Rhetoric is communication designed to have a persuasive effect on its audience.
Here are some common rhetorical reasons for making diagrams and maps:
2. Flow Diagram
A flow diagram outlines the steps in a process, including conditions a user or system is under, and connections between tasks.
Conditions are rules that dictate the flow. For example, the path I take in the flow is different if I’m ordering for pickup or delivery.
There are spaces between the places we make.
When you’re cleaning up a big mess, assess the spaces between places as well as the places themselves.
A place is a space designated for a specific purpose.
For example, if you built a public park, you might make a path to walk on, a picnic area, a playground, some bathrooms, and a soccer field. These areas were made with tasks in mind.
If parkgoers wear down a path through your fresh laid grass, you as the parkitect (ha!) could see it as an annoyance. Or you could see it as a space between places and pave over it so people can get where they want to go without walking through the mud.
A space is an open, free, or unoccupied area.
Space may not have a designated purpose yet, but that doesn’t stop users from going there.
No matter what you’re making, your users will find spaces between places. They bring their own context and channels with them, and they show you where you should go next. Find areas in flux and shine a light on them.
Taxonomies can be sequential.
Sequence is the order in which something is experienced. Some sequences happen in a logical order, where the steps are outlined ahead of time.
Other sequences are more complex with alternative paths and variations based on the circumstances, preferences, or choices of the user or the system.
These are all examples of sequences:
- A software installation wizard
- New patient sign-up forms
- A refund process at a retail store
- A job application
- A recipe
- A fiction book
- The checkout process on a website
Like any taxonomy, the categories and labels you choose affect how clear a sequence is to use.
