus on addressing this critical issue, our study sought to investigate the effect of strategic alignment on project performance within Kenyan telecommunication companies. Employing a desktop research design, we meticulously analyzed existing data and scholarly literature. Our findings underscore a robust positive correlation between strategic alignment and various metrics of project success, including completion rate and schedule adherence. Notably, we observed that project complexity functions as a moderator, emphasizing the heightened significance of strategic alignment particularly in managing intricate projects. In light of these findings, our study advocates for the integration of strategic alignment principles throughout the project management lifecycle. Clear and transparent communication of strategy, coupled with robust mechanisms for aligning project objectives with organizational strategy, emerge as imperative strategies for enhancing project outcomes. By heeding these suggestions, stakeholders stand to capitalize on strategic alignment as a potent lever for driving project success, thereby contributing tangibly to national development objectives and the UN Sustainable Development Goals.
