For a long time, Dongfang Electric Group Dongfang Steam Turbine has practiced the lean core concept of "full participation, collaborative and efficient, eliminating waste, and continuous improvement", promoted lean management with high quality, and innovatively put forward "two only" as an important idea for enterprises to implement lean management.
"Two only" means that as long as the non-core business can be socialized, it will be socialized, and the core business will be digitized as long as it can be digitized. In recent years, under the leadership of the "two only" thinking, Dongqi has taken a series of measures in the two aspects of "socialization" and "digitalization" to promote the integration of lean management into all aspects of enterprise operation, realize the continuous improvement of value creation capabilities, and continue to build the company's core competitiveness.
Core business screening.

Socialization of non-core businesses. Focusing on the core concept of lean management "eliminating waste" as the main line, we will vigorously promote business and assets, actively realize the socialization of non-core business, solve a number of "bottlenecks" that restrict the efficiency of enterprise management and the improvement of business performance, stimulate the vitality of lean management, and promote the improvement of macroeconomic indicators and management level of enterprises. In 2022, the company's operating income, market orders, total profits, payments**, net cash flow from production and operation, and comprehensive product output will achieve double-digit growth year-on-year, reaching the highest level in history and continuing to rank first in the same industry in China.

In 2022, the annual output increased by 27% due to lean digitalization, and the quality problems of parts decreased by 39%, injecting a boost into Dongqi's increase in orders and ensuring delivery.
