Once I read (Oliver 2012) “When you have to make a hard decision, flip a coin. Why? Because when that coin is in the air, you suddenly know what you’re hoping for.” How would you make important decision for your company? Will you trust to your “gut”, flip a coin, or carefully processing all? What do you think - flipping a coin can apply to a very important decision for manager? In our time, when economy is very competing, business is a very complex act that is established by serious decisions, and I think that coin flipping will not help in this case. Every day we are making decisions no matter who we are, or which position we take: employee, managers, CEOs -everyone is making decisions that affect their job, workplace and company they work for (Robbins, Coulter2007 p. 156). All depend of decision making person- what manager is, his perception, and how his mind works (Slocum, Hellriegel 1983, p. 58).According to Robbins and Coulter (2007 p.156-157) then decision-making process is a very important skill for manager, because everything of in this job involves decision making, and on manager’s decision depends all organization’s future – success or failure.
