- - - - Without non-IT managers' contributions, strategic consequences escape firms' radar screens
        -Otherwise choosing to delegate to your IT unit
        -Can make IT catalysts for competitiveness

        Data Architecture
        
        Data architecture answers one question: Where is your firm's data stored ?
        
        Integrated firm-wide data is the foundation of IT- enabled automation of business processes and large-scale business analytics. However, the prevalent problem in firms is proliferation of duplicated and inconsistent data.
        
        This problem is caused by the dispersion of a firm's data
        a) across apps
        b) across geographic locations
        They require different fixes
        
        Apps are software programs that undergird the functionality of a hardware device such as a PC, smartphone, tablet, cash register, or other Internet-connected devices
        
        For example: a thermostat, camera, or car systems
        
        Such devices (called clients) are used to access a resource or service placed on a more powerful central computer (called a server).
        
        One server machine can serve many user devices, which connect to it through the internet
      - IT infrastructure is your firm's digital plumbing - its firm-wide foundation of shared IT assets and IT services used by all line functions
      - It includes the networks through which data travels and apps are linked and the hardware on which apps run and store data
        
        For example: computers, tablets, servers, and storage devices)
        
        IT infrastructure architecture is their firm-wide arrangement
    - - Balances economical performance today and economical changeability later
      - Fulfils today's requirements but plans for tomorrow's expectations
      - Explains why some:
      - -firms; IT is more adaptable archrivals'
      - -can harness new innovations faster
      - Non-IT managers can help preserve enough of both
  - - - However, IT architecture lurks in the spot of non-IT managers because they perceive it as a technical decision best left to IT specialists, who are unschooled in its strategic consequences. The resulting choices an constrain strategic flexibility tomorrow.
