The correct response highlights a significant challenge that agile teams encounter when integrating with Procurement processes. Agile methodologies emphasize flexibility, rapid iteration, and responsiveness to change, which can contrast sharply with traditional procurement processes that tend to be more rigid and bureaucratic.

This rigid structure can hinder the agility of teams that need quick access to resources, services, or tools in order to deliver value iteratively and respond to changing requirements.

Agile teams thrive on collaboration, rapid feedback, and adaptation, which can be effectively stifled by procurement processes that are not aligned with these principles.
