One of the methods includes receiving, from a user, a request to remove a node from a hierarchy, wherein the hierarchy is a directed graph having nodes and links, wherein each node in the hierarchy represents a software element in the project and each directed link in the hierarchy connects a corresponding pair of nodes and represents containment of a child software element represented by a first node of the pair by a parent software element represented by a second node of the pair. If a parent element of a disjoint-or tree corresponds to a parent node of the removed node, a union of dependencies for the removed node is determined. The union of dependencies is then subtracted from the parent element and from every ancestor element of the parent element.
