This tool provides a process for describing and further assessing propositions, which are proposals on best practice that have a solid evidence base but remain contested. As part of their project on ‘Food System Innovation for Food Security’, Rodriguez and colleagues argued that evidence can be divided into three categories: axioms, propositions and observations. These are defined as:
- “Axioms: (close to) self-evident truth
- Propositions: proposals on best practice that have solid evidence base but remain contested
- Observations: things that stand out from review of evidence but where implications are unclear”.
They also outline a process for describing and further assessing propositions. Propositions are presented in a two to four page format, divided into the following sub-sections:
- “Statement of the proposition: a single sentence statement of best practice about an aspect [of an intervention]
- Explanation: a single paragraph expansion on the proposition
- Evidence: summary data and references supporting the proposition derived from interviews about the projects analysed and documented material accessed
- Example/s: narrative from case study project [intervention] illustrating the proposition
- Consequences for the area under investigation [food security for this project]: hypothesised consequences of the proposition for [intervention] outcomes
- Project design considerations: implications of the proposition for project design in … development interventions
- Assumptions and their implications: assumptions about causality, assumptions about strength of evidence, assumptions about scalability and context
- Counterviews and their implications: other experience suggesting different conclusions.”
“Propositions can provide a concise and aggregated source of [intervention] information for consideration in project design and as a resource to promote discussion and learning. The aim of the propositions is to provide a platform for discussion and debate rather than a fixed set of lessons learned.”
