9、re:http:/ IntegrityCanadian account holders information was accessible, AP, 29 May 2002 A design flaw at a Fidelity Investments online service accessible to 300,000 people allowed Canadian account holders to view other customers account activity. The problem was discovered over the weekend by Ian Al
10、len, a computer studies professor at Algonquin College in Ottawa. Fidelity said it had fixed the problem and was offering customers the option of changing account numbers. http:/ Safety-LondonAmbulanceDispatchingSystemThe full introduction of the computer system effectively did away with the radio a
11、nd telephone calls to stations, with the computer dispatching crews to answer calls. But within hours, during the morning rush, it became obvious to crews and control room staff that calls were going missing in the system; ambulances were arriving late or doubling up on calls. Distraught emergency c
12、allers were also held in a queuing system which failed to put them through for up to 30 minutes. Chris Humphreys, Nupes divisional officer, said that it was hard to verify how many people might have died because of the delays but it could be as many as 20. However, the ambulance service contradicted
13、 claims that one 14-year-old boy had died of an asthma attach after waiting 45 minutes. It said that the call was dealt with in 28 minutes - although the Patients Charter has a target of 14 minutes. A man of 83 was also said to have died before the service reverted to the old system at 2p.m. on Tues
14、day.

EDB Fellesdata itself declines to make any statements in the case pending further contact with their customers, the banks. They are considering lawsuits, but if one of

51、o Software Project Management软件项目管理软件项目管理是对整个软件项目生命周期实施的项目管理。项目管理的发展-1(2) 1917年亨利.甘特发明了著名的甘特图1957年杜邦公司将关键路径法(CPM)应用于设备维修，使维修停工时间由125小时锐减为7小时。1958年在北极星导弹设置中，应用计划评审技术(PERT)将项目任务之间的关系模型化，将设计完成时间缩短了两年。20世纪60年代初华罗庚教授将称为“统筹方法”的技术现在通常称为网络计划技术在中国普及推广20世纪60年代项目管理的应用范围也还只局限于建筑，国防和航天等少数领域如美国的阿波罗登月项目项目管理的发展-2(2
52、)1976年PMI在蒙特利尔会议上开始制定项目管理的标准，形成了项目管理职业雏形。1984年美国项目管理协会推出项目管理知识体系(PMBOK)和基于PMBOK的项目管理专业证书(PMP)两项创新中国项目管理的里程碑工作是华罗庚教授和钱学森教授分别倡导的统筹法和系统工程1980年项目管理作为世行项目运作的基本管理模式开始被引入并应用于中国1991年6月我国正式成立中国项目管理研究委员会什么是项目-1(2) 项目就是在既定资源和要求的约束下，为了创造某一独特的产品或服务，由个人或者组织机构所作的一次性工作任务。该任务是由一组有起止时间的，相互协调的受控活动所组成的特定过程。项目具有以下基本特征：明
53、确的目标独特性临时性制约性需要进行计划，执行和控制等不确定性特定的委托人结果的不可逆性其结果可能是一种期望的产品，也可能是一种所希望得到的服务该产品或服务与所有其他产品或服务的某些方面有显著不同，即每一个项目都是唯一的。每一个项目都有明确的开始和明确的结束。受制于有限的资源。在项目的具体实施中，外部和内部因素总是会发生一些变化，因此项目也会出现不确定性。它既是项目结果的需求者，也是项目实施的资金提供者不论结果如何，项目结束了，结果也就确定了。什么是项目-2(2)各种层次的组织都可以承担项目工作。典型的项目有： 建造大楼，工厂或水库；举办各种类型的活动，如会议，晚宴，庆典等；建立新企业，开发新产
54、品等；演出，拍摄影视剧；规划实施某些活动；解决某个研究课题，开发软件由此可知，软件项目只是项目中的一种 什么是项目管理-1(6)项目管理包括对项目各方面的策划，组织，监测和控制等连续过程的活动，以达到项目目标。美国项目管理学会在项目管理知识指南中对项目管理的定义是：“项目管理就是指把各种系统，方法和人员结合在一起，在规定的时间，预算和质量目标范围内完成项目的各项工作，有效的项目管理是指在规定用来实现具体目标和指标的时间内，对组织机构资源进行计划，引导和控制工作”PMBOK定义了项目管理知识体系的9个知识域项目范围管理ProjectScopeManagement项目时间管理ProjectTime

