Nel caso, invece, in cui si trovi un valore negativo, vorrà dire che il progetto è in ritardo rispetto alla pianificazione e sarà necessario assumere dei provvedimenti. CV (Cost Variance): Looking at the project right now, how far under or over budget is it? L’EAC è una valutazione periodica del progetto. Schedule Performance Index (Earned Value Analysis) February 25, 2016 by Bernie Roseke, P.Eng., PMP 2 Comments In project management, getting an early indication of problems is the silver bullet that allows the project manager to correct the problems before they start. Earned Value is not what you will get from the client but is the Value you put in the cost baseline. Questi indici, se applicati ad attività future, consentono al project manager di prevedere come sarà lo sviluppo futuro del progetto, a patto che gli indici di prestazione non fluttuino. Analysis of the collected data reveals the present state of the project. Un’altra analisi che può essere eseguita utilizzando il metodo dell’earned value è quella dell’efficienza di progetto. If you have good systems in place that allow for detailed planning and cost tracking, you might give the method a try. Anche qui il periodo considerato può essere di giorni, settimane, mesi, ecc.

Our Earned Value Analysis Excel Template helps you compare your Planned Value (PV) vs. Earned Value (EV) vs. Actual Cost (AC). They somehow dread formulas and calculations. So you grab a piece of paper to make a few calculations. Lo scostamento dei costi si calcola sottraendo l’earned value dai costi effettivamente sostenuti, utilizzando quindi la seguente formula: CV = EV – AC. SV (Schedule Variance): How far ahead or behind is the project? Il project manager è quindi in grado, utilizzando i progressi misurati, di prevedere il costo totale di un progettoe la data di completamento. Questa tecnica viene utilizzata per evidenziare varianze di costo e di tempo, cioè la cost variance e la schedule variance. Questo valore dà l’idea di come il progetto si sta evolvendo rispetto al budget inizialmente stimato. L’SPI è un indicatore dell’efficienza del programma di un progetto. Inoltre, questa metodologia è un mezzo efficace per proiettare il costo totale di un progetto al suo compimento. We can visualize the metrics in a graph. This is what it looks like: This example will make the concept of earned value clear for you. Ci sembrava però utile semplificare i concetti per rendere più semplice l’approccio a chi voglia sperimentare tale metodo. If you find Earned Value Analysis confusing this is not your fault. Making this calculation allows managers to objectively assess progress and manage resources to complete the project. La pianificazione del progetto è quindi una necessità non solo per poter utilizzare il metodo dell’earned value, ma anche per il successo del progetto in generale. We will now use Earned Value Analysis to answer these questions objectively. In other words: How much money is required to complete the project. Sybase® is a trademark of Sybase Inc. If you’ve never heard about EVA/EVM before, this section might be a bit challenging to understand. Questa cifra indica ciò che si è realmente speso e, come nel caso del valore pianificato, può essere visto in termini di cumulativo e corrente. Il BAC deve sempre essere uguale al PV totale del progetto. If you’re studying for an exam you’ll be able to calculate the EVA metrics without getting stuck. It forecasts the final budget and schedule and analyzes the path to get there. EAC (Estimate at Completion): The amount of money necessary to complete the budget, factoring in money you have spent till now. The most comprehensive trend analysis technique is the Earned Value method. Ma quali sono le cause più frequenti che determinano questi scostamenti? Earned Value cannot be more than Earned Value at any stage. Pick between the options your estimate to your project future condition. Further, analysis of the data trends can forecast the future project performance. 2. You have no way to tell confidently whether your project is doing okay or not. You’ve gotten the latest status of activities and spending, and the overall picture is mixed: Some tasks that should have been done by now are still in progress. L'analisi dell' Earned Value è una tecnica comprovata per misurare con precisione la situazione finanziaria di un progetto. L’earned value è la quantificazione del valore del lavoro effettivamente svolto fino ad una certa data. Il Metodo dell’Earned Value: Cos’è e come usarlo, Come gestire un team di lavoro a distanza. Because a picture is worth a thousand words, let’s look at this graphically. Puoi ben capire quindi quanto possa essetre importante il suo contributo per la gestione del progetto. Earned value analysis assumes you want to see the progress on your project prior to a specific point in time that you choose. Grazie all’EVA, si ha la possibilità di misurare il progetto in base ai progressi raggiunti. Earned value analysis (EVA) appears to be a compelling technique to use on projects to better understand and manage performance. La definizione del budget, la contabilità dei costi, la misurazione dei progressi ed il controllo di gestione. Your actual cost is determined by two factors: First, how much you pay for an activity / deliverable, for example you pay an external engineer $120 per hour. We are going to build a machine for our client — in just 14 days! The Cost Variance is calculated as CV = EV – AC. The SV is calculated as the