STOP WORK HERE
37% OF WORK LEFT (TO BE DONE)
Exp.CurveExp.Curve
When to stop work!• We stop work when curve starts to go
in saturation!
Exp.CurveExp.Curve
Large number of portal with different Locations ...
...end up with different results
Exp.CurveExp.Curve
Portals behave similar ...
... We select best portals !!!
Exp.CurveExp.Curve
There are differences • Depends if portal is already live?• If work will be continued after planed period • etc....
