Thomas Stearns must decide whether to continue with planned software development and risk missing the completion deadline on a $20 million project or bite the bullet and make some costly hardware changes that will virtually eliminate the risk of missing the deadline. This introductory decision analysis case: (1) contains a compound (square-circle-square) decision, (2) encourages a discussion of the meaning of probability, and (3) requires the use of sensitivity analysis to handle the unspecified costs of missing the deadline. Excerpt UVA-QA-0350 INTERNATIONAL GUIDANCE AND CONTROLS Time was running out on the $ 20 million CARV (confined aquatic recovery vehicle) project, and Project Manager Thomas Stearns was concerned about maintaining the project's schedule. With 10 months left, considerable portions of the software remained to be developed, and Stearns was by no means certain that all the necessary development work would be completed on time. Software Development Stearns had had his project team working full force in recent months on the software development for CARV's command and guidance system. His headcount (the number of full-time-equivalent workers assigned to the project) had been increased recently, so total development costs were running at $ 300,000 per month, which was 25% over the project's budget. Stearns believed that there was but an 80% chance that the necessary software would be completed in the remaining 10 months. Despite the risk of not maintaining the schedule, he could not increase the headcount on the project or increase the rate of software development in any way. If the software were not completed on time, Stearns was fairly certain that one or two extra months of work would suffice to complete the project. Unfortunately, each month's delay in project completion meant a 2.5% ($ 500,000) reduction in the price of the contract. In addition to this precisely defined cost of not meeting the schedule, a hard‑to‑quantify, but no less significant cost of lost reputation was associated with not completing the project as scheduled. . . .
Thomas Stearns必须决定是继续按计划进行软件开发,冒着错过完成期限的风险,还是咬紧牙关,进行一些昂贵的硬件更改,从而消除错过期限的风险。这个介绍性决策分析案例:(1)包含一个复合(方-圆-方)决策,(2)鼓励对概率含义的讨论,(3)要求使用敏感性分析来处理错过截止日期的未指定成本。价值2000万美元的CARV(限水回收飞行器)项目的时间已经不多了,项目经理Thomas Stearns非常关心项目的进度。在剩下10个月的时间里,软件的相当一部分还有待开发,Stearns并不确定所有必要的开发工作都能按时完成。最近几个月,斯特恩斯已经让他的项目团队在CARV的指挥和制导系统的软件开发上全力以赴。他的员工人数(分配给项目的全职员工的数量)最近有所增加,因此每月的总开发成本为30万美元,超出了项目预算的25%。斯特恩斯认为,在剩下的10个月内完成必要软件的可能性只有80%。尽管有不能维持进度的风险,他不能以任何方式增加项目的人数或增加软件开发的速度。如果软件没有按时完成,Stearns相当肯定,一两个月的额外工作就足够完成这个项目了。不幸的是,项目每延迟一个月就意味着合同价格减少2.5%(50万美元)。除了这个精确定义的不能按时完成的成本之外,一个难以量化的,但同样重要的声誉损失成本与不能如期完成项目. . . .有关

On Writing Teaching Notes Well 论写好教学笔记
Pub Date : 2017-06-01 DOI: 10.2139/ssrn.2975053
Gerry Yemen
What material should be included in a teaching note, the instructional tool that accompanies your business school case study—and makes its use far more likely? All good teaching notes have several characteristics in common. This technical note can help any business school professor, case writer, or collaborator create a teaching note that helps an instructor use your case to its fullest potential. Excerpt UVA-PHA-0062 Rev. May 9, 2014 ON WRITING TEACHING NOTES WELL If you want to stimulate discussion, knowing everything about the subject is only half the battle. Equally important, if not more so, is the need to have organized your thoughts well in advance. A good teaching note helps instructors do exactly that: prepare. It also helps the instructor evaluate the appropriateness of a given case. Every well-written business case study should come with an equally well-written teaching note. Sometimes called an instructor's manual, a teaching note suggests how the case may be used—not the only way, but the way the author planned to use it as he or she wrote it (see Exhibit1 for a template). Indeed, even with a road map, many instructors will choose their own routes. There is some debate about whether the optimal time to write a teaching note is before or after the case is taught. In fact, the most effective teaching notes are written both before and after. A solid teaching plan provides a framework for reviewing the case and determining whether enough information is provided for a good analysis and discussion. This note offers suggestions on when to write each part. . . .
