Exploring the Relationship Between Rework Projects and Risk Indicators

When projects fail to adequately meet requirements, organizations are forced to either abandon the project or to initiate a new project to address the original project requirements. Because the organization already has experience with and exposure to many project details, it is possible that the second attempt to address the original requirements (a rework project) will create different challenges for the project team. The purpose of this study was to examine risk indicators for rework projects and to determine whether or not risk indicators were the same or different for rework projects. A risk indicator is a factor that has predictive power about the likelihood of a risk occurring in the course of a project's life cycle. The projects studied for this research were undertaken by a large engineering design organization. The results show that there are some important differences in the types of risk indicators experienced by project managers and project teams in rework projects. Specifically, the risks associated with project urgency, quality, and technological changes were more common in rework projects. By understanding and attending to these differences in rework project risks, project managers will be better equipped to successfully guide rework projects to completion.

Impact of nontechnical leadership practices on it project success

This article examines the leadership practices utilized by information technology (IT) project managers that contribute to project success. Specifically, technical and nontechnical leadership practices are contrasted. The importance of nontechnical leadership practices in IT project management has been largely ignored in research until recently. The article identifies key nontechnical leadership practices that are important for the success of IT projects. The article is based on a qualitative study that gathered data from actual IT projects conducted at U.S. companies across several different industry segments. Study results are analyzed to determine the relevance and value of Heifetz's adaptive leadership framework to the area of IT project management. Study findings indicate that nontechnical leadership practices are important to the success of IT projects. Findings also indicate that Heifetz's adaptive leadership framework is consistent with the key nontechnical leadership practices that are important for the success of IT projects. A framework for the development of IT project managers is also proposed.     

Managing global projects: A structured approach for better performance

The purpose of this research effort is to develop a model for improving the performance of global projects using the underlying relations among the important enablers and barriers of global project performance. A number of factors are identified in the study, using a literature review to develop the model. A survey was used to determine the impact of these factors on global project performance. The model suggests different management practices for global projects versus traditional, co‐located projects. Different from the outcomes of traditional projects, research results suggest that leadership and establishing trust is a first step in the initial stages of the global project.

The selection of supply chain management projects: A case study approach

Organizations undertake strategic supply chain initiatives through project implementation. However, selecting the right supply chain projects can be difficult due to high levels of organizational risk and technical complexity. Although the literature is rich in quantitative and qualitative methods for project management, prior research into best management practices specific to supply chain management (SCM) project selection is limited. This paper examines the methods used in evaluating and selecting SCM projects used by the management at three publically held multi-national organizations. The primary objective of this research is to identify a set of generalizable good practices in the selection and evaluation of SCM projects. Nine useful business practices in SCM project selection have been identified based on cross-case comparisons and a close examination of the literature. Eight practices had been previously identified, but were scattered throughout the literature on ERP, IT management, and R&D management. A new practice calls for the consideration of supply chain partners’ return-on-investment (ROI) in the project selection process. Highest preference should be given to win-win projects for the organization and its partner(s). The practices identified here sho`uld provide the foundation of practical guidelines that can be used during the planning stage of SCM projects. This paper reduces the knowledge gap in SCM project management by analyzing organizations with significant supply chain experience and synthesizing these results with the current related literature.

How Project Manager–Project Owner Interaction Can Work Within and Influence Project Risk Management

Inherent interest conflicts between a project management team and project owner are often neglected in project risk management. Risk management by the project management team basically focuses on project short‐term survival, or project success toward handover to the customer, while for the project owner, strategic success should be more important. To see how this takes place in and influences real projects, seven large projects were studied, and interaction in project risk management between the project owners and project management team was examined for each project. The study revealed that the main focus in the studied projects was on operational risks, even within the project owner's set of high‐priority risks.     

探讨基础设施PPP项目的全生命周期的动态项目管理

当前,PPP模式不仅在我国基础设施建设中发展前景良好,同时在很多国家得到了广泛应用。相比传统的工程项目建设模式,PPP项目具有风险因素复杂和风险较大的特征,因此,PPP项目的成功会在很大程度上受动态项目管理的有效性影响。对项目管理来说,尤其是动态项目风险管理,应贯穿于PPP项目的全生命周期,而只有实现全生命周期的动态风险管理,才能使PPP模式在我国基础设施建设领域中成功利用。
