Cognitive science (Cognitive ? and ergonomics,
HCI, Human Factors)
Distributed cognition (Situation awareness,
cooperation, coordination, standard rules vs.
work practice)

Problem
Business models change in reaction to the outside
world Therefore, business goals and
work processes change Process control systems
become outdated even before release This costs
time, money, effort, and anger
6
Business model
Public service? Serves general public No break
even
Commercial? Serves itself Beyond break even

Aim
  • Can we make up a system structure that can
    handle changes in business goals and work (i.e.
    control) processes?

To this end we need to isolate the factors that
remain stable throughout the process of change
10
Examples of goals
Personal concerns Group concerns
Get an exciting job
Help juvenile delinquents

Examples of control process applications
Accuracy
Speed

Theory
Evolving business models cause shifts in personal
and business goals They also affect the speed
of control processes and thus, (human)
accuracy All this explains the changes in system
requirements
13
Where, then, can we find the stable factors?
Business goals - break even / make
profit egotistic - to serve and
protect altruistic Personal goals - make a
career egotistic - commitment to
company altruistic
New business model changes priorities

Prospects
  • Ethnography
  • Structured questionnaires
  • Confirmative factor analysis
  • Model fit
  • Adaptive system structure?

19
  • Ethnography
  • Structured questionnaires

Items are derived from ethnography
20
Examples of items
Multiple passwords are important to company
security
Multiple passwords are impeding manual data input
The new sequence controllers are trivial with
respect to working efficiently
The new sequence controllers are helping me to
get a promotion
21
  • Confirmative
  • factor analysis
  • Model fit
