Nowadays, as society develops in a rapid pace, the scale of company has been enlarged a lot. So, making a right decision is very crucial for its developing. Then data plays a key role in this part. Because the advanced technology makes it easier to collect data and these data allow the manager to observe the information that they have never seen before. However, there are some firms that ignore the importance of the data and make decision by their own. They prefer to depend on their own knowledge than to rely on the data. But this behaviour is much too advocacy. With the increasing importance of the data, the role of a manager really changes. They become more reliable on the data instead of their own knowledge. Therefore, the data-driven decision should be pursued.
In order to take advantage of the data, managers and analysts need to test it and make it a reality. They have to understand the power of the data and cooperate with each other as well.
Anyway, the company which wants to observe a big achievement is demanded to utilize the data correctly because data is important for decision making.
