What is your experience implementing network infrastructures? When doing this, what are some of the challenges you encounter?

"I have worked with my organization's network support team to integrate their topology with the IT infrastructures I supported. We frequently encountered challenges when integrating a network infrastructure. These involved issues including a lack of resources, a conflict between the various systems we are implementing, and maintaining an organization's productivity during the implementation. Due to our experience, we anticipated many of these challenges and addressed them effectively, using standard industry practices."
