Anyone who has delivered a product or service understands the triple constraint. Time, cost and scope have to be controlled to successfully complete a project. However, there’s a fourth constraint that’s less discussed: quality. Cost of quality (COQ) helps you avoid neglecting quality and boost customer satisfaction. How COQ does this, especially in project management, is what we’ll define. But we’ll also discuss the cost of good quality vs. the cost of poor quality and show you how to measure COQ. Whether you’re manufacturing products or delivering a service, project management software can help you with the cost of quality. What Is Cost of Quality (COQ)? The cost of quality is a method by which an organization calculates how much it will cost to deliver a product or service that meets the quality expectation standard set in the project plan. This is a means by which companies can figure out how delivering quality will impact their bottom line. This concept has been around for a long time. The book Quality Control Handbook, published in 1951 and written by quality expert Joseph Juran, defined cost of quality as having both tangible and intangible costs. It’s also part of Lean Six Sigma, a philosophy of improvement built on the prevention of defects over defect detection. COQ takes into account not just the manufacturing of the product or the cost to deliver a service, but the financial impact of having to rework items or scrap a project will cost. It’s also not just forecasting the impact of poor quality but the expense of audits and maintenance that comes with delivering a quality product or service. A benefit of cost of quality is that it gives manufacturers or service providers a chance to analyze their processes and in so doing improve quality operations. This is done in two ways as illustrated above: controlling good quality against the failure of control, which leads to bad quality. To maintain quality in your project, you need to establish procedures and guidelines. Project management software gives you the tools to implement these procedures and track them to ensure quality. ProjectManager is online project management software that allows you to plan, manage and track quality control in real time. Use our robust Gantt charts to create product roadmaps to control quality standards at each step of the development process. Once you set the schedule as your baseline, you’ll be able to monitor the planned effort against your actual effort to stay on track. Get started with ProjectManager today for free. Cost of Quality in Project Management Making sure you deliver quality products or services at the cost you’ve determined in your budget is fundamental to project management. The cost of quality is one method that project managers use to avoid overspending, which negatively impacts stakeholders, team members and customers or end-users. Naturally, not delivering quality in any project is an expensive problem. It’ll leave stakeholders unhappy, but also those who will be using the product or service. Project managers must review the cost of quality in their projects to optimize the amount of investment there needs to be. This doesn’t mean using high-grade materials but avoiding costs related to quality issues. Some of these costs can be the price of materials, which could lead to a better working and longer-lasting product. But COQ is part of every phase of the project’s life cycle. Being able to calculate the cost of quality informs the project manager’s decisions throughout the project. It speaks to the balance of investing in quality during the project with the future costs of not preventing or catching issues during product production. Cost of Good Quality (COGQ) vs. Cost of Poor Quality (COPQ) Cost of quality is broken up into two categories, the cost of good quality and the cost of poor quality. COGQ consists of the cost of quality conformance and the ability of a product or service to meet design qualifications. This includes any associated costs associated with appraisal and prevention. COPQ is the costs associated with producing a poor-quality product or service for stakeholders, customers or end-users. It involves all nonconformance costs, both internal and external to the company. These are incremental costs that a business will incur when it fails to meet the quality requirements of the product or service. The difference between these two terms is that they’re opposites that work together in terms of helping one figure out the dollar amount of creating a quality product or service. They do this by looking at the cost of producing quality and comparing that to the cost of paying for delivering a product or service of poor quality. How to Measure Cost of Quality All of this naturally leads to the question of how to measure the cost of quality. But to do this, we need to dig further into the cost of quality categories. We’ve explored the next level, which is the cost of good quality and the cost of poor quality, but both of those categories can be further boiled down. There are four main types of quality costs. The cost of good quality, as noted above, is made up of appraisal costs and prevention costs, while the cost of poor quality is made up of internal failure costs and external failure costs. Let’s first define these terms. Appraisal Costs The appraisal costs are related to checking the quality of the product or service that you’re delivering. Some examples of appraisal costs include the inspection of the product, testing and other types of review to make sure that quality requirements are being met. This can also be associated with the maintenance of any test equipment, supervision of the inspection staff and inventory that has been damaged or destroyed during the testing process.

