SUMO engages in continuous self-assessment, research and setting new challenges to create a better space in the future, where man and the environment can coexist in perfect harmony. Through innovative and motivating management, SUMO has set a firm goal of becoming a world-class construction company in the 21st century.

Human-Oriented
A company is inseparable from man, and corporate management should be based on respect for man. Upholding the corporate ideal of "management based on respect for man, "SUMO respects each individual as the holder of noble character and certain inalienable rights, while at the same time rendering efforts to create an environment where each individual can respect himself of herself.

Towards that end, SUMO has nurtured experts in each field through language, and other long-term education & training. Emphasis is also placed on discovering and nurturing human resources with creative and challenging spirit through a rejuvenating system of being open to suggestions. In addition, rewards and promotions are based on performance and competency, rather than duration of service and connections. Innovative intelligence and active posture, rather than authority and self-satisfaction are valued so that each individual can exert his or her capabilities to the full. Through efficient management of human resources, SUMO has made great strides to create an environment where workers are content and highly motivated.

Customer-Oriented
The goal of SUMO is to provide service "for customers" and "for customer satisfaction and happiness." It has always been ready to meet customer demand, accommodating their unique needs and views.

Towards that end, SUMO has established a Total Quality Management (TQM) team in the Planning Office as part of the efforts to operate a customer-oriented quality assurance system. TQM provides education and training to management, office and field personnel, conducts documentation, holds workshops, establishes quality documents, conducts internal quality inspection and renders various other services to create value on behalf of the customers.

Technology-Oriented
To create a more prosperous future, SUMO endeavors relentlessly to provide pleasant spaces where man and environment coexist in perfect harmony in appropriate living environment, industrial space and facilities. Recognizing that systematic development of cutting-edge technology is the foundation of strengthening competitiveness, SUMO has established a Technology Development Committee to research & develop new technologies and schemes as well as to introduce, disseminate and apply such advanced technology. The Committee oversees the collection and adaptation of technological plans and documents, presents seminars, improves & preserves existing schemes, offers technical training, conducts research & development of building materials, and evaluates construction & quality control, and strives to develop and secure the technologies required for productivity improvement and sharpening the competitive edge.