difference between Earned Value and Planned Value, meaning SV = EV – PV. Earned Value Analysis Exercise www.spmbook.com Author: Adolfo Villafiorita Revision: 2 (2015-02-06) Given the following project plan: IDTask Immediate Predecessor (*) Expected Duration (days) Budget ($) AMeet with client 5 500 BWrite SW A 20 10000 CDebug SW B 5 1500 DPrepare draft manual B 5 1000 EMeet with clients D 5 1000 FTest SW C, E 20 2000 Many practicing professionals find the earned value terms and definitions confusing. Earned Value analysis Il controllo dei costi non è quello di verificare l’importo speso corrente ad una certa data, rispetto a quanto preventivato, ma piuttosto di valutare se quanto speso corrisponde al costo di quanto eseguito realmente (costo earned). L’analisi dello scostamento è un metodo con cui i risultati di un progetto ottenuti sono messi a confronti con i risultati attesi. I created the site to help you bring your projects to success. Rispetto alla schedulazione inizialmente accordata, il progetto potrebbe essere in ritardo, addirittura in anticipo o in linea con la pianificazione iniziale. Most material on EVA/EVM is either vague or doesn’t answer the deeper questions. Ogni livello discendente rappresenta una definizione sempre più dettagliata del lavoro del progetto. Il metodo dell’Earned Value è, nel project management, uno degli strumenti per la gestione del progetto più apprezzati e conosciuti. In particolare è possibile utilizzare lo Scope Statement, la base per eccellenza di un progetto. Imagine you are piloting an airliner from Los Angeles to Hawaii. This method allows the project manager to measure the amount of work actually performed on a project. The Earned Value Method is a useful tool for gauging the performance of your project, but it is difficult to implement. Or you might deliberately postpone an activity, swap or skip activities or you might start working on some task before its originally scheduled start date. It states the sequence of activities and contains deadlines for every task and deliverable. In other words: How much money the entire project is going to cost in the end. E’ fondamentale comprendere come questo indicatore non fornisce dati sull’impatto che un eventuale ritardo del lavoro ha sul progetto e sui suoi risultati. In particolare, esistono due tipi di analisi di efficienza: l’indice di efficienza della schedulazione o Schedule Performance Index (SPI) e l’indice di efficienza dei costi o Cost Performance Index (CPI). You also have a planned schedule: That’s your agreed project schedule. Here's how to do it, How to Track Project Expenses: A Guide For The Diligent. Spesso il termine “earned value” è definito com… Il CPI è invece l’indicatore di efficienza economica di un progetto ed è il rapporto tra earned value (EV) e costi effettivi (CA): CPI = EV/AC. Informix® is a registerd trademark owned by IBM (International Business Machines Corporation) Stabilite le basi, vediamo ora le tre informazioni necessarie per calcolare l’EVA. Example: Imagine a project consisting of 3 activities. Now that you know you are safe, you lean back in your seat and start dreaming about the waves in Waikiki Beach. It has the ability to combine measurements of the project management triangle: scope, time, and costs. La stima al completamento (EAC) è il costo totale previsto per un’attività schedulata. Vedrete significati di Earned Value Analysis in molte altre lingue come arabo, danese, olandese, hindi, … All material on this website is Copyright ©2018, Open Lab S.r.l. Queste stime ci permetteranno di determinare quando il progetto sarà completato e quanto costerà completarlo. Affinché l’analisi dell’earned value sia accurata, è necessario creare un piano di progetto solido.

I believe, Earned Value Analysis (EVA) concept is lot simpler than it is made out to be. Earned value analysis is the project management tool that is used to measure project progress. The Earned Value Method method is also known as Earned Value Analysis (EVA). So I decided to write this article for you to explain EVA in every detail. Fornisce, inoltre, informazioni su come il progetto si sta muovendo in relazione alla sua pianificazione originale. How to use Earned Value Management Calculator. Il valore pianificato descrive fino a che punto, il lavoro riguardante il progetto, dovrebbe trovarsi in un determinato punto della schedule di progetto e della stima dei costi. If you’re studying for an exam you’ll be able to calculate the EVA metrics without getting stuck. The value of these tasks in original valuation amounts to $X in planned value”. SPI (Schedule Performance Index): How far ahead or behind schedule is the project, expressed as a ratio of the overall project duration. The incurred cost is the money we have spent for each task until now. Earned Value shows how much of the budget and time should have been spent, considering the amount of work done so far. Il costo effettivo (AC), anche chiamato costo effettivo del lavoro eseguito (ACWP), è invece il costo effettivamente sostenuto per l’esecuzione di un lavoro per un progetto. FrontBase” is a trademark of FrontBase, Inc BAC (Budget at Completion): The total approved budget. TCPI (To-Complete Performance Index): The Cost Performance Index (CPI) describes the level of performance that must be achieved for the remainder of the project duration so the project will complete on budget. In this earned value management tutorial, we will analyze an Earned Value Management Example.

