Depends on Cognitive Load Theory because even well-timed training can fail if it overwhelms the learner’s working memory.
Contrasts with front-loaded training, where people receive a large amount of information before they have a problem, context, or schema to attach it to.
Perspectives
From the learner’s perspective, just-in-time material feels more immediately useful because it answers a live question.
From the trainer’s perspective, the job is not just to teach the content, but to sequence it when learners have enough context to absorb it.
From the organization’s perspective, it can reduce wasted training by aligning learning with actual work.
