With regard to public management network theory development, among the most important issues that remain is a recognition of the limitations of networks. Networks often find reasonable solution approaches, but then run into operational, performance, or legal barriers that prevent the next action step. Networks face challenges in converting solutions into policy energy, assessing internal effectiveness, surmounting the inevitable process blockages, mission drift, and so on. While research on network management continues unabated, it is necessary to consider how networks are limited and challenged, and how/when these limitations can be overcome.
