The purpose of this chapter is to explore the issues that relate to the under representation of women in leadership roles in high-tech companies. This is a broad issue that covers the development and education of young woman in the field of technology, the issues that related to difficulties in selection, promotion, and finally, retention issues. To help structure the chapter the authors use Schneider's Attraction-Selection-Attrition Theory introduced in the seminal article “The People Make the Place” to examine the facets of this issue. The authors conclude with recommendations to improve representation of women in STEM technology.
