摘要

项目绩效是根据成本、时间和质量来评估的。住宅建筑建设项目会遇到各种风险,这些风险会阻碍这些组成部分的性能。风险管理提高了项目绩效,并受到各种因素的影响。本研究确定了风险管理决定因素对肯尼亚内罗毕住宅建筑项目绩效的影响。确定的决定因素是风险缓解战略、风险管理技能、项目组织结构和资源分配。本研究以决策理论、成本效益分析模型和利益相关者理论为基础。目标人群是由NCA 1、2、3类承包商承担的1024个项目。采用分层随机抽样方法,样本量为103个项目(抽样因子为0.1)。采用描述性调查研究设计。试点研究包括5个项目的样本。通过问卷调查收集数据。目标样本的响应率为73.8%,高于预期阈值。数据分析采用SPSS进行推理分析和描述性分析。受访者的教育程度分别为42.11%、36.16%和19.74%,分别为研究生、本科和文凭。50%的受访者工作时间在5-10年之间,36.84%的受访者工作时间超过10年,13.16%的受访者工作时间不足5年。采用Cronbach 's Alpha检验进行信度分析,结果为0.762,表明内部一致性水平较高。模型总结表明R为0.676,表明项目绩效与确定的决定因素之间存在高度相关性。回归分析得到的系数为:Y = 1.779 + 0.258 × 1 - 0.049 × 2 + 0.303 × 3 + 0.120 × 4。说明除项目组织结构外,其他决定因素均与项目绩效呈正相关。研究结果表明,风险管理策略和风险管理技能对肯尼亚内罗毕住宅楼建设项目绩效具有显著的正向影响。建议项目利益相关者一定要采用这些策略。该研究建议在其他领域进行研究,以确定对重要决定因素的比较分析。关键词:风险缓解策略,风险管理,项目组织结构,资源配置Ondara .(2023)。肯尼亚内罗毕县住宅建筑项目的风险管理决定因素和绩效。商业战略杂志;管理学报,2010(2),479 - 495。

RISK MANAGEMENT DETERMINANTS AND PERFORMANCE OF RESIDENTIAL BUILDINGS CONSTRUCTION PROJECTS IN NAIROBI COUNTY, KENYA
Project performance is evaluated based on cost, time, and quality . Residential building construction projects encounter various risks that hamper those components of performance. Risk management enhances project performance and it is affected by various determinants. This study established the impact of risk management determinants on performance of residential buildings construction projects in Nairobi, Kenya. The identified determinants were risk mitigation strategy, risk management skills, project organization structure, and resource allocation. The study was anchored on decision theory, cost-benefit analysis model, and stakeholder theory. The target population was 1024 projects undertaken by contractors in the NCA 1, 2, 3 categories. The applied stratified random sampling method yielded 103 projects as the sample size (sampling factor being 0.1). Descriptive survey research design was used. The pilot study comprised sample of 5 projects. Data was collected using a questionnaire. The response rate from the targeted sample was 73.8% which was above the expected threshold. Data analysis was done on SPSS for both inferential and descriptive analysis. The respondents’ education level was noted to be 42.11%, 36.16%, and 19.74% for post-graduate, undergraduate, and diploma respectively. 50% of the respondents had worked between 5-10 years, 36.84% had worked over 10 years, while 13.16% had worked for less than 5 years. A reliability analysis was conducted using Cronbach’s Alpha test which yielded 0.762, an indication of higher level of internal consistency. The model summary indicated R to be 0.676 which showed high levels of correlation between project performance and the identified determinants. Regression analysis yielded coefficients that resulted in the equation, Y = 1.779 + 0.258X 1 - 0.049X 2 + 0.303X 3 + 0.120X 4 . That illustrated that all determinants had positive correlation with project performance except project organization structure. The study concluded that risk management strategies and risk management skills had positive and significant impact on the project performance of residential buildings’ construction in Nairobi, Kenya. Project stakeholders were recommended to adopt these strategies without fail. The study recommended undertaking the study in other areas to ascertain a comparative analysis on the significant determinants.
