Introduction to Management Information SystemsChapter 7 IS within Organization HTM 304 Fall 07
Learning Objectives • Understand the history of Information Systems and three types of Information Systems • Functional Information Systems: -- Features and Problems • Integrated Applications • Why Integrate? (Value Chain Model) • Three major integrated systems: CRM, ERP, & EAI
Calculation Systems • First Kind of IS (1950-1980) • Perform tedious, repetitive Calculation • Balanced accounting records • Computed payroll • Applied debits & credits to general ledger • Track inventory, etc… • Provide specifically designed, small volume, numeric information
Functional Systems • As the technology evolve, every department develops their own Information Systems • “Single Function” -- independent • Payroll system • Student registration systems • Computer inventory management systems • Automate the process for each functional area (Maintaining the same process, streamlining it…) • Sales and marketing • Manufacturing • Human Resources • Finance, • Etc.
Example: Human Resources Systems • Support recruitment, compensation, evaluation, and development of organization’s employees • Recruiting methods may be simple or complex • Compensation includes payroll, processing and tracking vacation, sick leave, health care, other benefits • Employee evaluation includes publication of job and skill descriptions and performance evaluations • Development and training activities vary • HR system concerns every employee in the organization. You should check the website before you accept the job offer… • CSUSM HR Webpage: http://www.csusm.edu/HR/
IS supported Manufacturing Activities Will talk more later in ERP system
Problem of Functional Systems (inconsistent coding)
Integrated Systems • Combining functional areas to better support business goals and objectives • Porter’s Value Chain Model:
Customer places order Product is manufactured Product is delivered to customer 1+1>2 Simplified Value Chain • Linkages – interactions across value activities • Linkages important source of efficiencies and readily supported by IS • Emphasis on the linkages triggered the movement of Business Process Redesign • -- Dell, Toyota, etc…
Business Process Redesign • Value chain – network of value-creating activities is foundation business process design, or business process redesign (BPR) • Organizations should not automate or improve existing functional systems • Organizations should instead PLUNGE • Create new, more efficient, business processes • Integrate activities of all departments involved in value chain
The Challenges of Business Process Redesign • Projects expensive and difficult • Highly trained systems analysts interview key personnel from many departments and document existing system and alternatives • Managers review results and try to develop new, improved processes • New information systems developed to implement new business processes • Employee resistance to change • Cannot know ahead of time how effective the new processes are • Few successes, and many others failed…
Inherent Processes • Built-in processes provided by software application (Oracle and SAP) Benefits • “Bests Practices” Save substantial amount of money and time in developing new process and system • Proved benefits from other organization. Disadvantage • May require substantial organizational change • Change can be disruptive to ongoing operations • Disturbing to employees • Homogenous processes may not be good for differentiation
Business Process Application Vendors • Page 210, MIS in Use 7-1 • Largest market share: Oracle/SAP.
Three Examples of Integrated IS • CRM – Customer Relationship Management • ERP – Enterprise Resource Planning • EAI – Enterprise Application Integration Note: Different vendors define their own version of the above terms to better support their own products.
Customer Relationship Management Systems • Set of business processes for attracting, selling, managing & supporting customers • Provides single data repository about all customer interactions • Stores all customer data in one place and enables access to people with permissions • CRM components • Solicitation • Lead Tracking (presale) • Relationship management (post-sale)
Enterprise Resource Planning • Enterprise resource planning (ERP) integrates all of organization’s principal processes • Outgrowth of MRP II manufacturing systems • Primary ERP users are manufacturing companies • SAP first & most successful ERP software vendor
MRP MRPII ERP • MRP (material requirements planning) • An Information System that plans the need for materials and inventories of materials used in the manufacturing process • Does not include the planning of personnel, equipment, or facilities requirements. • BOM (Bill-of-Material) List of product materials and subassemblies. (see figure 7-8, page 203) • MRP II (manufacturing resource planning) • Follow-on to MRP that includes the planning of materials, personnel, and machinery. • limited cross-functional..Push • ERP: • All the resources in the entire company • Defined processes to link the resources. (see page 212)
Potential Benefits of ERP Note: However, you need to trade off between the cost and benefit. Not all the business are suitable for change.
Implementing ERP System • CEO needs to be cautious in deciding whether to implement. • Once decided, it may take years to complete. • 3rd party consultant may need to come in to facilitate the process Task 1: Model current business processes Task 2: Managers and analysts compare these processes to ERP blueprint processes and note differences Task 3: Eliminate differences by either • Changing existing business process to match ERP process • Altering ERP system to match business process
Manufacturing Inventory Marketing other Human Resource EAI IT infrastructure Enterprise Application Integration (EAI) • ERP systems are not for every organization • Too manufacture-oriented • Too daunting • Alternative: EAI • Connects system “islands” via a new layer of software/system • Enables existing applications to communicate and share data (“virtual” database) • Provides integrated information • Leverages existing systems • Enables a gradual move towards ERP.
Key Terms and Concepts • Bill of materials (BOM) • Business process design • Calculation systems • Cross-departmental systems / Cross-functional systems • Customer relationship management (CRM) • Customer Life Cycle • Enterprise application integration (EAI) • Enterprise resource planning (ERP) • Functional systems (examples) • Inherent processes • Integrated systems • Linkages • MRP/MRP II • Value chain
