My youngest daughter starts school in September (her big sister is already in the same school). As part of the settling in period the new starters, and parents, were invited to have lunch at school.
I heard one of my fellow parents say that going into the dining room at lunchtime is one of the most daunting parts of starting school for 4 and 5 year olds. And that makes sense: the hall is a big space, there's a system and routine to learn and there's potential for a lot of other older children there.
Thinking about this from a work perspective the school has effectively engaged in CX (customer experience) / UX (user experience) and message testing.
