This study investigated the experiences of African American/Black, Asian American, Caucasian American/White, and Latina/Hispanic American women who advanced from operational or technical IT roles to senior executive IT roles. The intent was to understand how individual and organizational factors influenced the women's career advancement journey and what role, if any, gender, race or ethnicity played in the journey. Advancement research that solely focuses on gender, race, or ethnicity provides an insufficient and limited examination of women's advancement journey. Rather than treat gender and race or ethnicity as mutually exclusive categories of experience and analysis, this study approached the topic from a gender intersectionality perspective and used the individual differences theory of gender and IT as an analytical lens. As a result of the analysis, six themes emerged: pathways to the senior IT executive role, informal networks, bias, credibility and legitimacy, the importance of support, and the importance of technical skills. Although some findings support existing research on women's career barriers, the intent was not to generalize the findings to all women. Rather, the study's results demonstrate that racial and ethnic variations among the women in addition to a variety of other factors contribute to different career progression experiences.
