What is Participatory Prototyping?

Participatory prototyping is an approach to intervention development combining theory-informed intervention design with a process of iterative optimization led by end-users. An initial intervention design can be optimized through multiple rounds of participation followed by iteration. 

1

Diagram theory-based intervention components as a process

2

Specify adaptable components and optimization criterion

3

Operationalize each component to produce initial “prototype”

4

Deliver prototype in rounds of 8-15 end-users or clusters

5

Collect intercept interviews with end-users.

6

Provide bullet-point summaries to implementers.

7

Use Nominal Group Technique (NGT) with implementers to generate and prioritize adaptations, deletions, or additions.

8

Repeat in rounds

More on Nominal Group Technique (NGT)...

NGT is a structured process for

  • generating ideas 

  • prioritizing ideas 

  • reaching consensus among diverse stakeholders

NGT gathers information by asking individuals to respond to questions posed by a moderator, and then asking participants to prioritize the ideas or suggestions of all group members. The process prevents the domination of the discussion by a single person and encourages all group members to participate.
