The effective leader does not have to pay much attention to  make others feel  that they have been parts of a decision making.Obviously,the main work for the leader is to improve the  performance of the company ,and most people do not concentrate on what parts they can play in the process of decision making .Instead ,they are more likely to want to konw what benefits accquire  after the decision making. I do not agree with the statement that the effective leader should let others feel being parts of a decision making for several reasons .Firstly,it will have an bad impact on the effiency of the decision making if making decisions together.When there are plenty of people disscussing their opinions about a project ,too much imformationwill decrease the effiency of the decision making for the leaders.Secondly,the role leaders play in the decision making is to increase the income  after making the decision .After all,benefits is the most important thing that everyone concerns.because it will directly effect the life standard of everyone .Finally,if others don not be parts of the decision making ,it does not indicate that the leader is not effective .Doubtlessly,when the decision concerning the commerical secrets, it is impossible to let others take part in the decision making.Of course ,if the leader have the ability to let others feel being parts of the decision making when it does not influence the effiency of the decision making . we can conclude that the leader must be very effective because he konws  how to use the power of everyone to help himeself to finish the work .All in all,I think the main work for the leader is to improve the performance of the company instead of pay much attention to let others feel being parts of a decision.
