17/4
We need help in solving the following problem or problems. We cannot solve them alone, and cannot proceed unless we solve them.
This code is a clear request for help. It may be that the problems require political help or technical help that is not available on site. Code 17/4 may be used directly on its own as a request for help. It is not just a reason why a project is behind schedule. It may even be used in anticipation - before a project falls behind schedule. Asking for help may be seen as a sign of incompetence. On the other hand, knowing when help is really needed is a mark of competence.
