The Hexagon Discussion and Analysis Tool helps organizations evaluate new and existing programs and practices. This tool is designed to be used by a team to ensure diverse perspectives are represented in a discussion of the six contextual fit and feasibility factors. Program indicators assess new or existing programs or practices that will be implemented along the following domains: evidence, supports, and usability. These indicators specify the extent to which the identified program or practice demonstrates evidence, supports for implementation, and usability across a range of contexts. Implementing site indicators assess the extent to which a new or existing program or practice matches the implementing site along the following domains: population need, fit, and capacity. The Hexagon Tool can be used at any stage in a program's implementation to determine its fit with the local context. It is most commonly used during the Exploration stage: the period when a site is identifying possible new programs or practices to implement. If the organization has an Implementation Team, the Implementation Team can carry out this function for the organization.
