The missing half hour
The organisers of a youth project day had prepared a timetable in which every session fitted neatly into its box. The first workshop ended at eleven, and the next began at eleven. On paper, there was no wasted time. In the building, however, people and equipment could not move from one activity to another instantly.
Nina noticed the problem while checking responsibilities. At eleven, one team would still be answering questions in the workshop room, while another would be waiting outside with materials. The information desk would also need a new volunteer at exactly the moment when the previous volunteer was due to begin a presentation upstairs. Several different tasks overlapped in ways the original timetable did not show.
The organisers drew a second version with separate lines for rooms, equipment and people. They added time for leaving a room, checking that it was ready and welcoming the next group. They also included a short handover at the information desk. During that period, both volunteers would be present, so unfinished questions would not disappear between shifts.
The revised plan contained fewer sessions, which initially disappointed some organisers. They worried that visitors would see the empty spaces as a lack of activity. Nina suggested describing those spaces honestly as breaks and movement time. A busy programme was not useful if participants spent it rushing or waiting outside unavailable rooms.
The plan still could not prevent every delay. A clear update point was therefore included, and volunteers were asked to check the current version rather than an old screenshot. By planning what would be happening at the same time, the group made hidden conflicts visible. The timetable became a tool for coordination rather than a picture of an unrealistically perfect day.