In questo caso è quindi necessario prendere dei provvedimenti. Improve your project management skills through our weekly tips. To do that, we will first learn how to calculate the earned value of a project. CPI (Cost Performance Index): How far above or below schedule the project is in comparison with the total approved project budget. Richiede molta disciplina ed informazioni dettagliate per essere gestito correttamente. Input the value of your project Planned Value, Earned Value, Actual Cost and Budget at Completion to the respective input fields. 4. È, di fatto, il rapporto tra l’earned value (EV) ed il valore pianificato (PV): SPI = EV / PV. It compares the actual work completed at any time to the original budget and schedule. L’analisi dello scostamento, in caso di mancato raggiungimento degli obiettivi prefissati, serve per capire l’entità della differenza fra i risultati attesi e quelli effettivamente raggiunti. Se stai visitando la nostra versione inglese e vuoi vedere le definizioni di Earned Value Analysis in altre lingue, fai clic sul menu della lingua in basso a destra. Il project manager è quindi in grado, utilizzando i progressi misurati, di prevedere il costo totale di un progetto e la data di completamento. Earned Value Management measures progress against a baseline. Earned Value Analysis commonly referred to as EVA is a technique used for work schedule control and project cost control. method that allows the project manager to measure the amount of work actually performed on a project beyond the basic review of cost and schedule reports For you as the project manager, Earned Value Analysis has the following advantages: Earned Value Analysis gives you a realistic picture of the project status Earned Value Analysis helps you predict any budget gaps and schedule issues The EVM works only when certain requirements are met, and these requirements are quite high. It involves calculating three key values for each activity in the WBS: 1. Thanks to the EVA, it is possible to measure the project according to the progress achieved. Some tasks may get delayed. Project 2016 Tutorial Using Earned Value Analysis Microsoft Training - YouTube. One task was started earlier, because a predecessor was already finished. EV(Planned) = POC (Planned) * C(total) EV(Actual) = POC(Actual) * C(total) In the following paragraphs, actual POC … Oracle® is a registered trademark of Oracle Corporation. Earned value analysis is a project evaluation tool that allows an organization to evaluate the money spent on a project, the amount of work put into the project and the value of the completed work. Se questi due valori non corrispondono, i calcoli e le analisi legate all’earned value saranno imprecise. La WBS suddivide tutti gli ambiti di lavoro in elementi appropriati per la pianificazione. 25% of the distance (= 675 miles) into the trip, you want to know whether you are burning fuel efficiently and if you are going to make it to Daniel K. Inouye International Airport. Earned Value Analysis or Earned Value Management is considered to be one of the more difficult concepts of Project Management. Making an internal audit SWOT analysis, an earned value analysis, or other kinds and types of analyses come with their own challenges, threats, and risks.However, you should not forget the opportunities that you can take so you can further develop the document that you plan to make. Questo valore rappresenta la Schedule Variance (SV). il budget del lavoro pianificato (planned value – PV); il valore effettivo del lavoro completato (actual value – AV); l’earned value del lavoro concreto completato. Key performance indicators (KPI) delineate the current schedule and cost situation. Calculation of the Earned Value. 2. Using the base C(total), for example the planned costs, the system calculates the planned and actual earned value (EV) from the POC. Se l’SPI risulta uguale o maggiore di uno, questo indica una condizione favorevole. MySQL is © 1995- 2014 MySQL AB under the free software/open source GNU General Public License (GPL). EVM requires detailed-level planning and precise cost tracking: Every invoice, every cost item and every hour spent must be assigned to the right cost object. Il PV cumulativo è la somma del budget approvato per le attività pianificate da eseguire in generale. It takes into consideration the work that has been accomplished so far and costs incurred until now, and puts that into perspective to the original budget and schedule (also known as baseline). In un unico sistema integrato, il metodo dell’earned value è in grado di fornire previsioni accurate sui problemi di performance del progetto. The planned budget isn’t just estimated as one large figure, but it’s calculated by estimating the effort and cost for every deliverable and activity in the project, and then summing up the values. Earned value management is a project management technique for measuring project performance and progress. Il metodo dell’earned value, letteralmente “lavoro realizzato“, è conosciuto anche come Earned Value Analysis (EVA). Esaminiamo quindi la stima al completamento (EAC Estimate At Completion) e il bilancio al completamento (BAC Budget At Completion). You always start with a planned budget. CPI = EV / AC. FREE Course! Una WBS documenta la gerarchia e la descrizione dei compiti da eseguire e la relazione di questi con il prodotto finale. If you are below budget, this could mean two things: If you are above budget, this could either mean: Earned Value Analysis can answer this question for you. Se il valore è positivo, significa che il progetto è in anticipo rispetto a quanto programmato. Project