Reducing the memory burden to prevent slips and mistakes involves minimizing the amount of information users must remember while completing tasks. This approach is especially helpful in environments where distractions or multitasking are common.

Even if users are interrupted, they can quickly and accurately resume their tasks, making the interaction with the system more efficient and error-free. For instance, imagine users booking a multi-city flight. A well-designed booking system will keep a visible summary of all chosen destinations, dates, and flights as users add each leg of their journey. This prevents users from having to remember each selection or from booking duplicate flights for the same date.

By continuously displaying this information, the system helps users verify their choices at each step without relying solely on memory.
