This document discusses international development projects and their use of theories of change (TOCs). It mentions that TOCs can track how projects contribute to development goals over time and sectors like agriculture, water, economic development, and governance. Maintaining and comparing versions of TOCs to project proposals allows assessment of whether proposals meet requirements and how to incorporate lessons learned. Relationships between nodes in TOC network versions can be represented using relation nodes to better connect relationships over time despite Neo4j limitations.

Sectors:
• Agriculture
• Water and sanitation
• Economic development
• Good governance
Case: International development projects
Stakeholders
• Population
• Governments
• Private sector
• Funders
Challenges
• Complex and changing environment
• It’s about behaviour of people, it’s not science
• Decreasing public support

3. @tomzeppenfeldt @ophileon
• Who is involved in development and which path leads to development?
• How do projects contribute to development?
• Do project proposals fulfill requirements?
• How to incorporate lessons learned and new insights?
• How to justify project spending against “old” logic?
Typical questions

Projects contributing to development

6. @tomzeppenfeldt @ophileon
• Keep track of versions of Toc
• Compare project proposals with Toc
Focus for now

7. @tomzeppenfeldt @ophileon
Two network versions

Inserting relationnodes

9. @tomzeppenfeldt @ophileon
Pros and cons of relationnodes
Pros
• Neo4j doesn’t allow relationships between relationships and nodes, but I
need to connect relationships to versions / persons / periods / aliases which
are represented by nodes.
• Less “opening” of relationships. Better rely on traversals.
Cons
• Additional abstraction layer.
• Vizualisation more complex. Some tweaking required
