In Germany, on the other hand, and equally in Japan, the question has been taken up as a concrete problem, just as definite as a problem in engineering. They have used for solving it the method called "The Estimate of the Situation," originated by the German General Staff, which is now adopted in all the armies and navies of civilized countries for the solution of military problems. Previous to the adoption of this method the general procedure had been such as is now common in civil life, when a number of people forming a group desire to make a decision as to what they will do in any given contingency. The usual procedure is for some one to suggest that a certain thing be done, then for somebody else to suggest that something else be done, and so on; and then finally for the group to make a decision which is virtually a compromise. This procedure is faulty, and the decisions resulting are apt to be unwise; because it is quite possible that some very important factors may be overlooked, and equally possible that some other factors be given undue weight. Furthermore, a measure advocated by a man who has the persuasive and emotional abilities of the orator is more apt to be favorably considered than a measure advocated by a man not possessing those abilities. In the "Estimate of the Situation" method, on the other hand, the orator has no opportunity, because the procedure is simply an accurate process of reasoning. It is divided into four parts. The first part consists of a careful study of the "mission," ending in a clear determination of what the "mission" really is--that is, _what is the thing which it is desired to do?_ The second part consists of a careful study, and eventually a clear comprehension, of the difficulties in the way; the third part consists of a careful study, and eventually a clear comprehension, of what facilities are available with which to overcome the difficulties; the fourth part consists of a careful study of the mission, difficulties and facilities, in their mutual relations, and a "decision" as to what should therefore be done. Military and naval people are so thoroughly convinced of the value of this method that they always employ it when making important decisions, writing down the various factors and the successive steps in regular order and in complete detail.
