The Impact of Internal Stakeholder Engagement on Project Performance in East African Organizations: An Empirical Investigation

Considering that East African organizations carry out projects to meet their key goals due to resource and institutional constraints, this paper analyzes to what extent internal stakeholders influence project performance. Leveraging Stakeholder Theory and the Resource Based View, the paper focuses on four key internal variables: top management support, internal communication, employee competence and employee engagement and their direct, mediating, and moderating effects on performance measures, such as on time, on budget, and quality. Even with the improved methodologies in project management, failure rates are still notable in Kenya and Uganda. An astounding 68% of infrastructure projects are found to have cost overruns and 72% of projects suffer failure to meet deadlines. This substantial gap leads me to believe that we need to focus on internal stakeholders rather than external stakeholders, which are often overlooked in transitional economies. For this study, I used a concurrent mixed methods approach and collected data from 250 professionals in the construction, IT, development, and public services through structured surveys with a 5-point Likert scale and 15 semi-structured key informant interviews. I employed Structural equation modeling (SEM) to analyze the quantitative data (model fit: χ²/df = 2.15, CFI = 0.96, RMSEA = 0.07) and used thematic analysis to triangulate the qualitative data. I performed a longitudinal follow up with 180 of the respondents to confirm causality over a period of six months. The influence of internal stakeholders on performance is particularly strong, accounting for 68% of the variance (R² = 0.68). Top management support is identified as the largest contributing factor (β = 0.40, p < 0.001), with internal communications processing 30% of the effect (indirect β = 0.12). Employee competence (β = 0.24) and engagement (β = 0.18) demonstrate moderate direct effects which are impacted by cultural and resource factors. High engagement scenarios are associated with 15-25% greater effect impacts. Among sectors, construction (β = 0.28) demonstrated the highest effect of competence. Qualitative themes, such as "cascading commitment" and "informal networks," illustrate the added value of synergy in the collectivist environment. From a theoretical perspective, this contributes to integrated framework evolution in developing countries. From a practical perspective, this suggests optimizing leadership, communication blend, and training to reduce failures by 20-30%. The provision of incentives to stakeholders whose maturity facilitates the achievement of the SDGs is a policy recommendation. Self-reporting bias is a limitation, and future research should investigate the use of technology.
