As Vaniver mentioned, it relates to exploring trade-offs among the various goals one has / things one values. A certain amount of it arises naturally in the planning of any complex project, but it seems like the deliberate practice of introspecting on how one's goals decompose into subgoals and on how they might be traded off against one another to achieve a more satisfactory state of things is an idea that is novel, distinct, and conceptually intricate enough to deserve its own label.
