Customers are our mentors,
This phrase means that only through satisfaction of every customer, our very existence is secured. So regardless of department and rank, the standard for all decision should be customers oriented. What do our customers want and what is their dissatisfaction? What are their problems and how are they changing? How can we satisfy our customers? Answers to these questions should always be searched from customers, and the highest value should be assigned to the satisfaction of customers.

Quality is our source of confidence,
In order for quality to become our source of confidence, we should always be able to guarantee best products, and to do so, drastic investment in technology and quality control should be accomplished.

Reform is our life,
Reform is our life. As demand of our customers change constantly and technology and environment change as well, the family of Doosan should always try our utmost best to supply the best satisfaction to our customers. The best of what our customers prefer always comes out tomorrow; that is, it is produced as a new product in the future.

Talented people are our treasure,
Producing the first-class brands and satisfying our customers are made only possible by people. If our employees are not capable to make such products or if they have no will to do so, not only such goal cannot be achieved at all, but also there can be no room for promise, growth, and development. Therefore, management always need to remind itself that employees of Doosan with capable and enthusiasm are the asset of Doosan, and should always support development of employees' ability and to inspire their enthusiasm.
