摘要

本研究旨在利用部分最小二乘法结构方程模型(PLS-SEM)研究项目管理办公室(PMO)职能对中低收入国家(LMIC)企业项目绩效的影响。这些问题是通过全面的文献综述提出的,涉及 27 个项目管理办公室职能衡量标准(分为 6 组)和 19 个项目绩效衡量标准(分为 6 组)。然后使用 PLS-SEM 对收集的数据进行分析,以验证假设关系。研究结果 PLS-SEM 模型支持调查 PMO 职能与项目绩效之间关系的 36 个假设中的 13 个(t >1.65)。项目管理办公室职能的变化在一定程度上(R2 = 0.34)解释了项目绩效。项目管理办公室的综合活动对环境绩效的影响最大(R2 = 0.467)。项目管理办公室的首要职能是监督和控制项目绩效,它与成本(ß = 0.265,p <0.05)、质量(ß = 0.291,p <0.05)和项目范围(ß = 0.265 p <0.05)绩效显著相关。研究结果表明,如果项目管理办公室的活动能够适应业务环境,就能显著改变项目绩效变量。原创性/价值大多数关于项目管理办公室和项目绩效的研究都局限于发达国家或单一行业。本研究独特地扩展了业务领域,并重点关注低收入和中等收入国家。

Examining the relationship between project management office functions and project performance in Ghana: a structural equation modelling approach

Purpose

The aim of this study is to investigate the influence of Project Management Office (PMO) functions on project performance in businesses in Lower Middle-Income Countries (LMIC) using Partial Least Square–Structural Equation Modelling (PLS–SEM).

Design/methodology/approach

Utilizing close-ended questionnaires in a cross-sectional survey, 256 project professionals from 10 business sectors in Ghana views were elicited. The questions were developed through a comprehensive literature review and involved 27 PMO functional measures grouped into 6 and 19 project performance measures grouped into 6. Data collected was then analysed using the PLS–SEM to validate the hypothetical relationship.

Findings

The PLS–SEM model supported 13 (t > 1.65) out of 36 hypotheses investigating the relationship between PMO functions and project performance. Variations in the PMO functions moderately (R2 = 0.34) explained the performance of projects. The aggregate activities of the PMO had the highest significant influence on environmental performance (R2 = 0.467). The topmost PMO function was identified as monitoring and controlling project performance, and it was significantly associated with cost (ß = 0.265, p < 0.05), quality (ß = 0.291, p < 0.05) and project scope (ß = 0.265 p < 0.05) performance.

Research limitations/implications

This research has brought more illumination to the functions of PMOs and its influence on project performance. The results suggest that PMO activities, when tailored to the business context, can significantly change project performance variables.

Originality/value

Most research on PMO and project performance has been limited to developed countries or a single sector. This study uniquely expands the business sectors and focuses on LMICs.

期刊介绍: ■Organisational design and methods ■Performance management ■Performance measurement tools and techniques ■Process analysis, engineering and re-engineering ■Quality and business excellence management Articles can address these topics theoretically or empirically through either a descriptive or critical approach. The co-Editors support articles that significantly bring new knowledge to the area both for academics and practitioners. The material for publication in IJPPM should be written in a manner which makes it accessible to its entire wide-ranging readership. Submissions of highly technical or mathematically-oriented papers are discouraged.
