At the end of week 6, we planned to have completed 55% of the workscope (by effort), i.e. Overview. Earned Value Management Systems Manager 01/2010 to Current Raytheon Space and Airborne Systems – El Segundo, CA. Project Planning. Earned value management (EVM) is a systematic process used to measure project performance at various times throughout a project life cycle. we find our actual expenditure of those same completed activities to be 480 hours. The production of EV data requires that a performance measurement baseline, drawn directly from the project plan, comprising of the following: EV was not developed simply to report status to customers – it may be used in this way, but if this is the only way it is seen, a huge degree of the value of using the method will be lost. Read the article now. Earned value management requires that a … It has the ability to combine measurements of the project management triangle: scope, time, and costs.. Earned Valued Management System (EVMS): This is the collection of tools, templates , processes and procedures that an organization uses to do EVM. Cost. The most important use of this data is by all those in a project team who are responsible for managing work (using EV data via structures such as the work breakdown structure) to understand their cost and schedule performance, throughout the project lifecycle. For more information on project based management and related topics: usually in a Work Breakdown Structure (WBS), APM – the UK’s Association for Project Management, however, on assessing actual progress (using activities completed, known as the 0/100 method) we can calculate that we have only completed activities worth 350 hours of the total task’s budget. EVM was first adopted by the United States Department of Defense in 1967 and today is at the heart of the project control systems, for example, by the governments of the UK, USA and Australia, to help manage the performance of contractors engaged on major development contracts. For more information on the principles of Earned Value Management and how it is applied. The 550 hours can also be translated into cost (£ or $) using average cost rates. Objective Measures of Progress progress must be assessed periodically – there are many ways of doing this and the important rule (backed up by a mass of evidence) is that the more subjective the methods are, the less reliable the EV data is likely to be and the greater room there is for unwanted ‘surprises’ downstream – (we support complete objectivity in progress measurement, and can show that this is possible. Let’s say you are the project manager for the renovation of … Where it is important to have confidence at an early stage that the baseline plan for a project is realistic, an Integrated Baseline Review may be deployed. Earned value management is a project management technique for measuring project performance and progress. The task was baselined at 8 hours, but 11 hours have been spe Earned Value is not just worth it – it is a fundamental tool to being in control in large scale risky development programmes. In this example, our CPI would be (350/480) 0.73 and our SPI would be (350/550) 0.64. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Traditional methods of representing project data (such as simply comparing planned to actual spend) often contain no aspect of performance, which at best can be a significant weakness – at worst it can even be completely misleading. Earned Value Management (EVM) Status Chart – the most common form of graphical output used with EVM. Successfully Presenting Earned Value is a free e-book which will help you learn to implement and present Earned Value schedules. It is very different to simply looking at planned versus actual spend (£ / $) data. In simple terms, Earned Value itself is the contract (or authorised) budget value of work successfully accomplished on a project. For organisations implementing Earned Value Management, the challenge lies not just in the mechanics of the method, but more often in the cultural change required to underpin an EV based project control system. 55% of the total activities within the work package, as the sum of the hours of the activities planned to be completed at the end of week 6 = 550 hours. Email today to find out more on how to conduct a successful Integrated Baseline Review. It is very different to simply looking at planned versus actual spend (£ / $) data. When a piece of work is completed, it is “earned”. Benefits of earned value management. Customers increasingly require contracts to be pro-actively controlled to assure delivery on time, to budget and to specification. In the above chart, the task (or project) is behind schedule and over budget, often expressed as Cost Variance (Earned Value less Actual Cost) and Schedule Variance (Earned Value less Planned Value). hours) required for each. It is a means to provide objective measures of cost and schedule performance throughout a project life-cycle. Additionally, when most organisations first attempt to use EVM, they typically find that it highlights weaknesses or gaps in the project planning and control processes and capabilities. Customers look for confidence in the project status information being supplied, and are increasingly achieving this by defining contractual agreements that require EV to be used by their suppliers. This earned value management example was designed to give a good idea of how to gather the correct information and use it to understand how your project is tracking - as well as what you may need to do to get it back on track. It combines data from scope, schedule and resource measurements to assess project performance and progress. Assuming an organisation follows the principles that underpin good practice in EVM systems, it provides important data to project teams, without which teams can operate in a vacuum regarding their performance, or even worse, they could operate in an environment of false optimism that does not see the level of challenge or issues in their project, until it is too late to make a real impact on the same – something that occurs far too often in projects. Magdalen Centre Earned Value Management 1 Earned Value Management (EVM) is a project management technique that objectively tracks physical accomplishment of work. The rules you use for assigning earned value are highly dependent on how you define your project tasks. Earned value management is mostly used in government projects but can be applied