The most frequently used quantitative measurements of system effectiveness are the organization’s ability to fill key jobs with internal candidates, rather than outside hires; ethnic and gender diversity in promotions; reten- tion/attrition rates; and positive job evaluations follow- ing promotion.
Qualitative assessments tend to be based on issues such as the participants’ transition experience into their new role, the quality of their preparation beforehand, reasons for attrition, and qualities of bosses in develop- mental assignments.
