Just in Time (JiT) education & training is ” … the negotiated provision, in corporate (or community) workplaces, of learner-generated immediate skill formation.”*
It’s a little like automobile manufacture. Car plants don’t have warehourses full of wheels and windscreens and widgets. These things are delivered ‘just in time’ for manufacture by a range of suppliers. The focus is on getting the car made as cost-effectively as possible, and that means only using the component elements as the need arises, rather than ‘stocking up’ against the day when the need *might* arise. It’s an action orientation: both the “know how” and the “know why” are up for constant renegotiation as actions unfold.
