As we can see from the picture，there is a wooden barrel constructed with a number of boards of different lengths．Some water is leaking out from the edge of the shortest board．
The drawing represents a well-known term called the wooden barrel effect．The total amount of water is determined by the shortest board，rather than the longest one．We can see some practical applications of this effect in our daily life．Teamwork is one of the examples．No matter how well a single capable person performs，without cooperation, communication or help from one another, it will be impossible to achieve the planned target wonderfully. It is always the least capable member that holds back the whole progress of the team．So work together and also help the shortest “board”．The team will perform better with contribution from everyone．
