What aspect of memory is this idea based on?

My idea is based on the working memory model, short-term memory and long-term memory. We are given a task to complete which would pass into our working memory and can sometimes not pass into the long-term memory. This means that the task is not remembered or very minute details are remembered. This can lead to decreased productivity, loss of money and stress. Situations where the task would not be passed into the long-term memory are when multiple tasks are presented, the tasks are presented at a stressful time, the person needed to remember the task is tired or ill and concentration is not instated so that the task is not even passed into the short term memory.
