Performance support is actually not meant to be lifelong learning; it is simply just-in-time information accessed at a point of time, situation, and location.
We forget almost 80% of what we learn in just 30 days – unless we get an opportunity to apply that knowledge.This is precisely why you need performance support. These short content nuggets (typically how performance support is packaged) help learners to learn a specific task and solve an immediate problem or perform on a given task. They could remind learners how to apply their formal training on the job or just be standalone pieces focusing on an entirely new knowledge/skill.
