How is the whole less than the sum of its parts?

The phrase "the whole is less than the sum of its parts" suggests that when individual components are combined, they may not work together as effectively as expected. This phenomenon can occur due to factors like inefficiencies, conflicts, or lack of synergy among the parts. For example, in a team, individual talents may not translate to better performance if collaboration is poor or if roles are unclear. Thus, the overall effectiveness can be diminished compared to the potential of the separate elements working independently.