教学笔记是伴随你的商学院案例研究的教学工具,什么材料应该包含在教学笔记中,并使其更有可能被使用?所有好的教学笔记都有几个共同的特点。这个技术笔记可以帮助任何商学院教授、案例作者或合作者创建一个教学笔记,帮助讲师充分利用你的案例。写好教学笔记如果你想激发讨论,了解主题的一切只是成功的一半。同样重要的是,如果不是更重要的话,需要提前组织好你的想法。一份好的教学笔记可以帮助教师做到这一点:做好准备。它还可以帮助教师评估给定案例的适当性。每一个写得很好的商业案例研究都应该有一个同样写得很好的教学笔记。教学笔记有时被称为教师手册,它建议如何使用案例——不是唯一的方法,而是作者在写案例时计划使用案例的方法(见附录1的模板)。事实上,即使有路线图,许多教练也会选择自己的路线。关于写教学笔记的最佳时间是在教学之前还是之后,存在一些争论。事实上,最有效的教学笔记是在课前和课后都写的。一个坚实的教学计划提供了一个框架来回顾案例,并确定是否提供了足够的信息来进行良好的分析和讨论。这个笔记提供了关于何时写每个部分. . . .的建议

Living Lean: David and the Case of the Hoarded House 生活精益:大卫和囤积的房子的情况
Pub Date : 2017-06-01 DOI: 10.2139/ssrn.2974967
E. N. Weiss, R. Goldberg, David A. Dube
This case is part of the "Living Lean" series, which presents accessible, everyday scenarios for a Lean process-improvement journey. In this episode on the 5S method of organizing and sustaining an efficient process, a recently transplanted couple with a garage full of boxes decides to eliminate clutter in their home. Excerpt UVA-OM-1448 Rev. Nov. 4, 2013 living lean: DaVID AND the Case of the Hoarded House David and his wife, Heidi, had lived in their single-family home in a new development for about a year and a half. Both followed hectic schedules: David was a student in an MBA for Executives program and a full-time IT program manager, and Heidi was the executive director of a local performing arts center, which required her to work odd hours. As a result, the two of them had allowed their home to accumulate layer upon layer of stuff in almost every room, closet, and wardrobe of the house. One night in December, David drove home from an evening class as a wintry mix of snow and freezing rain began to accumulate on the street. Their house had an attached garage, but he and his wife typically parked on the street and used the front door, because the garage still held a large number of unpacked boxes from their recent move. The wind had picked up, and David was tired, hungry, and cold, so, feeling ambitious, he decided to test the garage entry to his home. He was not sure whether the batteries in the garage door opener were going to work, but when he pressed the button, the garage door began to lift. He slowly nosed his Accord into the garage, hoping for the best, but there were simply too many boxes. He moved the car to the curb, carefully navigated the sidewalk to the front door, sank into the living room couch, and called his wife at work. . . .
本案例是“生活精益”系列的一部分,该系列为精益过程改进之旅提供了可访问的日常场景。在这一集关于5S方法组织和维持一个高效的过程中,一对最近搬来的夫妇有一个装满箱子的车库,他们决定消除家里的杂乱。精简生活:大卫和他的妻子海蒂在他们新开发的单户住宅里住了大约一年半。两人的日程都很紧凑:大卫是emba课程的学生,也是一名全职IT项目经理,海蒂是当地一家表演艺术中心的执行董事,这要求她在业余时间工作。结果,他们俩让家里几乎每个房间、壁橱和衣柜里都堆满了一层又一层的东西。12月的一个晚上,大卫上完夜校开车回家,街上开始积起了冬雪和冻雨。他们的房子有一个附属车库,但他和妻子通常把车停在街上,从前门走,因为车库里还有很多他们最近搬家时拆过的箱子。风起了,大卫又累又饿又冷,所以,他雄心勃勃地决定测试一下他家的车库入口。他不确定车库门开启器里的电池是否能工作,但当他按下按钮时,车库门开始打开。他慢慢地把雅阁开进车库,希望一切顺利,但箱子实在太多了。他把车开到路边,小心翼翼地穿过人行道来到前门,坐在客厅的沙发上,打电话给他工作的妻子. . . .

Galen Pharmaceutics: The Booklet Label Decision 盖伦制药:小册子标签决策
Pub Date : 2017-06-01 DOI: 10.2139/ssrn.2974965
E. N. Weiss, K. Ribe
A packaging supplier for a pharmaceutical firm proposes an innovative cost-saving measure for the next clinical trial: instead of dozens of custom labels for participating countries, one universal booklet label with a page for each. A senior clinical supplies manager must weigh the proposal before presenting it to the clinical team. Were the efficiency and cost savings worth the hassle? This fictionalized case is designed for a first-year operations module on supply chain management. Excerpt UVA-OM-1446 Aug. 3, 2011 GALEN PHARMACEUTICS: THE BOOKLET LABEL DECISION Once again, Milad King, senior clinical supplies manager at Galen Pharmaceutics Inc. (Galen), reviewed the documents on his desk. It was May 2011, and he had just received a proposal from one of his packaging suppliers for Galen's latest Phase III clinical trial. This proposal was unlike any he had seen in the past in complexity, operational design, and, consequently, cost. The supplier was proposing an innovative way to label the supplies for the trial. Although the new label would cost $ 4.00 more per label, the supplier promised significant operational and manufacturing savings that would more than make up for the cost. King knew the clinical team would want his recommendation at its next bi-weekly meeting—which happened to be the following morning. Galen Pharmaceuticals and the Development of GP-8210 . . .
