The key line -

"Data showed that the top four priorities for HR managers today are performance management, skills and competency management, succession planning, and learning management. At the same time, responses indicate that HR managers believe they have the least amount of expertise in these four functional areas. According to the research, only 35% of organisations have any type of automated performance management system and 58% rely on paper based processes. A significant majority – 68% -- of respondents indicated that integration of learning and HR systems is critical or important to their organisations."

That's the problem of course, with performance and skills management systems.  About 60 to 70 percent of the HR departments, talent agents, etc, simply don't have the time to create these jobs and models.  That's why even when there is an organization that is utilizing a learning management system - and they get some performance and competency management piece as part of the package - studies show that 70% of these systems go unused, or at least vastly underutilized.
