The fact still is there is undetermined error in the data. This is a perfect example of mismanagement by the boss. First, a good manager should not be totally involved with the detail design but should be aware at all times whether the project is on track or not. So if the timetable slips and the boss is an expert in the problem at hand, the boss should have stepped in or someone of the same knowledge and aided the design team on coming up with the correct answer. If none of the above options seem to be a satisfactory action, go back to Question 1 and think again.
All options seem statisfactory.
