A long term implementation plan creates a path to achieving desired outcomes of adopting the selected approach. Activities at each level of the service system are necessary to assure desired practices are supported and maintained, including infrastructure changes at state and regional/district and local levels, and T & TA capacity necessary to provide and sustain needed training. Funding plans need to address both start-up costs of implementation, as well as continued costs of sustaining the desired approach. The most important task during this stage is to create an implementation team, with consistent leader(s) and membership, which can develop the plan and oversee implementation. This team needs expertise in both the desired service delivery approach and implementation science.
