Who made IngaBoard

IngaBoard is a passion-driven project built by a solo developer based in Tokyo, Japan. My professional foundation is rooted in Health Services Research (HSR), where I spent years leveraging statistical causal inference and the precise framework of Directed Acyclic Graphs (DAGs) to disentangle complex relationships in data.

Through applying these analytical frameworks to the realities of quality management, I realized how powerful DAGs can be for structuring and clarifying the causal chains we encounter in the real world. By harnessing the engine of Graphviz to create a streamlined, visual language, I found a way to bridge the gap between rigorous analytical methods and the nuanced, often messy reality of complex challenges.

I designed IngaBoard to address a fundamental mismatch between the demands of structured causal analysis and existing software. Currently, practitioners are forced to choose between two extremes: tools that are prohibitively complex—demanding high IT literacy—or those that are too generic. PowerPoint, for example, is widely used for incident reporting, yet it treats causal diagrams as "one-off" sketches rather than reusable organizational assets. These existing solutions were simply not optimized to capture the subtle, structural nuances of failures, often hindering teams from scaling their causal thinking effectively.

I built IngaBoard with a broader mission: to democratize the quality of decision-making. I believe that structural thinking should be a primary, reusable asset—intuitive, distraction-free, and scalable across any organization. By removing the friction between thought and visualization, I aim to transform structured, causal analysis into a standard, accessible skill for everyone. My goal is to ensure that deep systemic insight is no longer the exclusive domain of a few specialists, but a shared foundation for safer, more resilient organizations everywhere.