一家制药公司的包装供应商为下一次临床试验提出了一项节省成本的创新措施:不再为参与试验的国家提供数十个定制标签,而是使用一个通用的小册子标签,每个标签都有一页。高级临床用品经理必须在提交给临床团队之前权衡提案。为了提高效率和节省成本,这些麻烦值得吗?这个虚构的案例是为一年级的供应链管理操作模块设计的。GALEN制药公司(GALEN)的高级临床用品经理Milad King再一次审阅了他办公桌上的文件。那是2011年5月,他刚刚收到他的一家包装供应商的提案,为盖伦最新的三期临床试验做准备。这个方案在复杂性、操作设计以及成本方面都不同于他过去见过的任何方案。供应商提出了一种创新的方法来给试验用品贴上标签。尽管每张新标签的成本将增加4.00美元,但供应商承诺,节省的运营和制造成本将远远超过成本。金知道临床小组会在第二天早上召开的下一个双周会议上听取他的建议。盖伦制药和GP-8210的开发…

While maintaining Lean manufacturing standards, the plant manager for the Clarksburg, Virginia, location of a manufacturer of coated abrasives must evaluate a capital investment of $8 million. The investment would reduce labor needs and provide reduced setups. A discounted cash flow analysis must be performed to analyze the investment. Relevant costs and valuation of production flexibility are key issues.This case is taught jointly in two of Darden's first-year courses, Financial Management and Policies and Operations. Excerpt UVA-OM-1503 Aug. 27, 2013 DAZZ MANUFACTURING COMPANY Dorothy Hoffman, plant manager for the Clarksburg, Virginia, location of DAZZ Manufacturing Company, angrily tossed the monthly shipping report back onto her desk and swore under her breath. The Clarksburg plant had again failed to improve its dismal performance meeting shipping dates. Only 60% of its June shipments had met the well-established four-week service standard of the coated-abrasives industry. Hoffman knew that prompt customer service was necessary to maintain DAZZ's competitive position in the industry, but so far, she had seen little improvement in this aspect of the plant's performance. Hoffman was considering the possibility of replacing some of the plant's equipment and revising the production schedule in hopes of more closely meeting her customer-service targets. An investment of $ 8 million would provide a significant reduction in setup times for a major portion of DAZZ's production process. Hoffman believed in lean thinking, the latest management philosophy, but knew the board of directors would need more than just her faith that the lean investment was worthwhile. What Hoffman needed was hard-number justification. Company Background DAZZ was a leading producer of abrasives, including such products as sandpaper and grinding wheels. Industrial firms were the company's primary market. DAZZ had four manufacturing plants in the midsouthern and southeastern United States. DAZZ's Clarksburg plant produced all the company's coated-abrasive products—a line consisting of approximately 5,000 finished items in numerous grades, shapes, and sizes. The Clarksburg plant had $ 126.5 million in annual sales, giving it an 18% share of the U.S. coated-abrasives market and making DAZZ the third-largest of the four major domestic producers. In recent years, DAZZ had achieved a 28% gross margin and 8% operating margin on sales of its coated-abrasive products. . . .
在维持精益生产标准的同时,位于弗吉尼亚州克拉克斯堡的涂层磨料制造商的工厂经理必须评估800万美元的资本投资。这项投资将减少劳动力需求,减少设备设置。必须进行贴现现金流量分析来分析投资。生产灵活性的相关成本和评估是关键问题。这个案例是达顿商学院一年级的两门课程——财务管理和政策与运营——联合教授的。DAZZ制造公司位于弗吉尼亚州克拉克斯堡的工厂经理多萝西·霍夫曼(Dorothy Hoffman)愤怒地将月度出货报告扔回办公桌上,并轻声咒骂。克拉克斯堡工厂再次未能改善其惨淡的业绩,赶上交货日期。在6月份的出货中,只有60%达到了涂层磨料行业公认的四周服务标准。霍夫曼知道,及时的客户服务对于保持DAZZ在行业中的竞争地位是必要的,但到目前为止,她看到工厂在这方面的表现几乎没有改善。霍夫曼正在考虑更换工厂的一些设备和修改生产计划的可能性,希望能更接近她的客户服务目标。800万美元的投资将大大减少DAZZ生产过程的主要部分的安装时间。霍夫曼相信精益思维,这是最新的管理哲学,但她知道董事会需要的不仅仅是她相信精益投资是值得的。霍夫曼需要的是实实在在的理由。DAZZ是磨料磨具的领先生产商,包括砂纸和砂轮等产品。工业公司是该公司的主要市场。DAZZ在美国中南部和东南部有四家制造厂。DAZZ的Clarksburg工厂生产公司所有的涂层磨料产品,这条生产线由大约5000个不同等级、形状和尺寸的成品组成。Clarksburg工厂的年销售额为1.265亿美元,在美国涂层磨料磨具市场占有18%的份额,使DAZZ成为美国四大磨料磨具生产商中的第三大生产商。近年来,DAZZ的涂层磨料产品销售毛利率达到28%,营业利润率达到8% . . . .
