Explain an event change before people make the trip

Keep a community event’s update, travel and arrival experience consistent when plans change.

UX, product and service designers, researchers and experience teams.

Your approach: Use a written storyboard, journey map, message examples, rough sketch or prose. Visual polish and specialist design software are unnecessary.

The problem

Design how a free neighborhood craft event communicates a move indoors after rain. Cover the experience of deciding whether to travel, finding the current plan and arriving at either location. Choose a few useful touchpoints and show their wording; you do not need to design an app.

  • The event is at 2 p.m.; organizers decide at 10 a.m. whether to move from the park to a hall 800 metres away.
  • 180 people expressed interest, 50 used a printed flyer and some will not see a same-day message.
  • Two volunteers can update notices and help at the park. The hall holds 100 people at once and has a step-free entrance on a side street.

Work within these constraints

One current plan

Give organizers and visitors a consistent source of the current time, location and entry instructions; explain how old notices are handled.

Missed message

Provide a useful path for someone who only has the printed flyer and arrives at the park.

Arrival information

Explain the step-free route and what happens if the hall is full, without promising a reserved place to everyone.

Volunteer limit

Declare how many volunteers your communication and park-help plan requires.

Required target: ≤ 2 volunteers

What to deliver

1

Change and arrival journey

Map or narrate organizer actions and visitor decisions before departure and at each location.

2

Message examples

Write a move notice, a notice left at the park and a full-hall message with a clear next step.

3

Two missed connections

Trace a visitor who misses the update and a visitor looking for step-free access while the hall is full.

4

Check and improve

Explain how volunteers verify consistent notices and how you would test whether visitors understand them.
