When managing a project, one is required to make a lot of key decisions. There is always something that needs executing, and often that something is critical to the success of the venture. Because of the high stakes, good managers don’t just make decisions based on gut instinct. They prefer to minimize risk to the best of their ability and act only when there is more certainty than uncertainty. But how can you accomplish that in a world with myriad variables and constantly shifting economics? The answer: consult hard data collected with reporting tools, charts and spreadsheets. You can then use that data to evaluate your decisions with a process called cost benefit analysis (CBA). An intelligent use of cost benefit analysis will help you minimize risks and maximize gains both for your project and your organization. What Is Cost Benefit Analysis? Cost benefit analysis in project management is one more tool in your toolbox. This one has been devised to evaluate the cost versus the benefits in your project proposal. It begins with a list, as so many processes do. There’s a list of every project expense and what the benefits will be after successfully executing the project. From that you can calculate the return on investment (ROI), internal rate of return (IRR), net present value (NPV) and the payback period. The difference between the cost and the benefits will determine whether action is warranted or not. In most cases, if the cost is 50 percent of the benefits and the payback period is not more than a year, then the action is worth taking. The Purpose of Cost Benefit Analysis The purpose of cost benefit analysis in project management is to have a systemic approach to figure out the pluses and minuses of various paths through a project, including transactions, tasks, business requirements and investments. Cost benefit analysis gives you options, and it offers the best approach to achieve your goal while saving on investment. There are two main purposes in using CBA: To determine if the project is sound, justifiable and feasible by figuring out if its benefits outweigh costs. To offer a baseline for comparing projects by determining which project’s benefits are greater than its costs. The Process of Cost Benefit Analysis According to the Economist, CBA has been around for a long time. In 1772, Benjamin Franklin wrote of its use. But the concept of CBA as we know it dates to Jules Dupuit, a French engineer, who outlined the process in an article in 1848. While it’s not clear if this Founding Father followed this exact process, it has evolved to include these 10 steps: What Are the Goals and Objectives of the Project? The first step is perhaps the most important because before you can decide if a project is worth the effort, you need a clear and definite idea of what it is set to accomplish. What Are the Alternatives? Before you can know if the project is right, you need to compare it to other projects and see which is the best path forward. Who Are the Stakeholders? List all stakeholders in the project. What Measurements Are You Using? You need to decide on the metrics you’ll use to measure all costs and benefits. Also, how will you be reporting on those metrics? With ProjectManager.com, you can create eight different project reports with just one click, including project status reports, variance reports and more.Project reporting has never been easier or more accurate—Click to learn more What Is the Outcome of Costs and Benefits? Look over what the costs and benefits of the project are, and map them over a relevant time period. What Is the Common Currency? Take all the costs and benefits you’ve collected, and convert them to the same currency to make an apples-to-apples comparison. What Is the Discount Rate? This will express the amount of interest as a percentage of the balance at the end of a certain period. What Is the Net Present Value of the Project Options? This is a measurement of profit that is calculated by subtracting the present values of cash outflows from the present values of cash inflows over a period of time. What Is the Sensitivity Analysis? This is a study of how the uncertainty in the output can be apportioned to different sources of uncertainty in its inputs. What Do You Do? The final step after collecting all this data is to make the choice that is recommended by the analysis. How to Evaluate the Cost Benefit Analysis The data you collected is used to help you determine whether the project will have a positive or negative consequence. Keep the following things in mind as you’re evaluating that information: What are the effects on users? What are the effects on nonusers? Are there any externality effects? Is there a social benefit? It’s also important to apply all relevant costs and benefits commonly. That is, the time value of the money spent. You can do this by converting future expected costs and benefits into current rates. Naturally, there is risk inherent in any venture, and risk and uncertainty must be considered when evaluating the CBA of a project. You can calculate this with probability theory. Uncertainty is different than risk, but it can be evaluated using a sensitivity analysis to illustrate how results respond to parameter changes. How Accurate is Cost Benefit Analysis? How accurate is CBA? The short answer is it’s as accurate as the data you put into the process. The more accurate your estimates, the more accurate your results. Some inaccuracies are caused by the following: Relying too heavily on data collected from past projects, especially when those projects differ in function, size, etc., to the one you’re working on Using subjective impressions when you’re making your assessment The improper use of heuristics (problem solving employing a practical method that is not guaranteed) to get the cost of intangibles Confirmation bias or only using data that backs up what you want to find Are There Limitations to Cost Benefit Analysis? Cost benefit analysis is best suited to smaller to mid-sized projects that don’t take too long to complete. In these cases, the analysis can lead those involved to make proper decisions. However, large projects that go on for a long time can be problematic in terms of CBA. There are outside factors, such as inflation, interest rates, etc., that impact the accuracy of the analysis. There are other methods that complement CBA in assessing larger projects, such as NPV and IRR. Overall, though, the use of CBA is a crucial step in determining if any project is worth pursuing. Templates to Help With Your Cost Benefit Analysis As you work to calculate the cost benefit analysis of your project, you can get help from some of the free project management templates we offer on our site. We have dozens of free templates that assist every phase of the project cycle. For cost benefit analysis, use there three. RACI Matrix One of the steps when executing a cost-benefit analysis (as detailed above) includes identifying the stakeholders in your project. You need to list those stakeholders, but our free RACI matrix template takes that one step further by outlining who needs to know what. RACI is an acronym for responsible, accountable, consulted and informed. By filling out this template, you’ll organize your team and stakeholders and keep everyone on the same page. Project Budget You can’t do a cost-benefit analysis without outlining all your expenses first. That’s where our free project budget template comes in. It helps you capture all the expenses related to your project from labor costs, consultant fees, the price of raw materials, software licenses and travel. There’s even space to capture other line items, such as telephone charges, rental space, equipment for the office, admin and even insurance. A thorough budget makes for a more accurate cost analysis. Project Risk Register You have your stakeholders identified and your budget outlined, but there’s always the unknown to contend with. You can’t just leave that up to chance: you must manage risk, which is why our free project risk register is so essential. Use it to outline the risks inherent in the project. There are places to list the description of the risk, its impact, the level of risk and who is responsible for it. By maintaining a good risk register you can control the variables in your project and make a better cost benefit analysis.

