Field Study Proposal By Carl Rebman

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

Abstract continued n It is implied that system development success is determined by user satisfaction. n 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

Hypothesis Testing n 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. n In this field study high satisfaction equals high system development success. n We can measure productivity and see if user involvement increases SD success in that area.

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) ¹ End users come up with system objectives but play no part in system development. º End users come up with system objectives and play an integral part in development process.

Illustrative Models

Field Study Execution n Study would last four- six months in duration. n 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

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

Field Study Execution n Focus will be on CIS inquiry n 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

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

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