Software Proiect EVA Tutorial TuTorial on Earned Value ManagemenT SysTems Dennis J Frailey 10 Overview 11 Background In The midsT of a Typical projecT iT is ofTen desirable To esTimaTe such quanTiTies as how much Time is lefTquot or how much of The work is compleTequot ooremind you of Trips in The family car where The children are wondering are we There yeTquot iT is noT surprising JusT as The passengers on a Trip wonder how long iT will Take To geT To The desTinaTion so managers have a responsibiliTy To undersTand how long a projecT will Take To geT To iTs desTinaTion and whaT iT will cosT Those working on The projecT usually wanT To know This Too Earned Value Analysis EVA is a way To measure The amounT of work acTually performed on a projecT ie To measure iTs progress and To forecasT a projecT39s cosT and daTe of compleTion The meThod relies on a key measure known as The earned vaue also known as The budgeTed cosT of worked performedquot or BCWP This measure enables one To compuTe performance indices for cosT and schedule which Tell how well The projecT is doing relaTive To iTs original plans These indices also enable one To forecasT how The projecT will do in The fuTure Earned value acTually uses Three daTa values which are compuTed each week monTh or whaTever oTher period you wish To use We use The Term analysis daTequot To refer To The daTe when The Three values are analyzed Thus if we measure These values monThly an analysis daTe of OcTober 31 would include all values from projecT incepTion unTil The end of OcTober The Three values are c BudgeTed CosT of Work Performed BCWP o BudgeTed CosT of Work Scheduled BCWS o AcTual CosT of Work Performed ACWP Tutorial on Earned Value Management Page 1 Copyright 19992001 Dennis J Frailey All Rights Reserved Software Proiect EVA Tutorial 12 DefiniTion of The Three Basic Values BCWP or BudgeTed CosT of Work Performed or Earned Value This is The cosT originally budgeTed To accomplish The work ThaT has been compleTed as of The analysis daTe IT answers The quesTion how much work has acTually been compleTedquot BCWS or BudgeTed CosT of Work Scheduled or Plan This is The ToTal budgeTed cosT up To The analysis daTe IT answers The quesTion how much did we plan To spend as of This daTequot A varianT of This quesTion is how much work should have been compleTed by This daTequot BCWS can be compuTed from The projecT39s plans as iusTraTed in The sequel or iT can be approximaTed by mulTiplying The ToTal budgeT by The fracTion of ToTal projecT duraTion aT The analysis daTe Thus for example if The projecT budgeT is 100 and 20 of The projecT39s Time has elapsed The approximaTe BCWS is 20 ACWP or AcTual CosT of Work Performed This is whaT iT acTually cosT To accomplish all The work compleTed as of The analysis daTe IT answers The quesTion how much have we acTually spenTquot This is usually deTermined from The organizaTion39s accounTing sysTem or can ofTen be approximaTed by mulTiplying The number of people by The number of hours or days or weeks worked 13 Derived MeTrics Four measures can be compuTed from The basic values described above 0 Schedule Variance SV 2 BCWP BCWS If H is 0 you are righT on schedule If iT is negaTive you are behind schedule If iT is posiTive you area ahead of schedule 0 Schedule Performance Index SPI BCWP BCWS If H is 1 you are righT on schedule If iT is less Than 1 you are behind

Proiect EVA Tutorial If iT is 0 you are righT on budgeT If iT is negaTive you are over budgeT If H is posiTive you area under budgeT o CosT Performance Index CPI BCWP ACWP If iT is 1 you are righT on budgeT If iT is less Than 1 you are over budgeT If iT is greaTer Than 1 you are under budgeT 20 Using EVA To DeTermine Where you Are 21 UniTs There are many ways To measure quotcosTquot For example we could measure acTual money spenT However iT is common in a work environmenT To measure cosT in Terms of abar ThaT is in work hours or work days spenT Thus The budgeT for a projecT could be 30000 or iT could be 300 labor hours and The amounT spenT so far could be 4500 or H mighT be 45 labor hours EVA can be used wiTh any measure of cosT buT H is imporTanT To decide which one To use We will use an example in dollars in This secTion and an example in work days in The sequel 22 An Example using Dollars Suppose you are making cookies for a large parTy To be held Tomorrow Suppose The following are your plans Plans 40 cookies per baTch 5 baTches per hour 200 cookies Schedule 5 hours To make a ToTal of 1000 cookies BudgeTed cosT per cookie is 005 ToTal budgeT is 5000 for cookie ingredienTs or 10 per hour We39ll use earned value To examine our progress Progress ReporT aT End of Hour 1 o 150 edible cookies have been made some were burnT and had To be Thrown away 0 ToTal acTual cosT of ingredienTs used so far is 900 ACWP Tutorial on Earned Value Management Page 3 Copyright 19992001 Dennis J Frailey All Rights Reserved Software Proiect EVA Tutorial Analysis BCWS 1000 BCWP 750 Earned Value 150 cookies x 05 per cookie ACWP 900 from above Therefore SV BCWP BCWS 250 you are behind schedule SPI BCWP BCWS 075 you are running aT 75 of The planned schedule CV BCWP ACWP 750 900 150 you

