This second major part of the text is concerned with the micro, individual level of analysis of organizational behavior. Recent workplace research by The Gallup Organization has led to a new management metric known as HumanSigmaTM. This is a measure of "the human difference" and is made up of two complementary economic factors, known as employee and customer engagement. Together, these factors assess an organization's success in managing the Emotional Economy and driving financial performance. HumanSigmaTM is a reliable indication of how organizations manage and leverage employee and customer engagement and productivity. It is a new way of thinking about how human differences interact. At the same time, it is a process, or sequence, of activities to leverage this human difference. Finally, it is a metric that indicates how well companies are progressing in the deployment of their human difference. Because there is significantly more HumanSigma variance within companies than between companies in the same industry, it is most effectively measured and managed at the work group level, one employee and one customer at a time. Successful management of these metrics
requires the active involvement of local managers and associates. The Gallup PathTM, the sequence of linkages between human performance and financial metrics including revenue, earnings, and stock value, further explains the components of HumanSigmaTM management. Curt Coffman and Gabriel Gonzalez-Molina further detail this discussion in their recent business book, Follow This Path (Warner, 2002).
