What principle is NOT part of the NIATx process improvement model?

The principle that is not part of the NIATx process improvement model is rooted in the methodological approach of NIATx itself. This model emphasizes iterative, incremental changes aimed at improving service delivery in addiction treatment. Key components of the NIATx model include identifying and addressing key problems, actively seeking outside perspectives to inspire innovation, and ensuring that changes are monitored for their impact.

While measuring the impact of change is essential for evaluating the effectiveness of any process improvement initiative, it is not explicitly outlined as a central principle specific to the NIATx framework. Instead, the focus is more on creating a culture of change, leadership involvement, and a community of support to drive improvements rather than solely on the metrics of those changes. Hence, the inclusion of elements like fixing key problems, leveraging encouragement from outside, and leadership in implementing change reflects the model's intention to transform systems holistically rather than just through quantifiable metrics.
