Dear schedulers,

I am trying to re-baseline a schedule that have already progress. I should track the performance of this schedule using EVM, But when assigning this baseline (with progress)and prior to change the Data Date, my SPI is > 1 while logically it must be equal to 1 because the project is on schedule.
Any suggestions?

    If you are using P3e, check that your PHYSICAL percentage complete is correct. It should actual cost over budgeted cost expressed as a percentage.
    Could also use cost at completion if the costs are different...
    We use it here at NR and it works well.
    Hope this helps

    This is a problem with Primavera.

    It wont calculate the SPI correctly when there is progress on the baseline.

    You will notice that the bars in the gantt dont align properly either, but this can be altered by doing a global change to make the planned start/finish equal the start/finish dates (on the baseline programme).

    However, i dont believe it is possible to change the cost profile that is used for calulating the SPI...which is why progressed baselines give an unexpected answer...makes me feel sick...but even project can do it.

    Hi Sonia,

    Since the baseline has actuals, then in Admin menu - Admin Preferences - Earned Value tab - Earned value claculation, select "Budgeted values with current dates" when calculating earned value from a baseline.

    Hope the above works for you.

    Best regards,
    R. Catalan

    Sonia,

    Just note what Mr.Catalan has stated will work, but will also affect how EV is calculated on all projects within your database!
