1, the barrel of water is made of multiple planks, the amount of water is also determined by these planks **** the same. If one of the planks is very short, the amount of water in the barrel is limited, the short board has become the barrel of water "limiting factor" (or "short board effect"). If you want to increase the water capacity of the barrel, you can only replace the short board or lengthen it. People summarize this law as "the principle of the barrel", or "the law of the barrel", also known as "short board theory".
2. No matter how high a bucket is, the height of the water it holds depends on the lowest plank.
3, also known as the bucket principle or short board theory, bucket short board management theory, the so-called "Bucket Theory" is also known as the "Bucket Law", the core of which is: the amount of water in a bucket, does not depend on the highest block on the wall of the bucket, but precisely on the shortest block on the wall of the bucket. It depends on the shortest block on the wall. According to this core content, "Bucket Theory" also has two inferences: First, only all the planks on the wall of the bucket are high enough, the bucket can be full of water. Second, as long as there is a piece of the bucket is not high enough, the water in the bucket can not be full.
The above is a description of what the barrel effect is all about.
