The participants whose stories informed the research were senior-level executives ranking from the level of director and above. The participants ranged in age from 38 to 73. The goal was to interview between 20 and 30 participants until the point of saturation was reached (Creswell 1998) and no new interpretative patterns emerge. 31 executives were interviewed and 28 of the interviews were utilized in this study. One of the 31 was eliminated due to his high public profile and concern as to whether his data could be kept confidential. Two others were eliminated after their interviews had been conducted and it was clear that they did not see themselves as having the power to make decisions that impacted their organizations and therefore no longer fit the selection criteria.
