Identify at least one significant contract administration challenge (threat to contract success) potentially associated with contracts for each of the following categories of services: Internal support services (for example, HVAC maintenance and repair), Services delivered to the public (for example, refuse collection or public safety), Design services (that is, architectural and engineering services), and "Other" professional services (for example, services provided by an attorney or a doctor).

To the extent you can, identify a challenge for each category of services, which although not necessarily unique to that category of services likely would not be a potential challenge in all categories.

Explain how you would seek to avoid, mitigate, or otherwise address the potential challenge you identify for each category through contract administration or contract management practices learned in the course. Please include in-text citations for each
