Field Study Proposal By Carl Rebman

Abstract n n To develop a field study that helps to validate 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.

Abstract continued n n 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

Hypothesis Testing n n 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. 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.

Five Models Developed ¶ · ¸ ¹ º 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.

Illustrative Models

Field Study Execution n n 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

Field Study Execution n n 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

Field Study Execution n n 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

Survey Instrument n n n 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
