An apparatus and methods are disclosed for requirements decomposition and management. The apparatus includes a collection module, an organization module, and a graph module. These modules carry out the steps of collecting a project task description, the project task description comprising one or more properties, generating a directed acyclic hierarchy of one or more project tasks associated with the project task description, and generating a directed acyclic hierarchical graph view of the project, wherein the directed acyclic hierarchical graph view of the project comprises one or more nodes representing the one or more project tasks, and wherein the one or more nodes are arranged to graphically illustrate a directed acyclic hierarchical relationship between the one or more project tasks.