cookies if your success aT making Them does noT improve STripped of all The verbiage imagine someone Telling you aT The raTe you are going H is going To Take you all day and iT will cosT more Than you bargained forquot EVA enables you To say ThaT in more precise Terms Perhaps for making cookies such precision is noT essenTial alThough if The predicTion was 44 hours you would have someThing To worry abouTl BUT for running an expensive projecT EVA can be very helpful even essenTial 40 Can we CaTch Up 41 ToCompleTe Performance Index Once we reporT ThaT our projecT is behind schedule or over budgeT The nexT quesTion is usually can we do someThing To geT back on Trackquot Can we meeT The desired schedule and budgeT despiTe The facT ThaT we are running behind Two indices are compuTed To help deTermine This The ToCompleTequot performance index is an indicaTion of how we musT perform for The duraTion of The projecT in order To meeT our desired cosT goal If TCPI is greaTer Than 1 we musT perform beTTer Than planned in order To meeT The goal and if less Than 1 we can geT by wiTh performing under our plan TCPI BudgeTBCWP EACACWP where EAC is The amounT we esTimaTe we will spend Looking closely we see ThaT The numeraTor is how much work is lefT To do and The denominaTor is how much we have lefT To spend NoTe Too ThaT if EAC is simply IEAC Then The TCPI is The same as The CPI ie iT indicaTes ThaT if we do noT change our performance IEAC is The correcT esTimaTe of our final cosT Exercise for The reader prove maThemaTically ThaT if EAC IEAC Then CPI TCPI We menTioned Two indices A schedule index can also be developed This is lefT as an exercise for The reader 42 ApplicaTion To The Cookie Example In The cookie example suppose we wanT To finish aT exachy The 50 budgeT Then TCPI 2 5000750 5000900 2 42504100 2 1036 This means ThaT we musT perform aT 1036 of The originally planned performance in order To do This Ie 36 higher performance Than originally planned This may be

Problem If a projecT runs longer Than originally scheduled cosT esTimaTing porTions of EVA conTinue To be useful buT The schedule esTimaTion porTions begin To fail The definiTions of SV SPI and SAC do noT work as described above InsTead They begin To converge Toward quoton schedulequot values and when The projecT is compleTe They show values of SPI 1 SV 2 O and SAC whaTever The acTual schedule Turns ouT To be This flaw in earned value analysis resulTs from The facT ThaT The schedule esTimaTes are based on budgeTs raTher Than independenT evaluaTions of The schedule 62 Possible SoluTions One opTion is To use The values of SV SPI and SAC only unTil The originally scheduled compleTion daTe and noT use Them afTerwards This opTion is simple and iT works well in many cases when The main concern is budgeT overruns raTher Than schedule overruns or when The schedule overruns are noT very large AnoTher opTion is To reesTimaTe The schedule and base all fuTure calculaTions on This new schedule In effecT This is whaT auTomaTically happens wiTh EVA in The end The new schedule is whaTever The acTual schedule happens To be Of course wiTh This approach you never have a very good meThod of predicTing how much The schedule overrun will be A Third opTion is To develop a new index DPI or Delivery Performance Index as an alTernaTive To SPI DPI is based on The original compleTion schedules of The individual work Tasks The specific Terms and formulas are as follows 0 AcTual Time The Time acTually spenT so far in calendar days 0 Days Ahead how many days ahead of schedule you are negaTive if behind schedule This can be derived from The original schedules of The individual work Tasks 0 DPI delivery performance index DPI AcTual Time Days Ahead AcTual Time Tutorial on Earned
