Field Study Proposal

Field Study Proposal

• By Carl Rebman

2
Abstract

• To develop a field study that helps to validate
  the theories set forth in the Hirschiem and Klien
  article.
• They discussed four paradigms that essentially
  discuss the relationship between user involvement
  and system development success.

3
Abstract continued

• It is implied that system development success is
  determined by user satisfaction.
• The authors state that out of four paradigms only
  three are in existence.
• Fundamentalism- most widely held and in
  existence.
• Social Relativism - developing systems from the
  end user perspective
• Radical Structuralism - the system developer
  chooses mgmt or labor

4
Hypothesis Testing

• It seems that the way to test these paradigms is
  to set up a test to see if user involvement in
  system development determine satisfaction.
• In this field study high satisfaction equals high
  system development success.
• We can measure productivity and see if user
  involvement increases SD success in that area.

5
Five Models Developed

• MGMT determines system and implements it.
• MGMT determines what systems needs to do
  (objectives), solicits system design suggestions
  from employees, and then builds it.
• Third model same as above except end users are
  part of the entire design process (I.e. approval
  steps)
• End users come up with system objectives but play
  no part in system development.
• End users come up with system objectives and play
  an integral part in development process.

Field Study Execution

• Study would last four- six months in duration.
• A large financial institution bank would be
  selected
• b/c of large IS reliance
• b/c IS change has large impact
• b/c each bank has many branches that can be used
  for survey testing

8
Field Study Execution

• Total of five branches (or branch areas to be
  tested)
• all branches complete survey instrument at the
  beginning of study.
• Branch areas will be tested according to the
  models described earlier.
• All branches would be tested at the end

9
Field Study Execution

• Focus will be on CIS inquiry
• Four Branches will be able to make changes, one
  will stay constant.
• Branch 1 end users will be told what needs to be
  done and input
• branch 2 same as one, except they will see beta
  version before implemented
• branch 3 end users will be asked what needs to be
  changed
• branch 4 same as e except beta version

Sample Size Determination
11
Survey Instrument

• 330 surveys to be conducted (150 in beginning,
  180 at the end)
• most questions taken from Marketing Scales
  Handbook
• also from Error and Bias article

Conclusions

• Still in early development stages
• other avenues that can connected to this study
