Case 01
Replacing the automatic commentary I had approved for the wrong room
In 2017 I approved a proximity-triggered feature intended to begin commentary as a visitor approached an exhibit. It made the demonstration feel effortless. During twenty-four walkthroughs, however, fifteen starts matched the intended object and nine began an explanation associated with another room. The guide could sound authoritative while pointing attention away from the object the visitor was actually examining. I had accepted the convenience claim without enough evidence about that relationship.
The engineering sponsor proposed further tuning before changing the interaction. Arun's field notes showed that visitors often tried to reconcile the unexpected explanation with what they could see, rather than immediately deciding the guide was wrong. That was a more serious product problem than an inconvenient start. I supported a ₹31 lakh change to visitor-confirmed object identification, using the venue's visible identifiers and an explicit selection before playback. We accepted an extra action and revised the launch demonstration instead of claiming that further tuning had already solved the positioning problem.
The team separated object choice from commentary playback and provided a way to return to identification when the selected object did not match. Venue colleagues checked the identifiers used in the guide. The twenty-four-walkthrough result remained fifteen intended starts and nine mismatches; we did not rewrite it as evidence of improved positioning after a different interaction was introduced. The product now asked the visitor to confirm the object rather than silently making the same inference. That was the outcome we could support, not a claim about the accuracy of a technology we had not established.
I owned the original approval and the cost of changing it. The enterprise gave up a striking automatic demonstration for a more defensible visitor interaction. I would now test the meaning of an incorrect start much earlier, including whether people notice and recover from it. An extra tap is not inherently good or bad. Its value depends on whether it establishes something important that the service otherwise only assumes. In this case, the pause helped keep the visitor's attention connected to the object rather than to our confident mistake.
