systems to meet these needs. The expert system coordinates the flow of information from the customer, to the sales agent, and to the factory floor。 it ensures that the products and manufacturing steps meet the customer’s specification. Justintime Inventory JIT reduces cost by obtaining inventory precisely as need— neither too early nor too late. JIT requires puters and information systems to monitor plex and interrelated inventory, and to plan and monitor the Needs analysis 同,完成的工作相同。這種業(yè)務(wù)流程的重新設(shè)計(jì),也被稱為業(yè)務(wù)流程再造( BPR的),需要最大限度地利用信息技術(shù),打破傳統(tǒng)觀念如何組織完成其工作。 一個(gè)公司的產(chǎn)品和服務(wù),質(zhì)量差,不僅影響到客戶的看法,而且還增加公司的成本。組織第一次診斷以質(zhì)量為導(dǎo)向的信息需求,然后再設(shè)計(jì)的戰(zhàn)略信息系統(tǒng),以滿足這些需求。專家坐標(biāo)信息系統(tǒng)的流動從客戶,到銷售代理,并到工廠車間,它保證了產(chǎn)品和生產(chǎn)步驟滿足客戶的規(guī)格。 降低生產(chǎn)成本,需要準(zhǔn)確地獲取庫存,既不太早, 也不太晚。準(zhǔn)時(shí)化要求計(jì)算機(jī)和信息系統(tǒng),以監(jiān)測復(fù)雜和相互關(guān)聯(lián)的清單,并計(jì)劃和監(jiān)測需求分析,維護(hù)系統(tǒng)的分析,執(zhí)行系統(tǒng)的設(shè)計(jì)。開發(fā)企業(yè)外部環(huán)境的企業(yè)內(nèi)部環(huán)境的物流需要,以補(bǔ)充庫存。 6 Maintenance Systems analysis Implementation Systems design Development Enterprise external environment Enterprise internal environment logistics required to replenish inventory. Flattening Advances in telemunications and improvements in working hardware and software spurred panies to use MIS to reorganize. Technology allows the flattening of organizational hierarchies and reduction in the number of managers motivated by the movement to teambased management. Improvements in munication technology have also supported the management of geographically separate business units from a central corporate headquarters. 4. The Development Trend of MIS Using Computeraided System Engineering (CASE) CASE is a method that defines business relationships, activities, processes, entities, and attributes (known as data definitions). CASE reduces duplicate information and quickly reconciles data among subsystem models.

As system engineers identify application business requirements, the system automatically maintains actual documentation. Once analysis and design are plete, database structures and program source code are automatically generated. Creating Interorganizational System with the Inter A growing number of panies are using the Inter to create interorganizational systems and check out the petition. For creating interorganizational systems, most organizations are simply using the Inter to create customer integrated systems and perform electronic data interchange with suppliers and customers. Others have begun to take advantage of the Inter to form electronic information partnerships for sharing information. 5. Application Example of MIS ERP system is one of
