Now I am not saying that as a business leader you should be rash about decisions, however as Jason Jennings and Luarence Haughton say in the title of their book "It's not the BIG that eat the SMALL, its the FAST that eat the SLOW"
Leadership is about making decisions...understanding what are the decisions that need to be made, asking the right questions to find the best answer, understanding what decisions you need to make and what decisions your teams need to make..
Meetings can be such a blocker to speedy decision making, they also can harm the overall decision by diluting the answer to appease people. Successful companies find a way of making speedy decisions, well assessed yes, but knowing that there will always be an element of risk. If there is no risk then you are probably not leading you are following other leaders or companies.
As a modern leader, time is of the essence....as the authors continue
"The fast thinker has a good memory, learns from previous experiences and always learns from failure including the unexpected failures that occasionally take place"
