Information Management
Information Technology Management from 1960-2000
By Richard L. Nolan
- IT ( Information Technology. Digital convergence in data, voice and, video
- new functions were continuously assigned to the computer due to organizational learning
- IT became an information revolution that changed the way companies worked
Stages Theory of IT Management
- Four stages of organizational learning on an S-shaped Curve
o Stage I: Initiation ( proving the value of the technology
o Stage II: Contagion ( - high learning -Technology spreads in uncontrolled manner
o Stage III: Control ( control to slow growth to a manageable
rate
o Stage IV: Integration( balance between control and growth
Three eras of IT
[pic]
Technological discontinuity ( conflict between the old and the new technology
- Managers of the “old era” struggled against those preferring the new technology
- The new technology won
- IT workers faced a “diet of continuous change”
Relationship between Organizational Structure and IT Architecture
- 1960’s -1970’s: M-Form the dominant structure.
- each operating unit would have a hierarchy of line and staff functions
- Mainframe reflected this structure
- Two types of customers for computers:
o Engineers and scientists (scientific computing) (dominant 50’s-70’s)
▪ Help in conducting research& design and manufacturing
o Managers and administrators (commercial computing) (from 70’s dominant)
▪ Data processing (paying payrolls& keeping track of customer payments (lots of input and output data)
The data processing era
- sophisticated information and communication systems supported the mgmt of the larger organizations
- accounting and budgeting systems assured resource allocation
- large-room-sized
