All change order modify the baseline in some way, such as cost, scope or time. but we do not create a new baseline everytime.
how do we reflect this change order which only modifies part of the basline, in the baseline?
for example, lets say we are building a house, and a change order added a 10 meter wall. we add an activity or activities for building that wall, put in its durations resources, money into it ... and when we do earned value calculations, how does it work for this, for something that did not exist before? This is my question I guess
