This practical guide was developed following a three step-process including an evidence review,2 consensus development and public peer review. The practical guide was developed by TDR Global members in partnership with SESH and SIHI.

The evidence synthesis included a global scoping review and qualitative synthesis of the evidence.2 The evidence synthesis was written by the core team and received feedback from the 12-person working group. Each working group member had experience with LMIC public engagement or crowdfunding. They included academic researchers, development experts, social innovation leaders. Eight of the 12 members were living in LMICs. An end user group of 14 individuals with a health, social innovations, or public engagement background was solicited for the co-creation of this guide in order to gain a diversity of perspectives on its use and implementation. Twelve of the fourteen members of the end user group were living in LMICs. All participants declared no potential conflicts of interest.

The consensus process included a Delphi survey to incorporate comments from both the working and end user groups. Multiple virtual meetings were organized to discuss the feedback.

The groups iteratively improved the document based on written feedback and videoconferences. Within the executive summary, all statements that received greater than 90% agreement were included in the final version.

A public peer review process was organized by calling for public volunteers to become reviewers for the guide. The call for public reviewers was shared on social media and disseminated across TDR Global, SIHI and SESH networks. Six public peer reviewers from Nigeria (4), Sri Lanka (1) and Colombia (1) provided feedback.

The core team made final revisions to the document incorporating contributions from final meetings and discussions.
