Learning can happen over a short period of time or over longer periods of time. When learning happens over a short period of time, the user tries out different strategies to complete tasks. A short period of time might be several minutes, hours, or days. For example, if users have to submit their timesheets every day using a time-keeping application, they try to quickly develop some type of mental model of how the application works. Memory is not a big factor in learnability; it is more about adapting strategies to maximize efficiency. Within a few hours or days, it is hoped that maximum efficiency is achieved.
