Usability testing is widely used in the commercial world during the process of developing new products, especially software and websites. However, it appears to be rarely used in the development of e-learning in medical education. ⋯ Testing under the conditions that the e-learning intervention will typically be used is the preferred method but more extreme situations can provide useful information. Product development should be iterative and rapid cycles of testing and refinement are essential to produce an effective e-learning intervention.
