As a leader you are bombarded with decisions daily. Some are much bigger than others. With that being said, there are two styles of decision-making. One leads to division and disharmony. The other leads to understanding and commitment. In a post for Voices on Project Management, Lynda Bourne thoroughly explains these two styles.
Making Decisions That Get Supported
First, you have the divisive decision-makers, who value looking strong and fast. Even when their input is not needed, they rapidly review every little issue and make fast decisions. Then they go to lay down the law, with no room for discussion or suggestions. This way of decision-making is not effective for various reasons: the assumption that the leader always knows best, lack of consensus, no team commitment to implement decisions, and a high risk that decisions will stop being implemented once the manager looks away to focus on the next important decision. All in all, it is the unfortunate fact that most confuse an assertive decision-maker with being an effective decision-maker, which is not the case.
Compare the above with the decisive decision-makers. They do not rush to make a decision because there are multiple dimensions that go into its success. As well, if they want to get the desired result and for it to stick they require the collaboration of others. The decisive decision-maker considers: How urgent is the decision? Does the leader need to make the decision or does the leader need to facilitate a decision-making process? Why type of decision is being made?
Through decisive decision-making, the leader empowers the team and builds commitment to the overall project. This is the type of leader you want to be. You can access the original post here: http://www.projectmanagement.com/blog-post/24186/Are-You-a-Decisive-or-Divisive-Decision-Maker-
