Fit A good fit between the HCI elements of the human, the computer, and the
task that needs to be performed leads to performance and well-being, as shown in
Figure 14.1. Just as it is important that new shoes comfortably fit the shape of your
foot, hold up during the activity you will be doing (such as running), and are made
of a material (such as leather) that is durable and cost-effective, so too is it important
that the fit among the user, computer, and task all correspond.
Analysts want the best fit in their design. You want to make the best possible
use of people in designing a computerized task that is intended to meet an organizational
objective. Better fit is meant to result in better performance and greater
overall well-being for the human involved in the system.
