You may differenciate from a more organizational, more political and a more financial perspective. Following these three dimensions, you may think about actors related and structures and processes affected...

Limitations can be due to the implementation process, particularly "the sense-making" of policy. Implementing agents have to make sense of policies of infrastructure projects which draw on on an individual's knowledge base, beliefs and attitudes. Infrastructure project governance challenges and limitations in developing countries might thus be as a result of interpretation issues. Read Spillane, J. P., Reiser, B. J., & Reimer, T. "Policy implementation and cognition: reframing and refocusing implementation research" for more information on how cognitive factors play a major role in policy implementation.