in many projects. Many other methods have been proposed over the years, often being too complex or leading to unreliable EV results). This e-book is offered at no charge. This is what is referred to as planned value or BCWS (at end of week 6). It compares planned work with actual completed work. The principles behind the method represent best pr… This is to inform our understanding of ‘performance‘ against these two primary goals of project management. I believe, Earned Value Analysis(EVA) concept is lot simpler than it is made out to be. It is also widely used in other industries such as Construction, Oil & Gas and others in the UK and elsewhere. Jul 7, 2014. Many practicing professionals find the earned value terms and definitions confusing. So why is much of EVM data expressed using budget values (even schedule data)? Such metrics could be produced across a project, say at work package level. costs) and need to be structurally compatible with the needs of the EVM system. We use cookies to give you the best experience on our website. A simple example of Earned Value Management (EVM) calculations to illustrate the EVM article on Planisware's online Project Portfolio. Let us see a brief introduction of Earned Value Management; Earned Value Management is a technique that helps Project stakeholders to measure project performance. For example: The above question has raged in some environments for many years. Earned value example is based on a simple software development project I explain in a short video. The principles behind the method represent best practice in planning and control in project-based management. Is the project over or under budget? In the past, it has often been mistakenly believed that EV data is only produced for financial reasons or for reporting to customers – this is totally wrong. The best way to look at the earned value calculation is to see an EV calculation example. At the end of week 6 we could perhaps find: In earned value language, this gives us Planned Value of 550 hours, Earned Value of 350 hours, and Actual cost (in hours) of 480. PV or BCWS = Hourly Rate × Total Hours Planned or Scheduled, AC or ACWP = Hourly Rate × Total Hours Spent, EV or BCWP = Baselined Cost × % Complete Actual, EV = baseline of $800 × 91.7% complete = $734, (NOTE % Complete Actual (below) to get the 91.7%), BAC = Baselined Effort − hours × Hourly Rate, % Complete Planned = $800 PV ⁄ $800 BAC = 100%, % Complete Actual = $1100 AC ⁄ $1200 EAC = 91.7%, SV = Earned Value (EV) − Planned Value (PV), SPI = Earned Value (EV) ⁄ Planned Value (PV), CV = Earned Value (EV) − Actual Cost (AC), CPI = Earned Value (EV) ⁄ Actual Cost (AC). and finally, let’s be honest – decades of evidence shows that when allowed to, people will find limitless numbers of ways to manipulate EV results to hide bad news, usually in the mistaken hope of giving themselves time to make the ‘issue’ go away – typically what this does is to reduce the focus, resource and effort on the issue, quite possibly until it becomes irreversible. You are the project manager on a project that has $800,000 software development effort. Earned value analysis uses three key pieces of project information: the planned value, actual cost, and earned value, which are shown in the below diagram. It is used to identify the current condition of the project by tracking all the works that have already been done and forecasting project results based … You are now reviewing the project status and you have ascertained that project is behind schedule. Earned Value data is expressed in budget terms (using the currency of the local environment), which is one of the reasons why it has been misunderstood in the past – it’s not a financial tool, it is a tool for project management. Is the project ahead of or behind schedule? We can also do a number of other things such as calculate cost and schedule performance indices: cost performance index (CPI) and schedule performance index (SPI), where a CPI/SPI of 1.0 equals performance to plan; less than 1.0 is performance less than plan. Actual Costs – Labour and Materials: Actual cost data must then be gathered against by the elements in the PMB – this requires that business systems and processes enable useful and timely capture of actual cost data, via the structures that are employed in the EVM system – not something that falls naturally from all business systems. There are two teams of programmers that … READ MORE on www.slideshare.net. Earned value management systems (EVMS) Earned value analysis (EVA) is a tool that can significant help project. The objective is to embed EV data into the practice of daily management of the project, leading to an improvement in decision-making based upon an informed analysis of real status against cost and schedule goals, at the working levels of the project. This article gives an earned value management example, explains earned value management formulas, analysis, and chart. defining and communicating your EV requirement including the incorporation of the Integrated Baseline Review process, determining appropriate data access and reporting requirements, defining and agreeing on performance review cycles and processes, agreement on the specific objectives of the review and exit criteria, the scope and timing of the review and how it will be conducted. Oxford, OX4 4GA EVM - Examples - To illustrate the concept of EVM and all the formulas, assume a project that has exactly one task. In project management, an earned value analysis serves as an effective tool or material for controlling project cost. The second thing we can do is to use the data to provide a means of forecasting out-turn on projects – the most commonly used being: and for those who dismiss the above, history is littered with projects that displayed (performance) characteristics similar to the above – very very few came in on budget or on schedule (without significantly relaxing the scope of work) – if you know of one please let us know. The following shows the basics of how EV works in practice, using a simple one task example: Imagine we have a work package to design a new widget (made up of a number of activities) with a budget of 1000 hours, having defined all the activities and estimated the effort (i.e. *** N.B. This can also be expressed in other more useful ways, as described in the worked example below. In a single integrated system, earned value management is able to provide accurate forecasts of project performance problems, which