Who can tell me clearly about ERP\SCM\CRM, what is the difference between these three softwares?

Enterprise resource planning (ERP), supply chain management (SCM) and customer relationship management (CRM) are the three hot spots of information system at present, and they are also the components of e-commerce, among which ERP is the core.

Overview of basic functions of ERP

Based on the latest development of computer technology and management science, enterprise resource planning provides an overall management solution for enterprises (represented by manufacturing industry) from both theoretical and practical aspects. ERP generally includes management ideas, software products and management systems.

ERP transcends the traditional concept of MRP II, absorbs management ideas such as JIT and TQC, and expands the scope of management information system. Besides finance, distribution, production management and human resources, ERP also integrates many functions, such as quality management and decision support, and supports Internet, intranet and extranet, e-commerce, etc.

Overview of Basic Functions of Customer Relationship Management

Customer relationship management (CRM) originated from1contact management put forward in the early 1980s, that is, collecting and sorting out all information related to customers and companies. Customer Relationship Management System (CRM) is a new application system, which manages the information about the market and customers in a unified way, and can effectively analyze and process these information. It provides comprehensive support for internal sales, marketing and customer service. CRM has a broad application space in helping enterprises reduce sales costs, increase income, find new markets and new channels needed to expand their business, and improve customer value.

The basic functions of enterprise CRM system include sales management system, marketing management system, customer service system and call center.

Overview of Basic Functions of Supply Chain Management

Supply chain management refers to various activities and processes of planning, coordinating, operating, controlling and optimizing the whole supply chain system, and its goal is to produce the right products that customers need at the right time. According to the correct quantity, quality and status, it should be sent to the right place, that is, "6R", and the right person should be "7R". And minimize the total cost. Specifically, supply chain management refers to the integrated management mode of supply chain between core enterprises and their suppliers and suppliers, and between core enterprises and their suppliers and users with the support of modern network information technology. Its basic functions are as follows: the function of transmitting information; The function of coordination; The role of technological upgrading.

1.

(1) The three are in different stages of information system development. The development of information system has experienced half a century, and it is a process of continuous accumulation, evolution and maturity. After the mid-1960s, the successful launch of MRP system was a milestone, from MRP with material demand planning as the core to closed-loop MRP system that can adapt to the changes of product production plan and production site conditions, to the production improvement of MRP II with product manufacturing as the core after the 1970s, until the proposal and development of ERP in the 1990s, which shifted the focus of enterprises to the integration of internal and external resources. ERP realizes the push management of supply chain, that is, the process from raw materials to market, which is product-centered. However, with the economic globalization, the market moves from seller to buyer, and the products of enterprises must be converted into profits, so that enterprises can survive and develop. The supply chain turns to pull, that is, from market to product to procurement, the management focus of enterprises turns to the outside, which promotes the development of customer-centered management (CRM) system and solves the problem of how to deeply understand customer needs, respond in time and provide personalized services to customers. At the same time, the idea of supply chain management and other information systems have emerged one after another.

(2) The emphasis and content of the three are different. ERP system is based on information technology, focusing on the systematic management of internal business processes and realizing internal information sharing. Generally speaking, to successfully implement ERP, business process reengineering must be carried out. ERP completes the management of internal supply chain and the integration of internal business processes, and improves the operational efficiency of enterprises through this integration. SCM system was originally developed by ERP. It manages logistics, information flow and capital flow, and plans and coordinates all activities with logistics, information flow and capital flow, making it a seamless process. SCM covers all links in the supply chain, strengthens the coordination of enterprises in the supply chain and the integration of external logistics, capital flow and information flow, and makes up for the deficiency of ERP. CRM system is to cultivate customer-centric business behavior and implement customer-centric business processes. Make up for the lack of ERP in the front desk. By analyzing the data generated in sales activities, it excavates valuable information for enterprises and feeds it back to the marketing activities and production systems of enterprises. It requires mobilizing all the resources of enterprises to serve customers, so as to improve customer satisfaction and loyalty and increase enterprise benefits.

2. The connection between the three.

Whether ERP, SCM or CRM, their fundamental goals are to reduce inventory, speed up capital turnover and improve the management level of enterprises, so as to improve the response speed of enterprises to the market, which should be in line with the overall development strategy of enterprises. The overall development planning of an enterprise inevitably requires the final integration of the three, and the development of technology also provides support for the integration of the three. SCM, ERP and CRM are three inseparable IT systems of enterprises, and these three contents are considered as three elements of e-commerce platform.

(1)CRM and SCM are interdependent. Marketing strategy, sales management and cooperation in CRM have a direct impact on SCM; At the same time, supply chain management will also directly affect customer satisfaction.

(2)CRM and ERP are mutually supportive and interdependent. Firstly, ERP production system provides abundant data for data warehouse in CRM. Secondly, the analysis results of CRM and the prediction of market development provide decision-making data for ERP system. Finally, CRM can improve customer relations, while ERP can improve the competitiveness and profits of enterprises from the perspective of optimizing production processes.

(3)SCM and CRM software can work independently. In order to make the whole system play a great role, it is necessary to have the support of ERP, which is also the basis of e-commerce and e-commerce.

Only when ERP system is combined with SCM and CRM can it form a complete closed loop and give full play to ERP. Therefore, ERP, SCM and CRM are interrelated and complementary.
