Abstract:

Many software projects that suffer a lingering death should have been canceled much earlier. Although it is hard to pull the plug on a project with a weak business case, failing to do so does throw good money after bad. Karl Wiegers gives some tips on decision making that can help you avoid this outcome. Karl also shows how to use decision points to keep a good project moving along.
