The traditional hierarchical management has the characteristics of clear hierarchy, clear responsibilities and strict workflow. It originates from the imitation of military management system and is widely used in various fields such as government agencies, production and manufacturing. At the same time, with the growing size of the organization, the relationship between managers and managed people becomes more complex, and each manager's ability, energy and time are limited. When the number of subordinates directly managed exceeds a certain limit, a management level must be added. With the levels increase, the staff at different levels and even at the same level will easily reduce the timeliness of information transmission because of the objective differences in the degree of recognition of the importance of information, work habits, etc. At the same time, because of the objective differences in the growth background, work experience, knowledge background and understanding ability of the relevant personnel, it is easy to lead to information misunderstanding in the process of interaction, and affects the accuracy of information interaction s. Thirdly, in the actual work, it is difficult for a superior to supervise the deployed tasks, whether the subordinates can actually accomplish the tasks and how to accomplish and the quality in the case of non-face-to-face. If we cannot establish a convenient information interaction mechanism, it is difficult to supervise. In response to such problems, OA (Office Automation) systems have been widely used, but the result has proved that most OAs simply transplant the traditional hierarchical management to the Internet. There are still objective problems such as layer-by-layer reporting, layer-by-layer approval, layer-by-layer circulation, and so on. Some departments, no matter how urgent the things are, no matter whether they need to be flexible or not, only depends on the approval result of OA system. Nevertheless, all exemptions aggravate the occurrence of bureaucratic phenomena in departments. At the same time, instant messaging tools such as WeChat and QQ have become the main platform for people's daily interaction because of their main features such as abundant graphics and texts (rich media), self-editing and expressing content (self-media), strong sense of scene, being able to publish contents at any time (spatio-temporal dimension), and being able to immediately reach the audience (point-to-point, point-to-point) and so on. And they also have become the the big data platform that carries ideas, delivers business, communicates work and so on, many units, departments or individuals have been accustomed to handling work affairs on the instant messaging platform such as WeChat and QQ. In fact, this phenomenon contains a lot of risks. The main reasons are as follows: 1) the data generated on the platform are taken away by the third party (Tencent and other companies). The business content of the unit becomes the data resources stored on other people's servers. The privacy of the unit has a great risk of leakage. At the same time, because the data is not in its own hands, it is very difficult for the unit to exploit the data resources and make them become driven power of business and management; 2) WeChat and QQ belong to social platform, with complex social relations and prosperous and diverse platform content. Business information can easily be disseminated or leaked intentionally or unintentionally, which not only affects the image of the unit, but also may cause huge negative economic and social impact; 3) Because of the existing characteristics of the platform, important business information can easily be diluted. For example, important information such as tasks and business guidance issued by different leaders in the same group can easily cross each other, leading to confusion in business discussion clues, and difficult to form clear, complete and clear information topics. In order to solve the above problems, this paper designs and develops a flat management platform supporting business data self-owned and self-analysis, relying on mobile internet, which aims to improve the management efficiency, make data as the core asset, and enhance the information interaction ability and efficiency within the unit. The platform has a dedicated data acquisition, publishing, collation and analysis backstage, which not only improves the timeliness, on-the-spot, rich media and cross-temporal dimension of information interaction, but also combs, excavates and refines the data to form the tracking and objective analysis of business progress. At the same time, in order to enhance the pertinence and practicability of the platform, this paper considers the real needs from Hebei province expressway Zhang Cheng Chengde management office. The platform has been put into use and improved for more than two years. Practice has proved that the platform provides strong support for the management department in discovering hot spots, capturing problems, monitoring the overall situation, effectively improving the cohesion, combat effectiveness and centripetal force of the whole staff, and effectively improving the management efficiency.
