SV Negative value But Status On Schedule?

Occasional Contributor



Can someone help explain why my SV value is negative which I understand means my project is behind schedule based on earn value analysis but my project status is showing on schedule? Is there a difference on how status calculates the schedule of the project as oppose to how SV does it. Or am I missing something fundamental here. 


I have attached a snapshot of the Variance table of the project plan. The status date and current date is set as 20 March 2023.


Appreciate help to above query.

Earn Value Analysis makes use of Baseline data while the "Status" field has nothing to do with Baseline. The "Status" field is based on the following fields

  • Start Date
  • % Complete
  • Status Date

E.g. If "Status Date" is Day 5 and a 10-day Task is shown as 50% complete on Day 5, then "Status" field value is "On Schedule" but if this 10-day Task is shown as 20% on Day 5, then "Status" field value is "Late".


A Task that is 100% complete will have "Status" field value as "Complete" while a Task whose "Start Date" is greater than "Status Date" will have "Status" field value of "Future Task".




Thanks for the prompt reply and providing the clarification. Your rseponse much appreciated.
