Moore's law the number of transistors in a dense integrated circuit doubles approximately every two years(18 months). Abstract Reasoning construct a model or representation Goal of MIS Technology fundamentally changing business Information Age - Production, distribution, control of information primary driver of the economy Digital Revolution - From mechanical and analog devices to digital devices Systems Thinking Ability to model system components, connect inputs, and outputs among components to reflect structure and dynamics Ability to discuss, illustrate, critique systems; compare alternative systems; apply different systems to different situations Key elements - Management and use Information systems Strategies Goal of MIS Managing IS to achieve business strategies Five Forces -threat of substitutes from new competitors -competition from existing rivals -bargaining power of suppliers -bargaining power customers Four Competitive Strategies Industry wide, focus, cost, differentiation How information systems vary by scope: Personal - single user; procedures informal; problems isolated; easy to manage change ex. Drugs Sales Person Workgroup - 10-100 user; procedures understood within group; problem solutions within group; somewhat difficult to change. Ex. Physician Partnership Enterprise(main focus) - 100-1k users; procedures formalized; problem solutions affect enterprise; difficult to change. Ex. Hospital Inter-eneterprise - 1k's users; procedures formalized; problem solutions affect multiple organizations; difficult to change. Ex. PRIDE system Information systems and departmental silos -Information Silo: condition that exists when data are isolated in separated information systems. Entities at one organizational level create information systems that meet only one particular need. -integrate data into a single data base, revise applications, allow isolation manage to avoid problems Business Process Reengineering -activity of altering existing and designing new business processes to take advantage of new information systems -Enterprise systems enabled creation of more efficient or more effective processes -Integrated data, enterprise systems create stronger, faster, more effective linkages in value chains -Difficult, slow, exceedingly expensive -Key personnel determine how best to use new technology -Requires high-level and expensive skills, and considerable time CRM applications -Customer relationship management (CRM): suite of applications, a database, and a set of inherent processes for managing all the interactions with the customer, from lead generation to customer service. Every contact and transaction with the customer is recorded in the CRM database. Making the organization customer centric. -Includes soliciting and lead management application, sales applications, relationship management applications, and customer support applications. Purpose of ERP systems (Chapter 7) -Enterprise resource planning (ERP): Suite of applications, database, and inherent processes for consolidating business operations into a single, consistent computing platform -Includes CRM plus accounting, manufacturing, inventory, and human resources applications -Used to forecast sales and to create manufacturing plans/schedules to meet those forecasts. Originated in manufacturing -SAP offers industry-specific customize packages Enterprise application integration (EAI) -virtual integrated system -Connects system "islands" -Enables communicating and sharing data -Provides integrated information -Provides integrated layer on top of existing systems while leaving functional applications "as is" -Enables less expensive, gradual move to ERP Challenge of upgrading/implementing enterprise systems Collaborative management No clear boss • Requirements gaps Features and functions of complex, not easy to identify What to do? Adapt or alter? • Transition problems Careful planning, substantial training, senior management involvement • Employee resistance (Expect it) New technology Employee resistance Change requires effort and engenders fear Threat to self-efficacies Extra inducements needed • New technology The Cloud, mobile technology Pose risks and potential outside control of organization resources Key outputs of MRP -factory orders and purchase orders, rescheduling notices, inputs bills of material, master schedule for the final assembly(independent demand) Information systems and systems: -takes data and converts it into information. Arranged in a way to give it more meaning -assembly of hardware, software, data, business procedures, and people that produces information Components of an Information System: computer hardware, software, data, business procedures, and people that produces information Difference between IT and IS: information technology refers to products, methods, inventions, and standards used for t
