  2. 2. AssumptionsEarned Value not included within studyContinous over-costEstimated values in italics shaded letter, actual values in ‘usual’ letterNotationFocus in cost, not in durationEconomic deviation analysis, not duration deviationsTwo periods under study
  3. 3. Initial project cost estimationt = t0
  4. 4. €tQ1 Q2 Q3 Q4BAC = EAC Q1BAC = EAC Q1
  5. 5. Q1 finish. Thus, we do knowactual incurred values of theperiodt = end of Q1
