Work with no visible emergency

Text A: an original contemporary practice extract.

At the holiday plant-care rota, my neighbour looked at the daily watering notes and said nothing much seemed to have happened. That was largely what we wanted. Before the owners left, we had checked which plants needed attention on which days and who would hold the key. The notes then recorded ordinary visits rather than frantic messages about a locked door.

One person could not make a visit, and the named replacement took over without a new round of calls. We changed the rota and continued. I did not claim that every plant would have been lost without our arrangements. Their value was more modest: they reduced avoidable uncertainty while people were away. An uneventful record could show the plan being used, rather than prove that planning had done nothing.

Text B: an original contemporary practice extract.

The stage crew prepared a spare set of batteries and agreed who would collect them if a microphone failed. During the concert, none did. A performer joked afterwards that the labelled box had enjoyed a quiet evening. The crew member beside me said its quietness did not tell us whether preparing it had been foolish.

One assistant had left early, so another took the agreed standby place. Nobody interrupted the performance to discuss it. The spare batteries returned to storage unused, with a note to check the box before the next event. We had not created a dramatic rescue to prove the arrangement mattered. It made a response available, while leaving us free to be pleased that the concert had not needed it.
