Here is a premise:
According to one executive we met with, change initiatives that are implemented slowly generally fail because staff have too much time to contemplate the potential negative effects that change might bring and rally opposition that ultimately undermines the effort.

Here is a hypothesis:
At least one executive claimed that giving internal resistance time to organize is a major factor in why so many change initiatives don't get off the ground.

Is it possible to conclude that if the premise is true, then so is the hypothesis?
yes
