IBM Global Services (ITS) © 2004 IBM Corporation 4 Earned Value analysis 10/30/15 Objectives  Understand project financial data analysis acronyms and formulas  Analyze project data and PREDICT project financial performance  Understand how Earned Value Analysis can enhance the overall project performance
  5. IBM Global Services (ITS) © 2004 IBM Corporation 5 Earned Value analysis 10/30/15 Earned Value Management - Definitions Department of Defense literature defines earned value management as the following: "Earned Value Management is the use of an integrated management system that coordinates work scope, schedule, and cost goals and objectively measures progress toward those goals." PMI/WWPMM Glossary describes earned value analysis as: “The process of comparing actual performance with planned performance using earned value as the method for measuring project performance.”
  6. IBM Global Services (ITS) © 2004 IBM Corporation 6 Earned Value analysis 10/30/15 EV Management – Value (to Organization) 1/2 Benefits are both intrinsic and extrinsic • Meet budget, schedule and scope objectives • Earlier awareness of problems (and resolution) • Improved communication of status • Solid basis for management decisions • Hilft dem Management Bereiche zu identifizieren, die zusätzliche Aufmerksamkeit des Managements erfordern • Helps identify poor or inadequate planning • Liefert die Basis für einen realistischen Plan gegen den die Performance gemessen werden kann • Basis for better planning on future projects • Broadens perspective of many Project Managers • Increased customer satisfaction and profitability • Wenn ein Aufgabe innerhalb Scope, Zeitplan und Budget erledigt werden kann, steigt das Vertrauen in eine erfolgreiche Fertigstellung

IBM Global Services (ITS) © 2004 IBM Corporation 7 Earned Value analysis 10/30/15 EV Management – Value (to Organization) 2/2  Liefert wahre Kostendaten – Verhindert Kostenabweichungen – Ermöglicht realistische Projektionen der Gesamtkosten – Erhöht die Genauigkeit der Kosten-Schätzungen  Reduziert die Möglichkeit des Kunden / Managements zusätzliche Arbeit ohne zusätzliches Budget aufzuerlegen – Verbindet direkt Budget und Arbeit – Erzwingt für zusätzliche Arbeit zusätzliches Budget – Erzwingt für reduziertes Budget eine Reduzierung der Arbeit  Ermöglicht Management Entscheidungen in einem realistischen Rahmen gegenüber latenter Unsicherheit
  8. IBM Global Services (ITS) © 2004 IBM Corporation 8 Earned Value analysis 10/30/15 EV Management - Getting Started Earned Value Management • Requires basic project management practices be in place • Integrate Earned Value (EV) concepts and processes across all components of the Project Management System – Documented in an EV management plan – Uses EV analysis to look at and report on data that is collected and managed as part of regularly accepted project management activities
  9. IBM Global Services (ITS) © 2004 IBM Corporation 9 Earned Value analysis 10/30/15 EV Management - Criteria for Success Successful implementation of EV Management requires: • Determine early if EV Management is going to be used and include in all planning activities • Define a WBS with clearly identifiable and measurable tasks • [Include tasks in support of EV in the WBS and fund them] • Schedule all work within required and achievable time frames • Assign resources and costs/person days to each task • Prepare baselines for budget and project plans • Capture and monitor all project costs • Track progress for scope, schedule, and budget • [Adjust project management efforts as a result of EV analyses (i.e. Recovery plans)]
  10. IBM Global Services (ITS) © 2004 IBM Corporation 10 Earned Value analysis 10/30/15 EV Management - Processes Processes need to be in place • Processes to baseline budgets and project plans and record them • Processes to obtain expenditures from Planview and other accounting systems • Processes to regularly assess and record work accomplished and costs incurred • Processes to generate Earned Value analyses and reports • Processes for reporting status at level of detail needed to measure progress accurately

Summary Level % A declared % of work is allocated for summary activities, and the designated % of work performed is earned at the completion of the activities. Remaining Effort The actual effort expended to date as a percentage of actual and anticipate work to be expended.

IBM Global Services (ITS) © 2004 IBM Corporation 51 Earned Value analysis 10/30/15 Exkurs: 50-50 Regel (Theorie) Theorie • Der Fehler bei einer gerade erst begonnen Aktivität (überbewertet) wird durch eine kurz vor Abschluß stehende Aktivität (unterbewertet) wieder aufgehoben oder ist vernachlässigbar. • Aufgrund der WBS-Detaillierung < 4 Wochen, tritt der Fehler im Folgemonat nicht mehr auf; neu Aktivitäten kommen jedoch hinzu. • Mit zunehmender Projektdauer geht er systematische Fehler gegen Null, da der im Berichtszeitraum liegende Aufwand überproportional kleiner ist als der bereits geleistete Aufwand in den Vorperioden (BCWP Vorperioden >> BCWP Berichtsperiode) • Mit Hilfe der 50/50 Regel wird der obligatorische Schätzaufwand für die geleistete Arbeit vermieden. • Die subjektive Schätzung „wie viel einer Arbeit bereits geleistet wurde“, wird reduziert auf das objektive Eintreten von Ereignissen der Art: – Liegt der Planstart vor dem Berichtszeitpunkt 0% oder 50% – Liegt das Planende vor dem Berichtszeitpunkt 0% oder 50% – Liegt der Iststart vor dem Berichtszeitpunkt 0% oder 50% – Liegt das Istende vor dem Berichtszeitpunkt 0% oder 50%

  53. IBM Global Services (ITS) © 2004 IBM Corporation 53 Earned Value analysis 10/30/15 Pitfalls & Special Considerations  1. Collection of Actuals (Effort Expended and % Complete) isn’t easy.  2. Calculation of BCWP (% Complete) must be discrete.  3. Changes in scope require “Re-Baselining” BAC.  4. Remaining Effort should not be used to calculate % Complete.  5. Works Councils may prevent the implementation Time Reporting System.  6. Compute Earned Value with Effort, NOT Cost.
