What I study:Find Interesting People
Help Biologists Understand Data
Systematically controlled IT functions aim to assure that IS: Provides value, Pushes the envelope, and Mitigates risk
Business As Usual
Management Inattention
“We’ll write the documentation later”
“We won’t get hacked, we’re too small to be on a hacker’s radar”
“Pick the best solution for our department”
Scale and costSOX Compliance
Threat vulnerabilityIncreased IT dependence
IT’s role in organizational change
“There’s no real need for a log file”
“It will be plenty fast”
“We’ll delete that old user ID later”
The Bad News: 72% do not!
28% of large-scale IS projects “succeed”

Modeling Systems Models represent and communicate
facets of a system: Function: What is accomplished? Structure: How is it constructed? Behavior: How do the parts act and
interact?

Organizing Data for Analysis
A retail store manager hears reliable information from one of her employees that diaper sales in their store has been highest on Fridays. Assume this statistic was based on data that was collected during the last quarter.
What would you do if you were that retail
store manager?

You can’t invest in IT well, if you don’t understand what you are buying.
MIS can help an organization gain Competitive Advantage
Farmers: Why would they sell to us?$$$, AND we provided web access to their data
Cotton Mills: Why would they buy from us?$$$, AND our software adapted to their specific needs
Competitors couldn’t match our efficient operations: Optimized selection of which cotton bales to load together helped us “scratch nickels out of the dirt! “

IS: Success or Failure? Recipe for success: What types of
knowledge are needed to be successful?
Successful IS in business require development team to have a well rounded set of perspectives
• Organization/Business functions• Information Technology • People
The situation: Many information workers,
Lots of technology, but …
Effective systems to support organizations & people (including customers!) are not always available.
Organizations need help!!!
Is this reflected in the Job Outlook for the IT industry?

Display Data Effectively
Document collections can be organized (grouped) based on the ideas they contain. Voronoi Diagrams help display these groups in smooth proportional shapes: users can better understand an information space.