在进行管理项目时,我们需要做出很多关键的决策。总有一些事情需要执行,而这些事情往往对企业的成功至关重要。优秀的项目经理不会仅仅根据直觉做出决定,因为这样风险很高。他们倾向于尽其所能最大限度地降低风险,并且在有十足的把握之后才会开始实施。 但是,在这个风云变幻,经济因素多变的世界里,怎样才能最大限度的降低风险呢?答案是参考硬数据。这些硬数据是用报表工具,图表和电子表格收集的。然后,您可以使用这些硬数据来评估您的决策,评估过程中会使用到项目成本效益分析(CBA)。正确合理地使用成本效益分析将帮助您把风险降到最低,并且能最大限度地提高项目和公司的收益。 什么是成本效益分析? 项目管理中的成本效益分析是您工具箱中的又一个工具。这个工具是用来评估项目建议书中的成本和收益的。像许多其他的流程一样,成本效益分析也是以从分析列表开始。 每一个项目都有一个列表,列表列出了项目费用以及成功执行项目后的收益。由此列表可以计算投资回报率(ROI),内部回报率(IRR),净现值(NPV)和投资回收期。 成本与收益之间的差额将决定是否有必要实施该行为。在大多数情况下,如果成本是收益的50%,而且回收期不超过一年,那么该行为就是值得实施的。 成本效益分析的目的 在项目管理中进行成本效益分析的目的是要寻找一个系统的方法来计算项目中各种路径的利弊,包括交易,任务,业务需求和投资。成本效益分析为您提供了选择,它提供了实现目标的最佳方法,同时节省了投资。 使用成本效益分析主要有两个目的: 一是通过计算项目的效益是否大于成本来判断项目是否资金充足,项目是否合理和可行。 二是通过确定哪个项目的效益大于成本,为项目之间的比较提供基准。 成本效益分析过程 《经济学人》指出,成本效益分析由来已久。1772年,本杰明·富兰克林(Benjamin Franklin)曾写到了它的用途。但是我们现在知道的成本效益分析的概念要追溯到1848年,当时法国工程师朱尔斯·杜普伊特(Jules Dupuit)在他发表的一篇文章中概述了成本效益分析过程。 虽然尚不清楚朱尔斯·杜普伊特这位创始人是否遵循了这一过程,但成本效益分析演变到如今,主要包括以下10个步骤: 1.项目的目标和目的是什么?第一步也许是最重要的,因为在决定一个项目是否值得之前,你需要清晰而明确的想法。 2.有什么替代方案?在你能够判断这个项目是否可行之前,你需要将它与其他项目进行比较,判断哪一个是最好的。 3.谁是利益相关者?列出项目中的所有的利益相关者。 4.您正在使用哪些度量标准?您需要决定用于衡量所有成本和收益的度量标准。另外,您将如何报告这些指标?有了ProjectManager.com网站,您只需鼠标轻轻一点就可以创建八个不同的项目报告,包括项目状态报告,差异报告等。项目报告从未像现在这样简单或准确-点击以了解更多信息 5.成本和收益的结果是什么?查看项目的成本和收益是什么,并在一个相关的时间段内把他们的对应关系都列出来。 6.什么是通用货币?把你所有成本和收益都换算成同一种的货币,并且做同类比较。 7.折扣率是多少?这将表示某一时期结束时利息金额占余额的百分比。 8.项目期权的净现值是多少?净现值是一种对利润的衡量,指一段时间内现金流入现值与现金流出现值的差额。 9.什么是敏感性分析?敏感性分析是研究 输入的不确定性来源是如何影响输出的不确定性的。 10.你是做什么的?收集所有这些数据后的最后一步就是根据分析做出选择。 如何评价成本效益分析 收集的数据用于帮助您确定项目将产生积极的还是消极的后果。在评估这些信息时,请记住以下几点: 对客户有哪些影响? 对非客户有什么影响? 是否存在外部性效应? 是否有社会效益? 应用所有相关的成本和收益也很重要--即所花金钱的时间价值。您可以通过将未来预期成本和收益转换为现行费率来实现这一点。 当然,任何企业都有其固有的风险,在评估项目的成本效益分析时必须考虑风险和不确定性。你可以用概率论来计算风险和不确定性。不确定性与风险不同,但可以使用敏感性分析来评估不确定性,以说明结果如何响应参数变化。 成本效益分析的准确性如何? 成本效益分析到底有多准确?