2 Demand analysis
At present, the informatization construction of our unit has achieved preliminary results. However, with the development of the scale of the unit and the changes in market demand, the construction of the government and enterprise informatization system is more urgent. After actual investigation and analysis, our unit is in the informatization construction The main requirements are as follows:
One is to realize paperless office and improve office efficiency. The computer system in our unit has become very popular, and it is necessary to realize paperless office through informatization, and to realize efficient process of official documents and effective communication of information through electronic and mobile methods. In the enterprise card application, the phenomenon of repeated construction of multiple departments is more serious. Each application system exists independently and cannot communicate. Leaders and ordinary employees need to carry different cards for dining in the canteen, book borrowing, and attendance, etc. Because of the leaders and employees There are many documents to carry, which are easy to lose and it is more troublesome to apply for replacement. Each application system is independent of each other, and the exchange and sharing of data and resources have not been realized, which has caused a certain degree of difficulty to the unified management of the enterprise. The construction of enterprise all-in-one card equipment is relatively lagging, and the demand for enterprise information construction is urgent.
The second is to enhance corporate image and strengthen corporate management. My company’s corporate image and management are already in place, but how do we keep pace with the times in today’s informatization? How to manage modern enterprises with informatization methods? China Telecom has given an inevitable answer here.
Third, it is to develop the market in depth and provide convenience for employees. The main purpose of unit employees is to charge sub-wallets and use POS machines. Although some units have more application scenarios for electronic wallets, they still have low integration with public resources and less integration with social-related products, which invisibly creates social resources. waste. How to expand and deepen the application of electronic wallets to provide more convenience to citizens.
