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.

A schedule that yields such a report shall be rejected and required to be revised as such DUMMY projections report says you have a plan that will not meet contractual conditions in the future.

The disclosed variances for every period each represent the projected value at each update. In this case the projected duration variance during each month. The projections for each future period are projections of the projected variance, which does not make much sense. To say "if such trends continue ... is too much of an hypothetical statement.  The author of the chart is essentially saying current projection is wrong as well as any future projection.

this looks like it was done in excel with the schedule pasted into the spreadsheet. It look like uses the number of activities in planned to happen it looks to be a liner projection losing 3 day per month starting in December 2016. I guess the theory is that if you are not doing anything to improve the schedule and just maintain status quo then the schedule will consistently be delayed the same amount of time each month (3 days). 

if you have quantiites assoicated with this activites this will give a rate of installation.
