Relationships among interpersonal conflict, requirements uncertainty, and software project performance

Interpersonal conflict and user requirements uncertainty are pervasive phenomena that plague information systems projects. Relevant literature indicates that interpersonal conflicts can negatively affect information system (IS) projects, even after controlling for the effects of conflict management and resolution. However, the negative emotional characteristics of conflict alone have limited explanatory power with regard to IS project success. The purpose of this study is to provide additional insights into this phenomenon by examining the impact on IS project performance made by the interaction between interpersonal conflict and requirement uncertainty (which comprises both diversity and instability). The authors surveyed the top 1600 companies in Taiwan and the results revealed that requirements instability would lead to potential interpersonal conflict and interpersonal conflict was directly associated with requirements diversity which, in turn, was negatively associated with final project performance.     

An extension of the EVM analysis for project monitoring: The Cost Control Index and the Schedule Control Index

In this paper we propose two new metrics that combine Earned Value Management (EVM) and Project Risk Management for project controlling and monitoring. We compare EVM cost and schedule variances with the deviation the project should have under the risk analysis expected conditions.These two indexes allow project managers to analyse whether the project over-runs are within expected variability or there are structural and systemic changes over the project life cycle. The new monitoring indexes we present are the Cost Control Index and the Schedule Control Index.

Rethinking organizational design for managing multiple projects

This paper aims at positioning organizational design as an important phenomenon in the field of project management with a high potential of contributing to organizational theory. While organizational design has been neglected by scholars of management and organizational theory, it has been of great interest to those from the project management field. This incongruence—comprising the focus of this study—calls for new insights on theorization in context. The paper provides a preliminary theoretical framework combining contingency theory, the historical approach and social theory to understand organizational design, both as a thing and as a process. It provides empirical evidence from three case studies in healthcare. Findings confirm the specificity of each design while at the same time adopting a similar temporal pattern. We take this opportunity to highlight the seminal work of Rodney Turner on project-based organization and design.

Future criteria for success of building projects in Malaysia

Several success criteria (SC) and categorization models have been introduced and studied in the previous decades to address the issue of project success. However, most of these models have failed to align success criteria with company's success in the long-term. This paper aims at proposing a framework to categorize project success for building projects in Malaysia from the contractors' perspective. The proposed framework incorporates criteria that align the project efforts with both short and long-term goals of the companies; moreover provide an appropriate judgment of success at all stages of the project. If construction managers can judge the probability of success, they would be able to evaluate the overall relative strength of each project, and identify problems on current projects to direct them toward success.Based on the available literature, thirteen success criteria were found to be significantly and substantially related to building projects success. To develop the SC categorization framework, 151 participants, who are involved in building construction, were invited through a postal and e-mails survey to generate priorities of these criteria. The results of this study indicated that a categorization scheme for success criteria for building projects should include the categories of project management success, product success, along with market success. The findings of this study can further help future researchers seeking solutions in the challenges relating to improvement of building projects implementation and enhancement of project success.     

南水北调西线工程区及邻域的活动构造

南水北调西线一期工程在构造上位于青藏高原东部的巴颜喀拉地块内部,块体的四周边界以巨型走滑断裂和逆断裂为特征,构造运动非常强烈,是块体运动引发应力集中和释放能量的主要场所。但块体内部构造活动性较弱,仅发现甘德—阿坝断裂系北支断裂在阿坝盆地段的部分断裂、色达—洛若断裂和康勒断裂等晚更新世以来有过活动,且规模和运动强度远小于地块边界断裂。晚第四纪以来地块边界断裂的位移速率大多在7 mm/a以上,最大达18 mm/a,最小为1～2 mm/a,而输水隧洞附近最主要的活断层顺河断裂的位移速率仅为0.18 mm/a,相对地块边界断裂小1～2个数量级,可以认为工程场地处于构造相对稳定的地区。给出了阿坝盆地北缘断裂、顺河断裂等活断裂在工程使用期内最大设防的倾滑位移量,分别为0.67和2.62 m。     

南水北调西线一期工程的工程地质和岩石力学问题

南水北调西线一期工程由“四坝、二堰、七洞”组成,年调水量40×108 m3。工程的最大难点在于深埋长隧洞的勘察、设计与施工。工程地质条件相对复杂,枢纽的建坝地质条件较好,块石料满足要求,库区淹没损失小。隧洞区的主要岩石类型为三叠纪的砂岩和板岩,局部出露有灰岩和岩浆岩。深埋长隧洞存在着诸多复杂的工程地质和岩石力学问题,但在目前的经济技术条件下是可以解决的,不存在制约西线工程实施的技术难关和地质条件。     

三峡船闸边坡岩体拉剪试验及强度准则研究

三峡永久船闸边坡开挖后,卸荷和应力重分布使得岩体出现较大范围的拉应力区,且该区岩体多呈拉剪应力状态。为研究受拉区岩体拉剪强度准则,进行了室内岩石拉剪试验,但采用现场试验进行岩体拉剪强度准则研究则较为少见。通过在船闸区开展拉剪面尺寸为50 cm×50 cm的现场岩体拉剪试验,获得了不同拉应力时的岩体拉剪强度,岩体拉剪强度与拉应力关系呈明显的曲线特征。岩体拉剪强度准则研究结果表明:三峡花岗岩岩体拉剪强度准则宜采用莫尔强度准则的二次抛物线型来描述,其次为双曲线型,而双直线型偏差较大。进行边坡变形稳定分析时,对于拉剪应力区岩体则不宜采用直线型强度准则,更不能简单地采用压剪试验取得的直线型关系向拉应力区延伸方法确定岩体拉剪强度。
