The Art of War - Chapter 1 - Part 4
Having defined that which is to be measured, Sun Tzu provides examples of things to be considered when examining the five measures. He recommends determining which leader has captured the cultural mindset:
Has the Way?"
And, which has the poitical and organizational advantage:
"Which side has
Heaven and Earth?"
Who has the strength and rigorous enough approach to discipline to follow the processes they have defined as their path to success.
"On which side
Is the stronger?"
According to Sun Tzu, understanding these will help you "know" victory and defeat. This is an important point to spend some time on. The idea is not that if you study these things, you'll win; but that if you study these things, you will be able to foresee who will win... which leads to a principle introduced later that is (simplified) never take on a battle you have not already won.
Following this thought, if you stick with Sun Tzu, follow his rules, he promises to lead you to victory. If you follow his guidelines, the Art of War will get your back and keep you from harm. However, this is going to include knowing when to back down, when to back away and when to take action in a way that is decisively final. In the workplace, my experience has been that the last part if often more difficult for people to adopt than the backing down. (But there will be much more on this later.)
Sun Tzu also goes on to explain that if you don't adhere to these rules, whether you use the Art of War or not, you've already ensured you will fail. This is another critical point in the Art of War. What Sun Tzu has essentially done is stated that if you stick with him 100%, he'll guarantee success, anything less than that, and you are not using the Art of War and you will fail.
For those familiar with Scrum, this would be "The Art of War, but..." and it has about the same chances of success as "Scrum, but..." (more on Scrum, but)
This level of commitment is something that appears a number of times throughout the book. It can seem a bit severe when put into practice, but it is something that (IMHO) truly differentiates practitioners of the AOW from those who merely dabble in it. Because war is such nasty business, once you have committed to it, Sun Tzu demands total commitment. At times, this means backing down and at times it can mean pushing further than you might normally. Even taking the time to determine, for yourselves, where the line is in terms of what you are willing to do in order to help the project succeed, can be helpful. As Sun Tzu says, we must know our opposition and ourselves. Often, trick for us as PMs, is to make sure there is a difference between the two.
