# Worked examples


> Four fleets, the labels they use, and what each one makes easy.
## A single office, twelve screens

Two dimensions are enough.

```text
reception   canteen   meeting-room   corridor
finance     hr        operations
```

A screen carries one of each: the space it is in, and the team that owns its content.

**What it makes easy.** HR updates its own screens without touching anyone else's. A building-wide notice targets nothing at all and goes on **All Screens**. Adding a meeting room is one label.

## Twenty sites, four screens each

Site is the dominant dimension, so it goes first.

```text
frankfurt   manchester   lyon   ...
reception   warehouse    canteen
24h
```

**What it makes easy.** A country-wide campaign targets nothing site-specific and reaches all eighty. A single site's screens are one label. Screens that never switch off are `24h`, so a schedule for overnight content targets them without listing them.

**What to resist.** `frankfurt-reception`. Frankfurt plus reception already expresses it.

## A manufacturing plant

Here the useful dimension is not geography, it is who is looking.

```text
plant-floor   control-room   canteen   entrance
safety        production     hr
portrait
```

**What it makes easy.** A safety notice reaches `plant-floor` immediately without anybody deciding which screens those are. Orientation is a label because content is authored differently for it, and a portrait playlist targeting `portrait` never lands on a landscape wall.

## An agency running screens for clients

Clients belong in separate [workspaces](/docs/workspaces/), not separate labels. Isolation is the point, and labels do not provide it.

Inside each client's workspace, label by that client's own geography and space types. A [shared playlist](/docs/playlists/managing/share-with-another-workspace/) is how the agency's own content reaches all of them.

## The pattern underneath all four

Between two and four dimensions. Every screen carries one label from each. No combinations. No campaigns.
