Week 11 Notes: Information Management


11.1) Trends forcing changes in the work place
  
  
  Virtual office - using wireless and portable technology, people are able to
  work anywhere and anytime.
  
  Automation - the processing of information is automated with computers.
  
  Downsizing and Outsourcing - many companies have opted to outsource certain
  tasks that need to be done rather than pay full time employees.  The belief is
  that the outside companies that specialize in that particular task are more 
  efficient and therefore cost effective than the company's own employees.
  
  Total Quality Management - organizational wide company to continuously improve
  quality.
  
  Employee Empowerment - allowing employees to have access to information that
  was typically only held by management and giving them the power and freedom
  to make their own decisions.
  
11.2) Organizations
  
     
Management tasks: five functions.

    
  
  Three levels of management:
  
  Top management - CEO and vice presidents.  Strategic decisions, long term
  planning
  
  Middle Management - Tactical Decisions, principally organizing and staffing.
  
  Lower Management - operational decisions.  Monitor day to day events, take
  corrective action when necessary.
  
  see chart pg. 11.9
  
  
  Types of Information:
  
  Unstructured - summarized, concerned with future, somewhat subjective.
  
  Structured - highly accurate, non-subjective, concerned with past events.
  
  Semi-structured - some structured and some unstructured.
  
  see chart pg. 11.11.
  
11.3) Management

  Transaction Processing Systems (TPS) - keeps track of transactions needed
  to conduct business.  Features include:
  
  Input and Output - transaction data turns into bills and paychecks.
  For lower management.
  Produces detail reports
  One TPS for each department
  Basis for MIS and DSS
  
  
  Management Information Systems (MIS) - uses data from TPSs to create reports
  Input Output - processed transaction data into structured reports.
  For Middle Managers
  Draws from all departments
  Produces several kinds of reports
  
  Decision Support System (DSS) - a flexible tools for analysis that helps 
  managers focus on the future.
  Input and Output - turns structured reports into high-end, unstructured
  business decisions.
  For Top and Middle managers
  Produces Analytical models
  Components of a DSS: Hardware, Software, Data resources, Model resources,
  People resources.
  
  Examples: Airlines, Real Estate, Geographic
  
  Executive Information Systems (EIS) - Easy to use for top managers, supports
  strategic decision making.
  
  Expert Systems (ES) - Attempts to emulate human knowledge and assist the user 
  in making a sophisticated decision.
  
  Office Automation System (OAS) - combine various activities to reduce the 
  amount of manual effort needed to operate office machines.  Includes things 
  like dictation, filing, copying, fax, etc.  All these things are becoming
  easier due to OAS's.
  
  
11.4) Future - going sideways
  
  The old hierarchical structure is fading away.  Due to new, powerful
  technologies, top progressive managers are allowing employees to have more 
  freedom and power to explore better ways of doing their job.
