Second, groups were slow in progress. The passage says that groups are more responsive than individuals because of the number of people involved and their aggregated resources. However, the speaker talks about how the firm found out that groups were slower than individuals in dicision making.

Third, influential people might emerge, and lead the group towards glory or failure. If the influent people are going in the right direction there would be no problem. But in cases where they go in the right direction there would be no problem. But in case where the go in the wrong direction, there is nobody that has enough influence to counter the decision made. In other words, the group might turn into a dictatorship, with the influential party as the leader, and might be less flexible in thinking. They might become one-sided, and thus fail to succeed.
