Changes and new ways of working will take time to get right. You should anticipate challenges along the way. It takes time and effort to embed successful change. Be mindful to acknowledge loss and celebrate opportunities as well as celebrate new beginnings. This may include building relationships in a new team and provide training, development and support to staff whose role has changed.
Take the time to review the change process, to acknowledge what went well and what could be done differently in the future. Continuous improvement and iterations are normal components of embedding real change, so anticipate and build in appropriate reviews and on-going communications or support as you progress.
