Why cascaded training loses its value, and what to do instead

Train the trainer looks efficient on a spreadsheet. It rarely survives the second retelling.

The logic is sound: teach the senior layer well, have them teach the next, and the capability spreads at a fraction of the cost. The problem is that the thing being passed on isn’t information. It is a practised behaviour, and behaviour doesn’t copy cleanly.

At each layer, the retelling loses the parts that were hardest to hold: the live feedback, the awkward rehearsal, the specific situations that made it real. What arrives at the front line is a summary of a summary, delivered by someone who is not a coach and has their own job to do.

Design for the layer you actually care about

If the behaviour you need is on the front line, build the work for the front line, in their situations, and use the senior layer to set the expectation rather than to teach. Where scale is genuinely needed, add capacity rather than dilution: more coaches delivering the same design, with the same reinforcement and the same measurement.

That is why forefront is a team rather than one person. Every session runs to one standard, so a multi-cohort rollout lands the same way whoever is in the room.
