“It should be usable with no training.”
We hear that a lot.
But is it valid?
Sometimes.
Perhaps even often.
But not always.
!"
Let’s look at some exceptions.
International Space Station
OK, so that one has very few users.
Flight simulator (partial) for pilot task training
Weather forecasting
Those have a few more.
Next time you fly, think about this —
Air traffic control
More than 47,000 airports worldwide.
How many controllers?
Three differences Complex domains
Workers have a lot to understand
Complex tasks Users have a lot to learn about what to do and how
High risk Cost of errors is very high, even death

C
da Vinci remote surgical system Addenbrooke Treatment Centre
Would you want your operation done by a
surgeon who hadn’t been trained on the system?
I didn’t think so.
What’s the real point?
It should be usable with no
unnecessary training.
Caution:
This does not mean…
…address UX problems with training…
