"In order for an organization's diversity strategy to succeed, it must be clearly and inextricably linked to the organization's purpose and reason for existence.  For while social justice is a noble and worthwhile cause, a sense of righteousness alone will not propel an organization forward with regard to its diversity commitment – as long as the organization has another mission. 

Each organization must look at every stakeholder -- its vendors, potential employees, current workforce, investors, partners and customers -- and consider how the organization might benefit from understanding the impact that its practices have on people who possess different life experiences and points of view. Whether a for-profit organization or not, everyone has a mission.  This is what some might call understanding the bottom-line on diversity as it relates to that mission."