There are many examples of this type of cost, from training your team to avoid errors and working more effectively to improve work processes. There are also design costs that can fall into this category, as well as quality audits, process planning and evaluating the quality of your suppliers. Internal Failure Costs Internal failure costs are those result from having to repair or rework a product or service because it didn’t achieve the expected quality standard. Some examples of this include any costs related to repairs made in production, having to buy replacement pieces and the cost of reworking the defective product. There can also be an analysis failure or even having to scrap the product development altogether. External Failure Costs External failure costs are associated with having to replace or refund a product that’s defective or has defective parts. Some examples of this include the costs related to warranties, liability costs and the costs associated with lost customers due to a poor product or service. In the worst-case scenario, this could also be legal costs from customer claims. Now that we’ve defined those terms, let’s look at how to measure the cost of quality. Remember, these calculations differ from one organization to the next. Some businesses calculate the total warranty as a percentage of sales, for example. But that’s more for external failure costs. Using the categories we’ve described above, first, calculate the cost of good quality by adding the preventative costs and appraisal costs (COGO = PC + AC). Then calculate the cost of poor quality by adding the internal failure costs with the external failure costs (COPQ = IFC + EFC). Finally, add those two totals for the cost of quality (COQ = COGQ + COPQ). ProjectManager Helps With Cost of Quality (COQ) Once you’ve made these calculations, you’re in a better position to plan your project with the necessary resources. But you still need a quality assurance plan to make sure you’re meeting those quality expectations. Project management software helps you plan and meet your quality standards. ProjectManager is online project management software that gives you the tools you need to plan, manage and track project quality in real time. Monitor Quality in Real Time In order to meet quality expectations, you need to monitor your processes and track metrics in order to catch issues and address them quickly before they negatively impact the project. Our real-time dashboard automatically collects live project data and displays this data in easy-to-read charts and graphs that show everything from time to cost, the workload to project variance. Unlike lightweight tools, there’s no time-consuming configuration necessary. It’s ready when you are. Manage Quality With Kanban Boards If you do notice a problem, you can identify and mitigate it with our kanban boards. Quality issues can be captured on kanban cards, which include descriptions, priority and tags. The team can even comment and attach files to the cards. The visual workflow of the kanban board allows managers transparency as the card moves through columns. Teams can manage their backlog and collaborate on sprints. Another aspect of quality assurance is stakeholders. They have a vested interest in the project and want to know how things are going. You can keep them updated with our customized reports. Whether it’s a status report, portfolio report or a report on cost or time, you can show them relevant data through reports in multiple formats. Keeping stakeholders happy is a type of quality you can never get enough of. ProjectManager is award-winning software that empowers teams to work more efficiently.

