• Why do organizations build IS?

  To improve their efficiency and effectiveness

• First order change: (process <-> technology)

  • Influences the technical system
    
  • Occurs when a new IT is introduced that modifies how an existing process is performed
  • Easiest to manage

• Second order change: Informate (people, tech, process)

  • Influences the people component
    
  • The way individuals perform processes and the manner in which they interact with the technology change
  • Key challenges:
  • • Try to overcome the human tendency to resist change
    • Provide appropriate training

• Third order change: Transform (All)

  • Influences the structure component
  • Technology -> a change in the way the organization selects, uses and manages technology
  • People -> a  change in the reporting and authority structure
  • Process -> a novel way of task accomplishment or a new set of task
  • Most challenging (much managerial involvement)

• 2 Lecture 2: EIS architecture

• What is EIS architecture?

  High-level blueprint of an EIS (including the relationship between all IS components of IT, people, process and structure) that serves to understand its internal structure to aid in its design, redesign, configuration and maintenance.

• What are the typical styles to represent EIS architecture?

  • Columned style: Defines the structure of the EIS by organizing functionality into several functional ‘subareas’ (the columns) at the same level of functional abstraction. E.g., HR, finance, logistics, …
  • Layered style: Defines the structure of the EIS by organizing functionality into several layers of abstraction. E.g.: 4-tier, 3-tier or multi-tier in general.
    
  • Component-Oriented style: Defines the structure of the EIS by grouping coherent application functionality into components with explicit interfaces. E.g., Service-Oriented Architecture – SOA, Object-Oriented, …

• Tier 1: Data logic

   Contains the database for storage of business objects and the logic that implements the basic operations on the data that is used by the function logic tier.
   The data access logic implements the basic data operations on the business objects

• Tier 2: Function logic

   Handles individual business functions that an EIS supports. This includes related business rules and data validation. Almost all functions are derived of CRUDL operations (create/read/update/delete/list)
