When the Smart Irrigation project landed, the brief came with an assumption baked in: farmers needed more technology, from IoT soil-moisture sensors and variable-rate irrigation to automated pivots that dose water by the square metre.
The problem was that no one on the team, including me, knew enough about the domain to pressure-test that assumption. And the stakeholder pressure to move toward advanced precision-ag tech was strong.
I started with domain immersion. Gemini Deep Research gave me a fast, structured understanding of precision irrigation: the sensor hardware, variable-rate and pivot systems, the research directions, the adoption patterns. NotebookLM helped me interrogate technical papers and sensor research in a way that surfaced the real questions underneath the obvious ones.
Then I went into the field, in a structured way.
First, I interviewed researchers and engineers working on smart sensors and precision irrigation, to understand why the field kept pushing for more tech, what they were trying to solve, and what they assumed about the farmers they were designing for.
Then I ran structured interviews with six farmers, translated them, and processed them into a large-scale affinity diagram and a detailed empathy map.
The farmers were not asking for more technology. They were asking for less. More specifically: systems that didn't add to their cognitive load, that worked in low-connectivity environments, that didn't require them to learn a new interface every season, and that didn't assume a level of technical literacy most of them didn't have and didn't want.
The research changed what got built.
Features that had been prioritised based on technical possibility were deprioritised. The product direction shifted from "how do we give farmers more data" to "how do we give farmers clearer decisions." That brief produced a different product.
That shift happened because the research process was rigorous enough to hold up against stakeholder pressure. The affinity diagram and the empathy map were the evidence.
