For enterprises, OA system is a "tool" to improve the efficiency of internal management, so which functions should be the most concerned factor when enterprises choose OA system, rather than comprehensive. The development technology of OA system is a reference factor, and different development technologies will have certain influence on future maintenance, secondary development and system integration.
2. The system is mature, stable and easy to use.
The use of OA system generally involves most employees in the whole company. A mature, stable and easy-to-use OA system is more conducive to popularization and use, and saves related training, maintenance and service costs.
3. Make full use of the existing server hardware and system software.
This is an important principle to make full use of the existing computer system investment of enterprises and reduce the total cost (TCO) of information systems. For example, if an enterprise has purchased Windows 2000, SQL Server and Exchange in the process of information construction, it should undoubtedly give priority to the OA system of ASP(ASP, Net)+SQL Server+Exchange.
It is suggested that the principle of overall planning and step-by-step implementation should be adopted to prepare for the subsequent informatization construction of enterprises in the future.
4, easy to integrate and expand, and can be combined with other internal business systems.
Generally speaking, the OA system of an enterprise will not be a completely independent system, but often needs to be combined with the existing business system or the business system to be implemented in the future to avoid the formation of information islands and the lack of correlation between multiple systems. At this time, when choosing OA products, we must focus on the scalability of the products and whether there is an interface to facilitate rapid integration with other systems. Moreover, whether software providers can promise to integrate their OA products with other business systems of enterprises is also an important consideration when enterprises choose OA products. In addition, according to my experience, if enterprises need to integrate OA system with other business systems, Domino/Notes platform is often not the best choice. Because business systems of enterprises are generally based on relational databases, query and statistics are their main applications, which is precisely one of the weaknesses of Domino/Notes.
OA system based on J2ee technology architecture has certain advantages in this respect.
5. Pay full attention to the later maintenance and service of OA system.
The objective law of computer application software system is that the cost of maintenance period accounts for about 30% of the whole software life cycle. Therefore, enterprises must pay attention to post-maintenance when implementing OA system, focusing on the following aspects:
(1) There should be suitable internal personnel for the later maintenance of OA system, which should be taken into account in the initial product technology selection.
(2) 2) Whether the OA system has a good technical framework, whether the system management function is powerful (the daily management and maintenance do not need the support of developers), and whether it has better customization function and secondary development interface.
(3) Ask the software provider to provide corresponding after-sales service commitments and write them into the contract, so as to ask the software provider to help solve system problems when necessary.
