Website Upgrade Incoming - we're working on a new look (and speed!) standby while we finalise the project

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.

Hi,

Is a negative schedule variance indicates that the project will not finish on time?

In my opinion NO. because, as of the reporting period, critical items planned values may be achieved and keeping the completion date on time. meantime few non critical activities may not be started on time, keeping the EV less than the PV.

So negative variance only indicates that the value of work done is not as much as of planned.

Share your opinion

Best Regards

Kannan

Hi Kannan, You are right. Negative SV only means that project is behind, as per the current schedule, on status or control date. It does not give any indication of the future work. For more on variances, you can look at https://www.pmbypm.com/basics-earned-value-analysis/

If you are not doing enough work there will eventually be a major issue -ve SV highlight this.

If you are not doing the right work there is a problem -ve Float highlights this. 

You need both sets of information (and their trends) to really understand the situation on a project. See: https://mosaicprojects.com.au/Resources_Papers_117.html
