  32. Integrated Information Systems • Reasons for Integration • using twentieth-century computer technology, which is functionally oriented : • cannot give employees all the information they need • do not let different departments communicate effectively with each other in the same language • crucial sales, inventory, and production data often have to be painstakingly entered manually into separate computer systems every time a person who is not a member of a specific department needs ac hoc information related to the specific department

  33. How to Integrated Information Systems • Connect existing systems • maximize the use of existing systems and minimize the changes in them • allows the addition of new applications to existing ones and the connection of systems to intranets and the Internet • Using supply chain management software • use one integrated package in one or several functional areas • overcomes the isolation of the traditional departmental structure where the functional areas are separated from one another

  34. How to Integrated Information Systems (continued …) • Enterprise resource planning (ERP) • control all major business processes with a single software architecture in real time • increased efficiency to improved quality, productivity, and profitability • SAP software (R|3; my SAP.com) • crosses functional departments and can be extended along the supply chain to both suppliers and customers • composed of four major parts : accounting, manufacturing, sales and human resources

  35. Sales Offices The factory automati- cally receives the sales order and can begin production. FACTORY The warehouse is si- multaneously informed about the order and can schedule shipping. WAREHOUSE Accounting gets up- dated sales and pro- duction data at every step of the process ACCOUNTING HEAD QUARTERS Headquarters can tap into up-to-the-minute data on sales, inven- tory, and production ERP • SAP concept Central SAP Database & Servers
