Three sources of guidance for selecting intervention strategies:

What are "best practices", "best experiences", and "best processes"? How are they different?

Best Practices: Intervention recommendations based on a careful analysis of many research and evaluation studies that support the intervention's effectiveness.

Best Experience: Intervention tactics utilized in previous or current programs that have not been subjected to rigorous study and assessment and hence fall short of best practice standards.

Best Processes: Planners construct original intervention plans based on their knowledge and abilities of effective planning processes, such as including individuals in the priority population and using theories and models.

The difference between the past definitions is that best practices are the most recommended because it has been tested to work while best experiences with best evaluation plan but not positive results and best processes are just ideas that could either work or not.

Step-by-step explanation

Best practices, uses  interventions that have undergone critical review of multiple research & evaluation studies

Best experience, fall short of best practices but show promise

Best processes, original interventions based on theory
