INTRODUCTION
RESEARCH DESIGN
The research design used the total design method by
Dillman (1978)
to develop and pretest survey questions, develop the format of the survey and sequence of questions, and construct the cover letter.
the administration of the completed survey (including contracting companies, mailing the survey, and following up with non respondents) omitted the follow-up contracts recommended by Dillman. These follow-ups were omitted due to funding restrictions.
DATA COLLECTION
Data collection was conducted as a three-step process.
First, an initial group of firms was identified.
Second, a data collection instrument was designed and pretested.
Third, the final survey was mailed to a rondom sample of executives.
