This paper builds on previous theory and research on strategy and human resource management to identify important linkages between the firm's strategy, its human resources, and performance outcomes. First, we review the relevant literature focusing in particular on the role of human resources in creating competitive advantage. We then present a multi-level model illustrating how human resource management practices can effectively align organizational, group and individual factors with the organization's strategy. We redefine line of sight as the alignment of organizational capabilities and culture, group competencies and norms, and individual KSAs, motivation and opportunity with one another and with the organization's strategy. Further, we propose that such alignment contributes to the creation of human capital and social capital, both of which are necessary to achieve and sustain superior performance. We conclude the paper with some implications for future research and practice.