managers are then told to start using earned value, with the management expectation that project results will soon improve. (assuming that for every mile flown, you are consuming about the same amount of fuel). ETC (Estimate to Complete): The amount of money necessary to complete the project, not considering money spent until now. L’efficienza di un progetto si può ottenere grazie alle seguenti condizioni: Al contrario, le possibili cause che portano ad un’inefficienza del progetto potrebbero essere: Non parliamo di magia ma di cosa ci si aspetta che accada in un progetto, date le misurazioni dei progressi registrate fino al momento in cui effettuiamo l’analisi. Earned Value Analysis In Project Management Earned Value Analysis (EVA) in project management is an analytical tool that uses data generated during the course of project execution. Unless your entire environment — including your planning and budgeting systems as well as your tracking process — is designed with the intention of conducting earned value analysis, you have no chance of harvesting the benefits of EVM. You have completed activities 1 and 2 so far. How to use multinational calendars in Microsoft Project, Working with Part-time Resources in Microsoft Project, The ultimate guide to managing international projects, How to set up a 7 day work week in Microsoft Project, How to show task numbers in Microsoft Project, Completed work was carried out at a lower cost, Some tasks are delayed and the corresponding costs haven’t hit your budget yet (learn, Some of the work has been more expensive to do, or, Some tasks were started before their scheduled time, and the corresponding costs hit the budget earlier, Earned Value Analysis gives you a realistic picture of the project status, Earned Value Analysis helps you predict any budget gaps and schedule issues. The result: You’ve flown 28% of the total distance, but you have used only 25% of the fuel. Here’s the official definition from the PMBOK Guide: “Planned Value (PV) is the authorized budget assigned to work to be accomplished for an activity or WBS component.”. PostgreSQL is copyright © 1996-2002 by The PostgreSQL Global Development Group Looking to make a project budget in pivot form? In simple terms: EV is the money you should have spent for the work that was actually done.

Grazie all’EVA, si ha la possibilità di misurare il progetto in base ai progressi raggiunti. This means you are well on your way! But don’t worry. With the EVA, the planned and current costs of a project are identified on any desired reporting date, as well as the earned value, as well as other figures like time and cost efficiency. Earned Value (EV): Earned Value (EV) is the value of the work that has been effectively completed so far, using your initial cost estimations as valuation factor and not the actual cost. Hai mai avuto modo di mettere in pratica il metodo dell’earned value in un tuo progetto? If you change the sequence of tasks, this has an influence on your actual cost. We’ll get to the metrics later, but important to remember for now is that among other values, EVA (or EVM) gives you two important key figures: For you as the project manager, Earned Value Analysis has the following advantages: The method gives you a number of metrics, each of which tells you something specific about your project. I requisiti per l’analisi dell’earned value, I concetti fondamentali dell’Earned Value, Come Applicare il metodo kanban al project management, Il digital project manager: quando il Project incontra il web. La WBS è un vero e proprio elenco di tutte le attività di progetto, una scomposizione gerarchica orientata al deliverable del progetto. To understand EVA, you need to understand the concept of planned versus actual numbers with respect to cost and schedule. Observe that the variance and performance index computation results is available instantly. Parte 1 1 Earned value management (EVM) and earned value project/performance management (EVPM) are synonymous terms for EVA. Then the Earned Value for the project at the current point in time is $2,500 + $1,000 = $3,500. An SPI of less than 1 indicates your project is behind schedule, whereas a value > 1 means you are ahead of schedule. Esso si limita ad indicare se il lavoro è in linea con la pianificazione o no. Suddenly the CEO walks in and wants to know from you: ‘How’s the project doing? Use earned value with baselines to track the progress of your schedule. Let’s transfer the example to the world of project management. E‘ un metodo che consente al project manager di misurare la quantità di lavoro effettivamente eseguito su un progetto. Moltissimi esempi di frasi con "earned value analysis" – Dizionario italiano-inglese e motore di ricerca per milioni di traduzioni in italiano. Organizations across all the industries use Earned Earned Value analysis techniques to understand the health of their projects. Insieme, questi due valori determinano un valore importante: il valore pianificato o planned value (PV). Una formula comune per determinare l’EAC è espressa come budget al completamento diviso per l’IPC corrente del progetto: EAC = BAC / CPI. The earned value analysis (EVA) is a project controlling procedure and is one of the key performance indicators of a project, like the cumulative flow diagram. Controlling schedule is an important project management task in which the actual progress of the ongoing project activities are compared with the schedule baseline to determine whether the project is ahead of the planned schedule or behind. Once we get to the actual example where we calculate the metrics, things will become clear for you.
