Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

In our previous month’s update we had a forecast (remaining early)of 10 million for this month. This month our actual is much less than last month and is around 5 million. We have assigned previous month’s update as our baseline for this month. So that 10 million forecast is now our baseline. But still our SPI is 1 in P6! So even though our progress is half of our baseline our SPI is still high. Any idea what is causing this?

We only show revenue in our project. Baseline for earned value is previous month’s update which in our current month we have slipped a lot but SPI is 1!!

Your talk of "actual" is confusing, SPI is a measure of Earned, not Actual. No change to Actual Hours changes SPI.

Which baseline are you using to calculate Earned Value in the Project's "Settings"
