From imagining software to experiencing it before it exists For more than two decades, Agile has transformed the way software is built. Its principles emerged in response to a world where requirements evolved continuously, long development cycles created unnecessary risk, and organisations needed mechanisms to learn while delivering value. By breaking work into small, working increments, Agile enabled teams to reduce implementation risk, gather feedback early and continuously refine their products. Prototyping has followed a similar objective. Long before generative AI, paper sketches, wireframes, clickable mock-ups and interface design tools were widely used to explore ideas, capture requirements and help stakeholders understand a problem before committing to implementation. These techniques have always been valuable because they encourage discussion at a stage where change is still inexpensive. The limitation was never the concept of prototyping itself. It was the cost of realism. B...
