Abstract: The aim of this study was to establish the influence of project team diversity on performance \nof rural roads construction projects in Kenya. It also sought to establish the moderating \ninfluence of implementation process of project control systems on the relationship between \nproject team diversity and performance of rural roads construction projects in Kenya. Six \nobjectives were formulated for this study. The study was anchored on ecosystem theory, \nsocial identity theory and organisation control theory. The study applied pragmatism \nparadigm and mixed methods research approaches. Cross sectional descriptive survey and \ncorrelational research designs were adopted. A sample of 361 respondents was selected from \na target population of 3680 construction workers through stratified sampling, simple random \nsampling and purposive sampling techniques. A questionnaire, observation and an interview \nguide instruments were used for collecting data. In this study, data was triangulated through \ncomparison of qualitative data received from structured questionnaires for workers with \nqualitative in-depth interviews for site engineers and observation guide by the researcher. \nQualitative data was analysed through checking data, developing codes, identifying themes \nand patterns and then summarizing the data and linking them to hypothesis and objectives. \nQuantitative data was then analysed and both descriptive and inferential statistics generated. \nDescriptive results were presented as frequency tables, percentages, arithmetic means and \nstandard deviation while inferential statistics were obtained using Pearson’s Product \nMoment correlation (r) and from both simple regression and multiple regression analysis. Ftest \nwas used to test the hypotheses. Tests of statistical assumptions were carried out before \nanalysis. For objective one; r = 0.788, R=0.62, F (4,192) = 285.254, p<0.001˂0.05, \ntherefore, H0 was rejected and concluded that project team demographic diversity \nsignificantly influence performance of rural roads construction projects. For objective two; \nr = 0.804, R=0.647, F (3,193) = 335.874 at p<0.001<0.05, H0 was rejected and concluded \nthat project team training diversity significantly influence performance of rural roads \nconstruction projects. For objective three r= 0.925, R=0.855, F (2,194) = 965.321, at \np<0.001<0.05, therefore, H0 was rejected and concluded that project team experience \ndiversity significantly influence performance of rural roads construction projects. For \nobjective four; r= 0.658, R=0.432, F (3,193) = 136.735 at p<0.001<0.05, therefore, H0 was \nrejected and concluded that project team work-culture diversity significantly influence \nperformance of rural roads construction projects. For objective five; r= 0.939, R=0.882, F \n(4,192) = 358.941 at p<0.001<0.05, therefore, H0 was rejected and concluded that combined \nproject team diversities significantly influence performance of rural roads construction \nprojects. For objective six; R2 = 0.887, ΔR2= 0.005, F (5,191) = 299.871, at p<0.001<0.05, \ntherefore, H0 was rejected and it was concluded that the strength of the relationship between \ncombined project team diversities and performance of rural roads construction projects in \nKenya depends on the implementation process of project control systems. In conclusion, the \nstudy findings provide evidence that for increased performance of rural roads construction \nprojects in Kenya, aspects of project team diversity should be comprehensively addressed. \nIt is therefore recommended that project teams in rural roads construction projects be \nconstituted with an integrated diversity of the workers and that a policy to that effect be \ninstituted and included during professional accreditation criteria for assessing performance \nand awarding of tenders. The findings add to Project Management Body of Knowledge by \nproviding informative insights for project managers and other project management \npractitioners regarding project team diversity and performance of projects. Consequently, a \nsimilar study but with a longitudinal study approach to establish how project team diversity \ninfluences project performance, considering other intervening and contextual factors is \nrecommended.
