introduce
Any enterprise decides to introduce OA products based on the standard of input-output ratio. A set of excellent OA products can bring more valuable returns to enterprises, so no enterprise is willing to pay the extra expenses that could have been avoided, otherwise it would be tantamount to wasting enterprise resources.
Therefore, when measuring whether a product is excellent enough, we should also include all its costs, including explicit costs and implicit costs. Due to the limitation of technology and concept, the purchase cost of traditional and project-based products is already very high. In addition, users have to bear more follow-up costs in daily operation and maintenance and follow-up development.
Because of the innovative platform development technology, the procurement cost and daily operation and maintenance cost of platform products are greatly reduced, with excellent cost performance. Besides, they don't have to pay too much for redevelopment. Comprehensive measurement will provide excellent input-output ratio for enterprise users, and they will have excellent rate of return.
