Thanks Vic, that helped a lot! I created a chart off the matrix report, and that worked very will with my business stakeholders. Of course, the immediately wanted a cumulative view of the data, which would produce a traditional S-curve chart. I haven't figured that out yet, without dumping the report to Excel and hacking on it there (yuk!) The SPI thing makes sense. I'll experiment a litte. If they don't use baseline for the calculation, but instead used Planned Cost, then as a PM removes or reschedules uncompleted work, the SV calc (SV = EV - PV). I presume EV is the planned cost for the completed work (as you say, not the baseline), and if uncompleted work in the past is eliminated or rescheduled, then we have PV approaching AC, so SV would approach zero and SPI would approach 100%. Thanks again, and let me know if there is some trick to get S-curves from workfront. Max Max Fritzler
