Training Doesn't Work
There. I said it.
Not because people can't learn. Not because your trainers aren't talented. Not because the content is wrong. Not because people are bad.
Training doesn't work because of how we're wired and because most organizations aren't compensating for how people learn.
The numbers are brutal.
Studies consistently show that only about 15% of training is ever applied on the job without additional support. Only 10% of companies have a formal strategy to ensure training content is applied in the field. You read that right: nine out of ten organizations spend money on training with no plan to make it stick.
And it gets worse when you look at improvement programs specifically. According to a Wall Street Journal study, nearly 60% of all corporate Six Sigma initiatives fail to consistently meet their objectives. A review of academic literature identified 34 common failure factors across 56 papers on Lean, Six Sigma, and LSS spanning nearly two decades. The same themes showed up every time: lack of top management commitment, resistance to culture change, poor communication, and inadequate training reinforcement.
If you read my other articles, I argue that accountability failure is at the core of how factories fail... and nobody is working in that space.
But training a process and subsequently following it is the whole idea of a process. If you can't even train it, you can't possibly be following it.
These training numbers prove indisputably that accountability issues are rampant in the industrial world.
The Forgetting Curve
German psychologist Hermann Ebbinghaus mapped the Forgetting Curve, and if you haven't designed your training system to compensate for this research, you don't have a training program. You have a compliance activity.
Without reinforcement: 40% of new information is forgotten within 20 minutes. 55% within an hour. 70% within 24 hours. 80% within a month.
Your operators sit through a four-hour training on lockout/tagout, standard work, or contamination control procedures. They pass the quiz. They get the signature on the form. And within a week, most of it is gone. Not because they don't care but because that's how human memory works.
The brain is not a hard drive. It is an adaptive filter. It keeps what it uses. It discards the rest.
Ebbinghaus concluded that the best methods for strengthening memory are repetition based on active recall, especially spaced repetition, where each review session extends the interval before the next is needed. He published a mathematical formula for it in 1885. We've had the answer for 140 years.
If you're designing a training program, spaced repetition is worth a deep dive.
The bottom line:
Training is an event. Learning is a system. If your organization is running training events without a system designed to overcome Ebbinghaus' Forgetting Curve, then it's not working.
The Forgetting Curve doesn't care about your training budget. Build around it or keep wondering why nothing sticks.
Oh, and if your training system doesn't work... your accountability system definitely doesn't work. And can't.
