Qiao’s list began with five beds and ended with a name written in the margin.
She sent Yanchuan a photograph without patient identifiers after obtaining permission to share the form as an example of a scheduling problem. The hospital had introduced a new worksheet for coordinating nonurgent transfers during night shifts. The system ranked likely discharge times and proposed an order for moving patients between wards.
“Why the handwritten name?” he asked.
“Because the system doesn’t know the family hasn’t arrived.”
The patient was medically eligible for a move, but there was no safe place to send her until a relative brought the equipment she used at home. The transfer timetable had treated a clinical decision as the entire decision. Qiao and another nurse had kept the bed occupied and left the margin note so the morning team would not undo the exception.
“Did somebody correct the model?” Yanchuan asked.
“We corrected what we did,” she said. “The model can be somebody else’s problem once the patient is safe.”
He almost launched into a description of the factory pilot’s audit log. Qiao had just worked thirteen hours. He asked when she had eaten.
She laughed. “So you’re finally learning the order of operations.”
On his next visit to Guangzhou he met Qiao at the hospital canteen between shifts. She had a paper cup of soup and a stack of printed forms. The patient transfer tool was still a trial. Staff were instructed to record why its suggestions were declined, but the drop-down choices were too narrow: medical delay, bed unavailable, transport unavailable. No choice described a relative unable to come until morning.
“Could you write other?” Yanchuan asked.
“You could. Then the morning administrator asks which standard reason to put in the report.”
He read the instructions. A small sentence beneath the form said that exception rates would be reviewed as part of ward efficiency. He could imagine how much pressure sat inside that harmless word.
“Someone wants the exceptions to go down,” he said.
“Of course. We do too. But not by pretending patients are boxes we can stack earlier.”
She pointed at her handwritten margin. The night list did not merely record a deviation. It carried responsibility from one shift to the next, naming the person who had accepted the delay and the person who needed to check again.
At the factory pilot, Gao had demanded similar handovers. Yanchuan asked whether he could show Qiao’s blank form, without any hospital information, to Ning as a design example. She agreed after reminding him not to treat her ward as a sales opportunity.
The following week Ning visited the factory’s night team. Their recommendations were often declined for reasons that did not fit the software categories. A technician kept a private notebook of equipment waiting for spare parts. A production worker knew which batch could not safely tolerate a short stop. The system had been unable to see either constraint.
Instead of adding a larger list of guesses, Ning proposed a field in which operators could identify a reason and assign a follow-up without exposing unrelated personal information. The changes would require review before the recommendations were retrained.
Guo thought a free-text field would make the data difficult to summarize.
“Yes,” Ning said. “The work is difficult to summarize.”
He looked at the records for a long time. Then he asked what it would cost to preserve the human notes and protect them from being used as employee performance scores.
Yanchuan had no ready figure. He was pleased that Guo had asked for the cost rather than simply removing the condition.
That night Qiao called again. She wanted to know whether the factory was now going to save money by keeping better notes about problems.
“Perhaps,” Yanchuan said. “But the benefit needs to include what staff don’t have to repeat between shifts.”
“That’s a benefit to the next person. It’s not always a benefit to the manager buying the system.”
He wrote her sentence in his notebook, crediting the idea to a nurse rather than claiming it as an engineering insight.
Their father had gone to bed early in Wuhan. Qiao had arranged another examination of his wrist, which still troubled him when he repaired small electrical appliances for neighbours. Jianming objected to the expense. Qiao told him he could object after the appointment was completed.
Yanchuan called him the next morning.
“You don’t have to pretend the pain has gone,” he said.
“And you don’t have to make your sister report on my hand,” Jianming replied.
“I asked how you were.”
“You asked her first.”
He was right. Yanchuan apologized and listened while his father described the actual problem. The pain was mild most days, sharper when he tightened a fitting at an awkward angle. They agreed on nothing except that the appointment would happen.
At work Chen reviewed the new pilot schedule. One proposed milestone measured reduction in rejected recommendations. Yanchuan crossed it out and substituted a measure of whether reasons for rejection had been understood, acted upon, or correctly left unresolved.
“We could show improvement,” Chen said.
“We can show whether our guesses are becoming more useful. Fewer refusals on their own could mean people have stopped bothering to answer.”
Chen considered it, then approved the revision for discussion with the client.
A week later Qiao sent another photograph of the blank night-list form. A new category had been added: care arrangement pending, with space for a named follow-up. It was a small change, introduced by the ward manager after several nurses raised the same issue.
“Did the software fix it?” Yanchuan asked.
“No,” she answered. “We fixed the form. The software can catch up.”
He kept the photograph beside the pilot’s next revision plan. The new box was barely wide enough for Qiao’s handwriting. She filled it in on her next shift and asked the ward clerk to make the space larger.
