Introduction and case analysis of ERP system principle and implementation

Enterprise resource planning (ERP) system is an important symbol of enterprise management modernization and an important means to improve enterprise market competitiveness. In the past 20 years, academia, software development companies and enterprises have invested a lot of manpower, financial resources and material resources, and have made continuous exploration, and found a mode and way of ERP system software development and implementation suitable for China's national conditions. At the same time, a large number of ERP system implementation practices have been carried out, and the principles and implementation methods of ERP system have been continuously improved. The implementation of ERP system in enterprises has become an important symbol of enterprise informatization and a development strategy for continuous improvement of enterprise benefits. However, on the whole, the benefits of implementing ERP system in enterprises are not ideal, and it is often difficult to achieve the expected goals. The implementation results are far from the expected goals. There are some problems such as long construction period, high risk, large investment, slow effect and poor controllability, which have not been well solved so far.

Aiming at a series of problems in the implementation and operation of ERP system, combined with our years of ERP system implementation practice and theoretical research, this book refers to a large number of papers, works, scientific research reports and classic cases about the principle and implementation of ERP system at home and abroad, which are summarized, summarized and refined. Based on the development of ERP system, this book studies the principle of ERP system, the theory, method and process of ERP system implementation project planning, analyzes the key factors and solutions that affect its success or failure in the whole process of ERP system implementation, and emphasizes that ERP system implementation is a complex large-scale system engineering. Therefore, before the ERP system project is implemented, it is necessary to do a good job in project planning, planning, consultation and staff training, and strictly divide the engineering stages and stage objectives, process objective evaluation indicators and evaluation methods in the implementation process. The main features of this book:

1. Powerful system. This paper not only systematically introduces the basic concept, basic knowledge and operation principle of ERP system, but also systematically introduces the planning before implementation, the control during implementation and the evaluation after implementation of ERP system, and evaluates the enterprise informatization level before implementation of ERP system with quantitative methods as the theoretical basis of ERP system implementation planning.

2. focus. Around the three centers, this book focuses on the principle of ERP system, the whole implementation process of ERP system and the implementation cases of ERP system. Emphasize the combination of evaluation and feedback in the implementation process to avoid irreparable losses caused by problems found afterwards.

3. Strong practicability, integrating theory with practice. Basic concepts, basic knowledge, principles, cases and confirmatory experiments, cases and cases are organically integrated, which is convenient for readers to master and understand.

4. The content is concise. Carefully arranged in the content, strive for simple operation, easy to understand and master, and strong practicality; Taking the ERP system implementation project as an example, the theory and method of relational ERP system are systematically introduced.

5. Widely used. This book is written for graduate students majoring in economics, management, machinery and computer, and can also be used as a self-study book for manufacturing information engineering technicians, enterprise information engineering technicians, enterprise information engineers, data administrators and information technicians.
