Impact of Technology

Does IT matter?
 Is IT harmful?
IT for Strategic, Competitive
Advantage





How to measure impact of information technology
on productivity and performance? ROI,
Performance, sales.
IT for strategic competitive advantage gives
unique edge over competition
Sustained edge over competition
Examples: Baxter Healthcare, American Airlines,
Walmart, USAToday, Comdial, FedEx, Otis
Elevator
Increase in productivity, or increase in worker
hours?

Systems Planning

IS plan maps to the corporate strategic plan
 Variety of IS planning styles: CSF,
Enterprise, other formal structures
 Plan itself: What are the components?
 Organizational change from systems:
TQM, BPR, paradigm shifts or simple
automation?
Strategic Advantage: IT at
work


GPS is the root technology for GIS applications
GPS is operationalized via satellite constellations,
geostationary and low orbit satellites
m-commerce rests on GPS
GIS is important new business application
Encourage further study with ArcView or GIS
classes in Geology or elsewhere
How does GPS work in
general




Constellations of at least 24 satellites operated by
DOD
Removed selective availablity
GPS satellites radio down data packet every 30
seconds, with pseudo random bit pattern
Calculates signal delay differences
Uses how long signal took to get to receiver,
satellite’s velocity, and time of transmission and
triangulates three signals or more to pinpoint spot
Fairly reliable unless under canopy or in unusual
regions
How does the device work

Terms
 Maps
 Menu
 Acquiring satellites
 Establishing location
 Marking position and viewing in map page
 Compass page, map page, highway page
Why is GPS so interesting

For a long time, man only knew latitude based on the stars,
and ships were lost and wrecked
Progress was made with determining longitude when
clocks helped to establish locations based on celestial
relative to the earth at certain times (required expert
seamanship, accurate charts, sextants)
Polar magnetic fields shift daily
Now, can get 3 meter accuracy
Get latitude, longitude and altitude with high degree of
accuracy and little amount of skill
Predict will radically change the world that we live in
technologically
