Automatic end-of-project forecast
Four ways to estimate the final cost, and the date earned schedule points to
- At today’s cost performanceSAR 490.5M
- If the rest goes to planSAR 465.4M
- At cost and schedule performanceSAR 564.3M
- The PM’s bottom-up estimateSAR 490.5M
- To stay within SAR 412M, cost performance on the rest must rise to 1.68 — above what has been achieved.
