Intro to Integrated Enterprise Information Systems
Show Answers:

  1. Define IEIS - Integrated Enterprise Information Systems. 
    "Official class definition"
    Joint communication channels of an organization
  2. What is IEIS?
    Joint communication channels of an organization
  3. Enterprise
    An organization/business. An industrious effort, especially one directed towards making money/common goal
  4. Information System
    • --A system of interconnected channels for communicating knowledge of specific events or situations (just a tool)
    • Any paths by which enterprise employees & business partners receive info
  5. Integrated
    -- joined together.
  6. TEXTBOOK/slide IEIS definition, not class definition
    An integrated enterprise info system is a set of communication channels in a business organization combined together in such a way as to form one network by which info is gathered or disseminated
  7. Information reliability requires:

    • Accounting independence
    •    - Decision makers in these functions require that vital info be applied by an independent party to ensure integrity.
  8. The goal of an information system is to support:
    • The stewardship function of mgmt
    • mgmt decision making
    • The firm's day to day operations
  9. IS vs AIS vs MIS slide
    • AIS includes accounting info like general ledgers, fin statement info, TPS, MRS
    • *
    • MIS = management info systems
    • Includes Fin, mktg, prod, HRS, & distro. 

    More on the functional side of the day to day business?
  10. Data
    Raw facts. We collect data in our system. Data is not in a useful format yet.
  11. Information
    Information is data that is relevant or useful to the user. INFO IS USEFUL!

    It puts the data into context. Data processing is how we turn data into info.
  12. How do accountants get lots of their data?
    Source documents. Accountants process,& they become reports/fin stmnt which either go to external users or internal (end) users
  13. What are the (4) functions for transforming data into info according to the general AIS model?
    • 1. Data collection
    • 2. Data processing
    • 3. Data mgmt
    • 4. Info generation

    There are fin and managerial subsystems (see AIS vs MIS slide) but they all feed into and are a part of this.
  14. Integration can only be achieved in one way
    No. Integration can be achieved/assembled in many ways and in varying degrees.
  15. A recognized problem in integrating enterprise info systems is that:
    Siloed Operations lead to Siloed Systems and siloed systems perpetuate siloed operations.
  16. Siloed operations
    • Isolation of functional areas
    • Like siloes, only at the very top does anything flow back and forth between siloes. Walls=no pathways of communication between siloes. 

    - in enterprises, departments could be siloes.
  17. How do siloed systems perpetuate siloed operations
    When decision making is based on info obtained from within one functional area, those decisions are likely to be made from narrow perspective
  18. Why re-engineer siloed systems and operations?
    For one: Recognize that most enterprise workflow processes are cross-functional and that passing info from one department to another in a non-integrated environment takes time.
  19. Some re-engineering efforts have focused on:
    consolidating disparate info systems to eliminate duplication of effort in collecting, maintaining, and reporting info.
  20. REA (general)
    • Resources*Events*Agents
    • An alternative accounting model. Has been expanded into an enterprise domain ontology.
  21. What is the premise of REA?
    Premise is that base objects (foundational building blocks) shouldn't be reflective of a certain view, but should reflect the real underlying activities in which the enterprise engages.
  22. REA ontology approach:
    Attempts to eliminate all silos  and is based on a set of building blocks that could be used by all enterprises and by all functional areas w/in an enterprise
  23. Most failed ERP software issues have been blamed on:
    People issues