is an important contribution for … Ultimately, this will also help in forecasting the project resources to complete the project. Estimate of costs at completion (for the total task: EAC), which for the above example = total budget: 1000 / CPI (.73) = 1,371 hours !! The task would have been completed already. Earned Value Management Formulas with Examples from PMI Measuring earned value management is an excellent way to track the progress of a project. There are hundreds of earned value calculation examples on the internet and in project management books which can be used to get more relevant examples for your industry or type of work - but the general theory and calculations are the same. The purpose of an Integrated Baseline Review (IBR) is to assess a set of EV processes and to confirm the completeness and fitness-for-purpose of the project’s Performance Measurement Baseline. Earned Value Management Technique Formulas and Explanations; Below are some sample PMP questions based on EVM, Q1. The key purpose of earned value management is to inform a project team’s decision making and to highlight cost and schedule issues early, allowing time for recovery action to be taken. The key purpose of earned value management is to inform a project teams decision making and to highlight cost and schedule issues early, allowing time for recovery action to be taken. To illustrate the concept of EVM and all the formulas, assume a project that has exactly one task. We expect the work package to take 12 weeks. The point is that you can do earned value analysis calculations on any project, but unless you have complete earned value management in use on your project, it will be extremely unlikely to obtain correct results. Schedule. They somehow dread formulas and calculations. a robust baseline needs to be developed as soon as possible after contract award – this task alone challenges many organisations – and then it must be maintained, the planning process must identify all major project deliverables clearly, within the PMB, not just the functional effort assumed to be required to deliver a project, objective measures of physical progress must be assessed routinely, business systems and processes need to provide data in a timely manner (e.g. EV gives objective measures of status against the cost and schedule goals of a project – there are no more primary or fundamental goals in project management. As a minimum, the following should be agreed / prepared before the review: IBRs are often preceded by some form of readiness review – given that an IBR should be held as soon as possible and practical following contract award, the scheduling and resourcing of these activities needs to be considered urgently from contract award onward. At the beginning and the end of a project, because of the lack of coordination between crews and equipment, low performance will occur. Earned value analysis is a project management method used to calculate the project status from two perspectives:. England, UK, Tel : +44 (0)1865 784040 A number of things: at its most basic we are behind schedule (earned is less than planned) and we are over budget (actual is greater than earned). As we showed you during the introduction, earned value analysis requires four things to be set up during the project planning phase: Dividing the project into tasks; Assigning each task a start and end date A simple example of Earned Value Management (EVM) calculations to illustrate the EVM article on Planisware's online Project Portfolio Management glossary. Scenario: Supposedly, you are allocated a website project management work with the budget at $200,000. The actual cost of Activity A is ₹ 2,00,000 and that of Activity B is ₹ 1,00,000. documentation and personnel to be made available at the review. Estimate of forecast total duration for the task = current plan: 12 weeks / SPI (.64) = just under 19 weeks (although this is a very rough estimate that should be reviewed against project schedules for work remaining). there are many ways of measuring progress and calculating EV – this is just one example – and a full discussion of this topic itself is outside the scope of a simple worked example (we favour 0/100 over all other methods to assure maximum objectivity) . It’s the main reason for the big focus in the earned value world on the word integration (of cost and schedule data structures etc) – this is critical to making EV work. Fax: 0871 528 3858 (UK only). Earned Value Management Example Problem 3. The Oxford Science Park Earned value management is a method that combines scope, resources, and schedule to asses project progress and performance. The Performance Measurement Baseline (PMB). More elaborately: EVM is used to track the progress and status of a project and forecasts the likely future performance of the project. The PMB consists of a time-phased aggregation of the (human and material) resources (expressed in budgetary terms) required to execute the work scope of the project. The data is converted to a single unit of measure so that planned and ‘actual’ cost and schedule data can be compared literally side by side, for example graphically as below. This Earned Value Management tutorial we analyzed an Earned Value Management Example which emphasizes the benefits of this system in project management. UK MoD Commercial Policy Guideline No.8 – Earned Value Management – Commercial Issues (Nov 2004), US NDIA ANSI 748 – A Standard for Earned Value Management Systems – Intent Guide (Jan 2005). What can we derive from this? You are managing a project which is into six months of its execution. The task was baselined at 8 hours, but 11 hours have been spent and the estimate to complete is 1 additional hour. We do not store or collect any user data. … If you are required to perform an Integrated Baseline Review, it will require preparation and the attention of those who will participate in the review. The aim is to highlight (cost and schedule) issues early, thus providing the maximum time to minimise their impact and provide a realistic opportunity to develop recovery plans where necessary. Assigning Earned Value. EVM integrates the scope, schedule, and cost of a project. Benefits include: 1. Earned Value Management (EVM): This methodology measures project performance with an integrated schedule and budget, which is based on the project work breakdown structure (WBS). It is a means to provide objective measures of cost and schedule performance throughout a project life-cycle.
