The key barrier is language and the use of acronyms. In cross-functional, international, or virtual teams, communication challenges can hinder collaboration. Procurement often uses specialised terminology and acronyms that other functions or non-native speakers may not fully understand. This can create confusion, misalignment, and inefficiency.

Geography is less of an issue in virtual teams, as digital platforms enable collaboration across locations. Time and cost can be challenges, but the study guide specifically identifies language and acronyms as barriers.

Effective category managers overcome this by using clear, simple communication and ensuring shared understanding of procurement terms. This reduces misunderstandings and ensures that all team members---finance, engineering, operations---can contribute effectively.

Cross-functional teamwork is central to category management success, but only if barriers to collaboration are proactively addressed.
