First, real estate development and information flow analysis
1. development process and system function division
Real estate is an industry with deep industrial chain and complicated process. There are various enterprises with different positioning in the real estate market, such as developers, builders, material suppliers, advertisers, design units and so on. The process of real estate development is a continuous process, from the timeliness analysis report before land acquisition to the research and design of the project, to implementation, and finally to acceptance. The real estate development process and system function division are shown in figure 1.
2. Real estate information flow structure
It is not difficult to see from the figure 1 that the main participants in the capital construction project are the construction unit, the design unit and the construction unit, and of course there are many auxiliary units, such as consulting companies, supervision companies, building materials suppliers, building equipment lessors and electromechanical equipment suppliers. Here, how to realize informatization is considered from these aspects. The information flow structure is shown in Figure 2:
As a special commodity, real estate is physically difficult to move. In a wide range of communication, marketing and management activities, in most commercial activities, only various forms of information can be used as carriers to replace actual goods. In modern society, this information can be expressed through agreements, loushu, various advertisements, model houses, network condolences and other forms. The rapid flow of information can promote the rapid circulation of real estate commodities in the market and improve the efficiency of the real estate market. These three parties' interactive information actually constitutes an important intangible market in the real estate market.
Second, the specific implementation of real estate information flow management
Method instruction for implementing 1
In the concrete implementation of real estate information flow management, we should always be guided by a set of scientific methods and models, so as to make its process management not go against the original goal. These methodological models are methodology. To sum up, this mainly includes:
① Overall project management method. The goal of project management method is to provide a main framework so that it can plan, evaluate, control and track projects through consistent means.
② Methodology of application system implementation. The implementation methodology of application system is a structured implementation method extracted from the implementation of complex application products, which can meet the various needs of users, including all necessary steps from defining the implementation methods and strategies of users to the online operation of new systems. So as to reduce the implementation risk of users as much as possible and ensure the rapid and high-quality implementation of the management application system.
2 Seven stages of real estate information flow management, as shown in the figure.
(1) the first stage, formulate the implementation strategy. Mainly from the business and technology to plan the scope of the project, and determine the objectives of the project. The work at this stage includes the establishment of a project implementation leading group led by the company leaders and a project implementation team attended by relevant personnel from various departments, and the initial training of employees on business management concepts and methods, and the specific formulation of strategies and objectives for enterprises to implement application management.
② The second stage, business and data flow analysis. Business process analysis is mainly to understand the specific business process, describe the current management mode in detail, find and deal with errors and omissions in system investigation, and modify and delete unreasonable parts in the original system. Data flow analysis abstracts the data flow within the organization, omitting the specific organization, information carrier, processing work, materials and so on. The processing mode of actual business can be described by industrial PCR only from the data flow process.
③ In the third stage, design the solution. This paper mainly reviews and analyzes the business analysis processes formed in the previous stage, and combines the basic concepts of business management and specific software functions to propose solutions to various management business processes at present.
④ In the fourth stage, the application system is established. In the wood stage, the improvement plan should be made according to the plan drawn up in the previous stage, including adjusting the division of labor, standardizing the process and unifying the methods. Standard information coding, etc. From the software point of view, we can start the preliminary design and secondary development of the system. In this way, an application system that conforms to the enterprise management idea is established. At this time, a large number of basic data will also be sorted out.
⑤ The fifth stage, document coding. When establishing the application system, in addition to the secondary development of the software and providing necessary documents according to the requirements of software engineering, the original system, responsibilities and flow chart must be compiled or modified to improve the management process.
(6) The sixth stage, system switching. At this stage, in order to reduce the risk of system implementation, various functional departments run computers to test according to their daily business activities and refer to documented processes to confirm that their systems are feasible. At this point, the formal data input, initial state creation, parameter definition and operation of the new system begin. In order to ensure the success of switching, the project leading group requires that multiple orders be issued in time to switch the system step by step. Generally speaking, when new and old systems run in parallel, the risk may be less.
(7) The seventh stage, operation and maintenance. After a period of operation, it is proved that the system is safe and reliable and can be put into operation formally. And do a good job in the operation of the relevant records and reports, timely find problems in the operation for maintenance and improvement.
Three, real estate information flow management also need to pay attention to several issues.
1 Information flow management needs the cooperation of management systems with software operation characteristics.
The so-called management system with the characteristics of software operation here refers to a management system that can be used for reference and suitable for software programming ideas to a certain extent. The system is mainly embodied in work control and personnel operation process management. With this system and software, the use of software will be more scientific and rigorous, so as to achieve the expected management goals. There is a huge difference between computer operation and manual operation. 9 1 Computer operation can enjoy data * * *, and computer operation can be made without repeated labor by many people, without worrying about calculation error W }；; Computer calculation efficiency is high, which can save a lot of labor; The computer can keep the traces of operation and reduce the supervision investment in the manual stage; More importantly, computer operation can ensure objectivity, and so on. In view of the difference between the two, it is necessary to adjust the management system adaptively, otherwise, like an old cow pulling a cart, it will not improve efficiency, but will bring negative effects. Especially in the initial stage of information flow management, staff often shout' it is not as efficient as manual operation'. In addition to unskilled operation or lack of application experience, the main reason is that the management system and previous casual working thinking have not kept up with the changes in the environment. It should be emphasized that apart from the changes of the operating system of these basic trees, it is often easy to ignore the management function of software function expansion. For example, the workflow technology of software requires the cooperation of streamlined working systems. Our real estate trading center has deeply adopted the process work system, changing the previous department approval system into the process work in the business hall, which greatly meets the needs of modern work and avoids the disadvantages of low efficiency, lack of parts, many thresholds and inconvenience under the manual system. For another example, taking advantage of the characteristics of software formulation, our center boldly adopts the system of separating decision-making from execution, instills decision-making into the software, and then controls the executors through the software, thus putting an end to the common disadvantages in administrative law enforcement, such as centralized power, exploiting policy loopholes, fragile constraints, and showing great management power.
2 should reflect the comprehensive application of information technology in management.
With proper software and management system, it needs to be fully applied in work management before it can be considered as scientific information flow management. The vast majority of domestic microcomputer network applications start from local applications. For example, some units first realize financial computerization; Some first realize business computerization; Some took the lead in realizing the computerization of government affairs management or all the management were computerized, but the software systems were isolated from each other, and so on. These are routine practices based on actual national conditions and economic conditions, but none of these units can be regarded as realizing information management. The object of informatization is management. Only when the administrative, business, personnel, financial and other management matters are all managed by computer network, and all parts are coordinated to achieve management objectives under unified software, can it be regarded as information management. In view of this, the "information management" of many units in the real estate industry and other industries needs to be further developed and applied.
Information flow management should be a long-term process.
There are still many problems in information flow management. First, many housing enterprises still have insufficient funds, and this kind of large investment needs to be gradually solved. Secondly, it takes time for employees to change their minds. At present, many enterprise employees and even leading cadres still lack understanding of information flow management, and even resist it. Third, it takes time to accumulate working data. Fourth, technology is updated frequently, and software and hardware need to be updated in a planned way over time. Fifth, informatization is for management, and information systems need to develop continuously with management upgrading. Based on the above factors, real estate information management needs long-term persistence, continuous investment and gradual improvement.
