When handling changes it must always be considered that no change is as simple as it seems at first. When correcting a simple aspect of a bills of materials it could turn in to a design change and could affect other linked projects. Very rarely is a project a linear structure but or of a branching structure. When one aspect of the branch is changed it could result in changing the rest of the branches as well. This could mean working with other teams or even at times working with other locations. Changes should never occur just to assign work but rather out of a necessity to the good of the projects.
