A Replicated Survey of IT Software Project Failures 总被引:1,自引:0,他引:1
Despite various industry reports about the failure rates of software projects, there's still uncertainty about the actual figures. Researchers performed a global Web survey of IT departments in 2005 and 2007. The results suggest that the software crisis is perhaps exaggerated and that most software projects deliver. However, the overall project failure rate, including cancelled and completed but poorly performing projects, remains arguably high for an applied discipline. 相似文献

The IETF is currently working on service differentiation in the Internet. However, in wireless environments where bandwidth is scarce and channel conditions are variable, IP differentiated services are sub-optimal without lower layers’ support.In this paper we present four service differentiation schemes for IEEE 802.11. The first one is based on scaling the contention window according to the priority of each flow or user. For different users with different priorities, the second, the third and the fourth mechanisms assign different minimum contention widow values, different interframe spacings and different maximum frame lengths respectively.We simulate and analyze the performance of each scheme with Transport Control Protocol and User Datagram Protocol flows. 相似文献

如果试图从黑川雅之的设计作品中剥丝抽茧,探寻每个来源。我们必须将他生活中的每个细节放大。在他五十多年的设计生涯里.几乎包纳了跨越时间、空间的一切。我们不确定究竟何时何地,他就会对街边的一个瓷碗或是遥远大陆上的旧石像产生兴趣。他挖掘、探索它们.进而深入思考并得出某个结论。过于严肃的头衔其实并不适台他,因为就是凭着“精气神”与好奇心,以及狂热思考。成就了他今天的伟大。 相似文献

Practical Priorities in System Testing 总被引:1,自引:0,他引:1
During the system test phase, "thorough testing" can pass the limits of practicality. Test case selection, based on simple priority rules, is one solution to the problem of practicality vs. thoroughness. 相似文献

The purpose of this study is to identify the IT governance mechanisms that are used at different levels of IT dependence (defensive or offensive IT modes) and to compare the degree of their use between these IT modes. The results of a survey suggest that the degree of use of IT governance mechanisms varies by IT mode, and it is greater when a firm is in offensive versus defensive IT mode. 相似文献

In the face of multiple challenges and opportunities, in a turbulent business environment, chief executives are seeking to create more flexible and adaptable organizations. Increasingly these are taking the form of networks, with electronic links forwards to customers, backwards to suppliers and sideways to business partners. These networks are becoming global, bringing together all those who wish to contribute a proportion of their time to a particular mission. The staff of the network organization need to be supported by a communications network that is itself flexible and adaptable, and able to facilitate multifunctional, multi-location and multi-national team working. In the main the major constraints concern people, their skills and attitudes, and the management of technology, rather than the technology itself. IT professionals, and particularly IT directors, are sought who are able to facilitate change. IT directors require directional qualities which are distinct from those demanded of managers. They need a broad, strategic awareness and perspective concerning the requirements for responsive organizations, with continuing processes for adaptation and learning to meet the changing needs of customers. 相似文献

IP报文优先级分配的一种方案 总被引:3,自引:1,他引:3
王博文 《计算机工程与应用》2002,38(18):186-187
IP路由器在处理到达的报文时可有多种排队方式犤1,2犦。文章提出的将用户数据报类型及报文长度综合考虑的多级优先多队列方案,可改善该排队系统的平均时延,而保持原有的QoS。文章同时给出方案的报文平均等待时间的绝对与相对的数量分析。对于报文长度与优先级的关系问题,以往典型的提法是“短报文应优先,以免被长报文拖延”犤5犦,这种提法有其片面性。实际上,短报文应优先,以改善排队系统的系统平均时延;而如果按报文长度赋予优先级,短报文优先,则可达到最佳系统平均时延。 相似文献

In this study the planning process is applied to a conflict resolution problem by structuring a well known conflict (the Northern Ireland problem) using the levels of a conceptual hierarchy. The parties to the conflict form the first level, the objectives of these parties form the second level, and possible political solutions to the problem are at the third and final level.This present model is an update of an earlier analysis, carried out in 1976 and 1977, in which it was shown that the outcome which would to the greatest possible extent satisfy the aspirations of all parties would be legislative independence for Northern Ireland. The current analysis takes into account changes which have taken place since the earlier work was performed. It is shown that the most satisfactory outcome is still one of legislative independence. However, the results suggest a short-term compromise solution. An assembly, subordinate to the British government, would also satisfy most of the basic needs of the parties, provided that such an Assembly is given a wide range of powers and a large measure of autonomy.The method used here, the Analytic Hierarchy Technique (Saaty, 1977, 1980), is easy to understand and to use, and provides an efficient method for evaluating possible solutions to a conflict. 相似文献
