Abstract::At present, power grid dispatchers usually arrange work tasks acclrding to the importance and urgency of the work in the power outage maintenance work of Guizhou power network equipment. Due to the lack of intuitive and efficient information interaction mechanism between dispatching terminal and factory station terminal, caused some cruising and service workers in self-service transfomer substations wasting plenty time for wating when arrived at the scence and then received orders. When there have lots of repairing assignments,the "in-vain wait" phenomenon is especially prominent,which greatly reduces the work efficiency of them and is a kind of serious waste of human resources. Under the requirement of China Southern Power Grid''s full implementation of lean manavement, these issues need to be resolved. For this reason, this paper first analyzes the causes and harms of the above-mentioned waste,and combs the key factors to reduce waiting waste. Also this paper introduces the there design concepts of airport flight information board, flight punctuality rate and bank service telephone number, and puts forward the idea of developing dispatch operation information board. Based on the Guizhou power grid, the actual implementaion of bulletin board functional design and system delopment framework are explained.