58、lding SuccessIntroduction to Software Project ManagementIntroduction to Software Project Management什么是项目管理-2(6)项目范围管理l为了实现项目的目标而对项目的工作内容进行控制的管理过程。l这里的范围概念包含两个方面:一个是产品范围，即产品或服务所包含的特征或功能；另一个是项目范围，即为交付具有特征和功能的产品或服务所必须完成的工作l项目范围管理包括： 项目启动，范围定义，范围确认，范围变更控制等。项目时间管理l为确保项目最终按时完成而实施的一系列管理过程。包括具体活动定义，活动顺序安排，时
59、间估计，进度安排及进度控制等工作l合理的安排项目时间项目管理中的一项关键任务。什么是项目管理-3(6)项目成本管理为了保证完成项目的实际成本和费用不超过预算成本和费用而实施的一系列管理过程。包括：资源计划编制，成本估算，成本预算，成本控制，资本预算以及基本财务结算等工作。项目质量管理为了确保项目达到客户所规定的质量要求而实施的一系列管理过程。它包括质量计划编制，质量保证和质量控制等工作人力资源管理为了保证所有项目关系人的能力和积极性都得到最有效地发挥和利用而实施的一系列管理措施。包括：组织规划，岗位设置，团队建设，人员选聘等，并着重于对组内人员的管理，包括冲突的处理，对职员工作动力的促进，高效
60、率的组织结构规划，团队工作和团队形成以及人际关系技巧等工作。项目中，人对项目的成败起着至关重要的作用什么是项目管理-4(6)项目沟通管理为了确保项目信息的合理收集和传输而实施的一系列措施。包括通计划编制，信息分发，绩效报告和管理收尾工作。项目经理最重要的工作之一就是沟通。项目沟通管理是人，意见和信息之间的关键纽带，是成功所必须的。参与项目的每一个人都必须做好以项目“语言”方式传达和接收信息的准备同时还要明白他们以个人身份涉及的信息将如何影响整个项目以下为主要过程的概述：l信息计划编制l信息发布l执行情况汇报l行政收尾 确定项目受益人的信息和沟通需求，如什么人需要什么信息，他们什么时候需要，以及
61、如何将信息提供给他们等及时将所需的信息提供给项目受益人收集并发布执行情况信息，包括现状汇报，进度测量和预测等。产生，收集和发布阶段定型或项目完成的信息。什么是项目管理-5(6)项目风险管理l预测在项目中可能出现的最严重的问题（伤害或损失），以及应采取的必要措施。l风险管理涉及项目可能遇到的各种不确定因素包括风险管理划，风险识别，风险定型分析，风险应对计划编制，风险监控等工作项目合同管理l为了从项目实施组织之外获得所需资源或服务而实施的一系列管理措施，包括采购计划编制，询价计划编制，询价，供方选择，合同管理，合同收尾等工作。采购直接影响项目的成本和利润l项目管理人员应掌握较强的合同管理技巧，如应
62、能理解定价合同相对于“成本附加”合同所隐含的风险；还应了解签约中关键的法律原则等什么是项目管理-6(6)项目综合管理l为确保项目各项工作能够有机地协调和配合而实施的综合性合同全局性的项目管理工作和过程，包括项目计划编制，项目计划实施，综合变更控制等工作。l项目综合管理的关键是在相互冲突的目标或可选择的目标中权衡得失，制定决策。项目管理环境项目和项目管理是在一个远远大于项目本身的环境中执行的，这个环境是项目成功的必要条件而非充分条件。主要包括以下几个方面l项目阶段和项目生命周期l项目干系人l组织的影响l通用管理技能l社会，经济和环境的影响组织在执行项目时通常会将项目分解为几个项目阶段，以便更好的
63、管理和控制指那些积极参与项目工作的个体或组织，或者是那些利益会受到项目的执行或项目成功影响的个体或组织。项目通常是某个组织的组成部分，组织在项目管理系统，文化，财务，组织结构等各方面的成熟度都会对项目产生影响通常管理涉及一个组织在管理中各个方面的问题，如财务，市场，销售，研发，战略，组织，自我管理等几乎所有项目都在一定的社会，经济和环境下进行计划和实施的，项目管理团队必须了解社会经济的现状和发展趋势。Software ProjectGeneralProductSystemSoftwareDevelopmentPlatformsCommercialSoftwareEmbeddedSoftware