任何交付过产品或服务的人都理解三重约束。为了成功地完成一个项目,必须控制时间、成本和范围。然而,还有第四个较少讨论的约束:质量。质量成本(COQ)帮助您避免忽视质量,提高客户满意度。 COQ如何做到这一点,尤其是在项目管理中,是我们将要定义的。但是我们也将讨论高质量的成本和低质量的成本,并向您展示如何测量COQ。无论你是制造产品还是提供服务,项目管理软件都可以帮助你降低质量成本。 什么是质量成本(COQ)? 质量成本是一种方法,组织通过这种方法计算交付满足项目计划中设定的质量期望标准的产品或服务的成本。这是一种方法,通过这种方法,公司可以弄清楚交付质量将如何影响他们的底线。 这个概念由来已久。质量专家约瑟夫·巨然于1951年出版的《质量控制手册》一书将质量成本定义为有形成本和无形成本。这也是精益六适马的一部分,精益六适马是一种建立在预防缺陷而不是缺陷检测的基础上的改进理念。 COQ不仅考虑产品的制造或提供服务的成本,还考虑返工项目或废弃项目的财务影响。它不仅预测低质量的影响,还预测交付高质量产品或服务所带来的审计和维护费用。 质量成本的一个好处是,它给制造商或服务提供商一个机会来分析他们的过程,并通过这样做来提高质量操作。如上所述,这是通过两种方式实现的:控制好的质量,防止控制失败,控制失败会导致质量下降。 为了保持项目的质量,您需要建立程序和指导方针。项目管理软件为您提供了实施这些程序并跟踪它们以确保质量的工具。 ProjectManager是一款在线项目管理软件,允许您实时计划、管理和跟踪质量控制。使用我们强大的甘特图创建产品路线图,以控制开发过程中每一步的质量标准。一旦你将时间表设定为你的基线,你就能够对照你的实际努力来监控计划的努力,以保持在正轨上。立即免费开始使用ProjectManager。 项目管理中的质量成本 确保以预算中确定的成本交付高质量的产品或服务是项目管理的基础。质量成本是项目经理用来避免超支的一种方法,超支会对利益相关者、团队成员和客户或最终用户产生负面影响。 自然,在任何项目中不交付质量都是一个昂贵的问题。这会让利益相关者不高兴,也会让那些将使用产品或服务的人不高兴。项目经理必须审查项目的质量成本,以优化所需的投资额。 这并不意味着使用高级材料,而是避免与质量问题相关的成本。其中一些成本可能是材料的价格,这可能会导致更好的工作和更持久的产品。但是COQ是项目生命周期每个阶段的一部分。 能够计算质量成本为项目经理在整个项目中的决策提供了信息。它说明了在项目期间投资于质量与在产品生产期间不预防或发现问题的未来成本之间的平衡。 质量好的成本(COGQ)与质量差的成本(COPQ) 质量成本分为两类,质量好的成本和质量差的成本。COGQ包括质量一致性的成本和产品或服务满足设计资格的能力。这包括与评估和预防相关的任何相关费用。 COPQ是为利益相关者、客户或最终用户生产低质量产品或服务的相关成本。它涉及公司内部和外部的所有不符合成本。当企业未能满足产品或服务的质量要求时,这些是企业将产生的增量成本。 这两个术语的区别在于,它们是对立的,在帮助一个人计算出创造高质量产品或服务的金额方面,它们一起工作。他们通过查看生产质量的成本,并将其与交付低质量产品或服务的成本进行比较来做到这一点。 如何计量质量成本 所有这些自然引出了如何衡量质量成本的问题。但要做到这一点,我们需要进一步挖掘质量类别的成本。我们已经探讨了下一个层次,即高质量的成本和低质量的成本,但这两个类别都可以进一步归结。 质量成本主要有四种类型。如上所述,质量好的成本由评估成本和预防成本组成,而质量差的成本由内部失败成本和外部失败成本组成。我们先来定义一下这些术语。 评估成本 评估成本与检查你提供的产品或服务的质量有关。评估成本的一些例子包括产品检验、测试和其他类型的审查,以确保满足质量要求。这也可能与任何测试设备的维护、检查人员的监督以及测试过程中损坏或毁坏的库存有关。 相关:免费产品开发模板 预防费用 预防成本用于防止产品生产中出现任何缺陷。这种成本的例子很多,从培训团队以避免错误,到更有效地改进工作流程。也有设计成本可以属于这一类,以及质量审计,工艺规划和评估供应商的质量。 内部故障成本 内部故障成本是指由于产品或服务没有达到预期的质量标准而不得不维修或返工的成本。这方面的一些例子包括与生产中的维修相关的任何成本、必须购买替换件以及返工有缺陷产品的成本。也可能出现分析失败,甚至不得不完全放弃产品开发。 外部故障成本 外部故障成本与必须更换或退还有缺陷或零件有缺陷的产品有关。这方面的一些例子包括与保修相关的成本、责任成本以及与由于劣质产品或服务而失去客户相关的成本。在最坏的情况下,这也可能是客户索赔的法律费用。 既然我们已经定义了这些术语,让我们看看如何衡量质量成本。请记住,这些计算因组织而异。例如,一些企业将总保修计算为销售额的百分比。但那更多的是外部故障成本。 使用我们上面描述的类别,首先,通过添加预防成本和评估成本(COGO=PC+AC)来计算高质量的成本。然后通过将内部故障成本与外部故障成本相加来计算质量差的成本(COPQ=IFC+EFC)。最后,将这两个质量成本的总和相加(COQ=COGQ+COPQ)。 ProjectManager有助于降低质量成本(COQ) 一旦你做了这些计算,你就能更好地用必要的资源来规划你的项目。但是你仍然需要一个质量保证计划来确保你满足这些质量期望。项目管理软件帮助您规划和满足您的质量标准。ProjectManager是一款在线项目管理软件,为您提供实时计划、管理和跟踪项目质量所需的工具。 实时监控质量 为了满足质量期望,您需要监控您的过程并跟踪度量标准,以便在问题对项目产生负面影响之前发现问题并快速解决它们。我们的实时仪表板自动收集实时项目数据,并以易于阅读的图表和图形显示这些数据,显示从时间到成本、从工作量到项目差异的所有信息。与轻量级工具不同,不需要耗时的配置。当你准备好的时候它就准备好了。 用看板管理质量 如果您确实注意到了问题,您可以使用我们的看板来识别和缓解它。质量问题可以在看板卡上捕获,看板卡包括描述、优先级和标签。团队甚至可以在卡片上添加评论和附加文件。看板的可视化工作流程允许管理人员在卡片通过列时保持透明。团队可以管理他们的待办事项,并在sprints上进行协作。 质量保证的另一个方面是利益相关者。他们在这个项目中有既得利益,想知道事情进展如何。您可以通过我们定制的报告随时更新它们。无论是状态报告、投资组合报告还是成本或时间报告,您都可以通过多种格式的报告向他们展示相关数据。让利益相关者开心是一种你永远也看不够的品质。 ProjectManager是一款屡获殊荣的软件,能够让团队更高效地工作。除了能够保持交付成果的质量之外,我们的任务管理、风险管理和资源管理工具还能让您高效工作,而不会超支或错过截止日期。加入Avis、Nestle和Siemens使用我们软件的团队。立即免费开始使用ProjectManager。
