The implementation process of enterprise informatization construction. The evaluation indicators of the implementation process of enterprise informatization include four aspects: difficulty, risk, cycle and key elements of implementation. <br>The custom development model usually adopts the method of simulating the existing management model and business process. Under normal circumstances, it will not change the current operation management or change less, so the implementation difficulty is relatively small: the custom model involves too many elements and links Not only is it related to the business management and business process of the enterprise, but also has a great relationship with the technical level and strength of the application service provider. More uncertain factors lead to greater risks for the entire project. <br>For the successful implementation of the purchase model, it will involve the entire management system, system and norms of the enterprise, which will inevitably touch on the very sensitive organizational structure and management system of the enterprise in operation and management. Compared with the customized mode, the purchase mode has fewer error-prone links such as programming and debugging. By combining and rebuilding the existing modes of the purchased commercial software system, you can complete the work of constructing the entire system. Relatively little, and less risk. <br>(4) Expenses required for enterprise informatization construction. The cost evaluation indicators required for enterprise informatization construction include purchase cost and integration cost maintenance cost. The cost of the custom development model is quite different, mainly because two factors cannot be accurately estimated,-it is the development time, and the second is the required human resources, which leads to the inability to determine the highest proportion of the cost of labor in the custom development model, and the total cost OK; and if the cost budget is too different, the application service provider may choose to reduce the function or increase the budget to reduce the loss, thereby increasing the difficulty of enterprise information construction. <br>The high cost of the purchase model refers specifically to large-scale commercial software systems. The cost is not only expressed as the purchase cost, but also needs to cope with the actual situation of the enterprise during the application implementation process. There are relatively high application implementation costs: small commercial software systems such as Financial management, human resource management, etc .; due to the single function, scope of use, high degree of commercialization, simple implementation, but the cost is lower than the custom development model; the commercial software system purchased by the purchase model generally undergoes multi-party testing and application inspection, technical information Complete, easy to use, low failure rate, and provide after-sales service, the use of maintenance costs is mainly composed of service costs

The implementation process of enterprise information construction. The evaluation index of the implementation process of enterprise information construction includes the difficulty, risk, cycle and key elements of implementation.<br>Custom development model usually takes the method of simulating the existing management mode and business process, in general, will not change the current management, or change less, so the implementation is relatively small: the custom model involves too many elements, links, not only with the enterprise's business management and business processes, and the application service provider's technical level and strength also have a very large correlation, more uncertainties lead to the risk of the entire project.<br>To be successful in the implementation of the purchase mode, will involve the entire management system, system and norms of enterprises, will inevitably touch the enterprise in the operation and management of very sensitive organizational structure, management system, is sure to be large. Compared with the custom mode, less programming, debugging and other error-prone links, through the purchase of commoditized software system has a combination of patterns, reconstruction, can complete the construction of the entire system, the required links are relatively few, less risk.<br>(4) The cost of enterprise information construction. The cost evaluation index of enterprise information construction includes the acquisition cost, the integration cost maintenance cost and so on. The cost difference of custom development model is quite large, mainly two factors can not be accurately estimated, - is the development time, the second is the required human resources, resulting in the custom development model accounted for the highest proportion of the cost of labor costs can not be determined, the total cost will be determined;<br>The purchase mode cost is specifically referred to as a large commercial software system, its cost is not only expressed as the acquisition cost, but also in the application implementation process, need to deal with the actual situation of enterprises, there is a relatively high application implementation costs: small commercial software systems such as financial management, human resources management, etc.; Technical information is complete, easy to use, low failure rate, and provide after-sales service, the composition of maintenance costs is mainly service costs

Compared with the customized mode, the purchase mode is less prone to errors such as programming and debugging. Through the combination and reconstruction of the purchased commercialized software system's existing modes, the whole system can be constructed, which requires less links and less risks.<br>(4) The cost of enterprise information construction. The cost evaluation indexes needed for enterprise information construction include purchase cost and integration cost maintenance cost. There is a big difference in the cost of customized development mode, mainly because two factors cannot be accurately estimated, - is the development time, and the second is the required human resources, resulting in the uncertainty of the human cost which accounts for the highest proportion of the cost in the customized development mode, and the total cost will be determined; And if the difference between the budget and final accounts is too large, the application service provider may choose to reduce the loss, reduce the function or improve the budget, thus increasing the difficulty of enterprise information construction.<br>The high cost of purchase mode refers to the large-scale commercial software system. Its cost is not only expressed as purchase cost, but also in the process of application and implementation, it needs to deal with the different actual situation of enterprises. There are relatively high application and implementation costs: small-scale commercial software systems such as financial management, human resource management, etc; Due to its single function, wide range of use, high degree of commercialization, simple implementation and lower cost than the customized development mode, the commercialized software system purchased by the purchase mode is generally tested and applied by many parties, with complete technical data, convenient use and low failure rate, and provides after-sales service. The composition of use and maintenance cost is mainly the service cost<br>
