The toolkit begins with an overview of the Service Planning approach and proceeds with chapters on each of the four tools. Discussion of each tool includes sections with general guidance, a review of the tool in practice, and templates and additional materials. The step-by-step processes and templates outlined in this Toolkit represent a best effort to provide resources that will work for all Hubs in most cases. While the tools provide guidelines based on best practice, they should be adapted to local contexts and the planning requirements of each service. Where relevant, the Toolkit offers additional resources to assist Hubs in refining their approaches
