TRANSACTION PROCESSING SYSTEMS

• Perform and record daily routine transactions necessary to conduct business, e.g. sales order entry, payroll, shipping

• Allow managers to monitor status of operations and relations with external environment

• Serve operational levels

• Serve predefined, structured goals and decision making


4

answering them

• Typically have little analytic capability

DECISION SUPPORT SYSTEMS

• Serve middle management

• Support non-routine decision making, e.g. What is impact on production schedule if December sales doubled?

• Often use external information as well from TPS and MIS

• Model driven DSS, e.g. voyage-estimating systems

• Data driven DSS, e.g. marketing analysis systems

EXECUTIVE INFORMATION SYSTEMS

BUSINESS APPLICATIONS

Many information systems transcend boundary between functional areas like sales, marketing, manufacturing, and research and development. Hence, group employees from different functional specialties are required to a complete piece of work.


11

BUSINESS APPLICATIONS

Applications must not be islands of functionality and are indeed cross-functions.


12

BUSINESS APPLICATIONS ARE BASED ON PROCESSES


13

CLASSES OF BUSINESS APPLICATIONS

• Database Management Systems (DBMS)

• Enterprise Resource Planning (ERP)

• Customer Relationship Management (CRM)

• Supply Chain Management (SCM)

• Warehouse Management System (WMS)

• Radio-Frequency Identification and Tags (RFID)

• Electronic Document Management and Workflow (EDM-Wfl)

• Content Management Systems (CMS)

• Geospatial Information Systems (GIS)

• Project Management Information Systems (PMIS)

• Product Data Management Systems (PDMS)

• Computer Integrated Manufacturing (CIM)


14

ENTERPRISE RESOURCE PLANNINGEnterprise resource planning (ERP) systems integrate internal and external management information across an entire organization, embracing finance/accounting, manufacturing, sales and service, etc. ERP systems automate this activity with an integrated software application. Their purpose is to facilitate the flow of information between all business functions inside the boundaries of the organization.


15

CUSTOMER RELATIONSHIP MANAGEMENTCustomer Relationship Management (CRM) is a widely implemented application for managing a company’s interactions with customers, clients and sales prospects. It involves using technology to organize, automate, and synchronize business processes—principally sales activities, but also those for marketing, customer service, and technical support.

CUSTOMER RELATIONSHIP MANAGEMENT

SUPPLY CHAIN MANAGEMENTSupply chain management (SCM) is the management of a network of interconnected businesses involved in the ultimate provision of product and service packages required by end customers. Supply chain management spans all movement and storage of raw materials, work-in-process inventory, and finished goods from point of origin to point of consumption (supply chain).

SUPPLY CHAIN MANAGEMENT

Supply chain planning systems• Demand planning• Order planning• Advanced scheduling and manufacturing planning• Distribution planning• Transportation planning

Supply chain execution systems

Manage flow of products through distribution centers and warehouses to ensure products delivered to right locations in most efficient manner• Order commitments• Final production• Replenishment• Distribution management• Reverse distribution


19

SUPPLY CHAIN MANAGEMENT

Push-based model (Build-to-stock) - Production master schedules based on forecasts or best guesses of product demand; products “pushed” to customers

Pull-based model (Demand-driven, build-to-order) - With IT, manufacturers can use only order demand information to drive schedules and procurement of components or raw materials

Sequential supply chains - Information, materials move sequentially

Concurrent supply chains - With IT, information moves in many directions simultaneously