简单的回答是,它和你在这个过程中输入的数据一样精确。你的估计越准确,你的结果就越准确。 有些时候,导致成本效益分析可能不准确,原因如下: 过于依赖从过去项目收集的数据,特别是当这些项目在功能,规模等方面与您正在处理的项目不同时。 评估时过于主观 不恰当地使用启发式方法来计算无形资产的成本,该方法在解决问题时采用一种不能保证准确性的实用方法。 确认偏差或仅使用备份您要查找的数据 成本效益分析是否有局限性? 成本效益分析最适合于项目周期短的中小型项目。在这些中小型项目中,成本效益分析可以为有关人员作出适当的决定给出参考因素。 但是,项目周期长的大型项目,用成本效益分析可能是有问题的。因为有一些外部因素,如通货膨胀,利率等会影响成本效益分析的准确性。 在评估较大项目时,还有其他一些方法可以作为成本效益分析的补充,如净现值(NPV)和内部回报率(IRR)。不过,总的来说,成本效益分析是决定任何项目是否值得进行的关键一步。 帮助您进行成本效益分析的模板 当您进行项目的成本效益分析时,您可以从我们网站上提供的一些免费项目管理模板中获得帮助。我们有几十个免费的模板,协助项目的各个几段。对于成本效益分析,请使用三个。 RACI矩阵 进行成本效益分析时的一个步骤(如上所述)包括确定项目中的利益相关者。您需要列出这些利益相关者,但是我们的免费RACI矩阵模板做了进一步的工作,即列出了每个人应该知道的事情。RACI是负责任(responsible),问责(accountable),咨询(consulted)和知情(informed)的首字母缩写。通过填写此模板,您可以整理您的团队和利益相关者,并使每个人保持在同一个页上。 项目预算 做成本效益分析之前首先要列出所有费用。我们的免费项目预算模板就是用来做这个的,它帮助您从人工成本,顾问费用,原材料价格,软件许可和差旅中计算到与您项目相关的所有费用。模板甚可以计算其他项目,如电话费,租赁费用,办公室设备费用,行政甚至保险。周密的预算有助于更准确地分析成本。 项目风险登记 尽管你已经确定了利益相关者,并概述了预算,但是总有一些未知的其他问题需要解决。你不能放任不管听天由命:你必须进行风险管理,这就是为什么我们的免费的项目风险登记至关重要。用项目风险登记来概述项目中固有的风险,并在有些地方列出对风险的描述,其影响,风险的级别以及谁对此负责。通过维护良好的风险登记,您可以控制项目中的变量,并进行更好的成本效益分析。 利用ProjectManager.com网站,使任何项目都能盈利 不管你的投资回报在理论计算上有多大,很多价值会随着你的项目执行不力而蒸发。ProjectManager.com是一个屡获殊荣的项目管理软件,它拥有实现项目潜力所需的工具。首先,你需要一个密不透风的计划。 规划 我们的在线甘特图可以对你的项目作出规划并且列出当前的任务,以此来保证最终的项目的成功交付。如果情况发生变化,有时的确会发生变化,甘特图很容易编辑,因此你可以快速调整。 资源管理 另一个阻碍项目的障碍是你的资源。ProjectManager.com提供资源管理工具,可以跟踪您的材料,物资和您最有价值的资源:项目团队。如果他们过度劳累,士气就会下降,生产也会受到影响。 ProjectManager.com上的工作负载页面是用颜色编码的,以显示谁在做什么,并为您提供重新分配的工具,以保持工作负载的平衡和团队的效率。 实时成本跟踪 扼杀任何一个项目的最可靠的方法就是让它掏钱。ProjectManager.com允许您从一开始就为项目设置预算。然后,这个数字会反映在报表和实时仪表板的图表中,这样您就可以随时了解成本是如何影响您的项目的。ProjectManager.com具有引导项目盈利所需的功能。 成本效益分析是一个数据驱动的过程,需要一个足够强大的项目管理软件来消化和分发这些信息。ProjectManager.com是一个基于云的项目管理软件,带有工具,如实时仪表板,可以收集,过滤并以易于理解的图形和图表分享您的结果。今天就用这个免费的30天试用吧。 (此帖更新于2020年10月15号) 创意简报的循序渐进指南 项目资源规划指南 风险登记使用指南
