From our experience, challenges often include the impact on people and planning for team adoption of changes. Additionally, resource availability is critical, especially internal Subject Matter Experts (SMEs) who are essential for successful implementation.  However, they also maintain their regular roles, making backfilling during implementation challenging for customers. Furthermore, communication is a common hurdle; the internal Executive Sponsor must strategize to ensure progress and challenges are communicated throughout the organisation, as this work spans beyond just an IT project.
