Often unsolvable problems can be decomposed into a set of solvable problems and hopefully just one or a few unsolvable problems. By narrowing the unsolvable problem it can help to communicate the issue to others (e.g customers or management) or help to find a solution. If that fails it provides some solvable problems to work on. Often solutions, workarounds, or compromises become evident over time.
