Action Analysis
Action analysis is an evaluation procedure that is used to estimate the
time needed to perform a task (by executing the correct series of actions
using the interface).
There are two variations:
- Formal action analysis
looks at every atomic action in detail, and estimates the
time to perform it. Thinking, deciding, and looking should not be forgotten,
because they take quite a bit of time as well..
- Back-of-the-envelope action analysis
is a quick and dirty approach, estimating the time for larger (compound)
actions to be "a few seconds".
