Why sales education will never be the same again

At Kestio, half of what we do is sales education: a catalogue of more than 120 programmes, twenty years in the field, thousands of sales reps supported. It is precisely because we train that we can ask the question head-on: does classic sales education still deliver a return on investment?

The honest answer is uncomfortable. Not because sales education would be useless, it remains essential to onboard people, pass on fundamentals, set a framework. But because, as it is most often practised (one-off, top-down, with no follow-up), it runs into a mechanical obstacle that neither the trainer's quality nor the participants' motivation is enough to remove: forgetting.

The real problem is not motivation, it is memory

In the late 19^th century, psychologist Hermann Ebbinghaus measured how fast we forget what we have just learned. His “forgetting curve” shows a steep drop over the first few days, then a low plateau. Applied to classic top-down training, it produces a figure that should alarm any training manager.

70% forgotten in seven days

Seven days after a training session, with no reactivation, only 30 % of the content remains on average. The person can give you back less than a third of it. Try it: review the takeaways the day after a session and you will see the scale of the loss. It is not a matter of commitment or motivation, it is how the brain works.

The one-shot session: 80% forgotten within three months

The most common format — two days in a room, once — amplifies the effect. After three months, roughly 80 % is lost. How to open a meeting, question, reformulate, argue, handle an objection: practice barely changes if that single session is the only thing on offer. Many training providers do not show these figures, because they are uncomfortable. We prefer to face them, because they dictate what has to come next.

What really sets a top performer apart

Ask a team the question: what sets the best sales rep apart from the rest? Talent? Effort? Their network? The number of reps? All four sound true, but if you have to pick one, the answer almost always converges on the same factor: repetition. The best ones have simply made more first contacts, run more discovery calls, handled more objections.

That observation raises an uncomfortable question. If skill comes from repetition, and the only time a sales rep repeats is in a real client meeting, then you are using your prospect pipeline as a training ground. You train during the match. No athlete, no musician works that way.

Why do we expect from a sales rep what we expect from no athlete?

Compare practice volumes across activities that, like sales, rely on the repeated gesture and on adapting to context.

Skill does not come from information. It comes from practice.

An athlete trains hundreds of times before competing. A musician rehearses before the concert. The sales rep, meanwhile, is expected to peak in front of the client with two days of training a year. And improvise the rest. Knowing how to do something gets confused with having seen it once.

Improvisation isn't the enemy of method, it's the outcome of it. A jazz musician improvises because they have enough command of their technique. In a sales meeting, you adapt constantly to personalities and context, but you adapt all the better when you have a set of tools worked on beforehand, rather than live in front of the client.

We measure sales education in the wrong place

The Kirkpatrick model describes four levels for evaluating a training programme: satisfaction (did they like it?), learning (did they learn?), behaviour (did practice change in the field?) and results (did performance improve?).

In practice, most programmes stop at the first level: a satisfaction survey, “happy / not happy”. Behaviour change is rarely measured, and hardly ever a single euro of ROI. Not every training course can be assessed on results: a two-year sales cycle rules out calling back in two years to check. But you can, and you should, look at what the training actually shifted in behaviour and on intermediate indicators.

The sales skills that are gaining value

The job has changed deeply. Faced with better-informed buyers and with online or self-service alternatives, the bar has risen. The skills that make the difference are no longer the technical fundamentals of the 1980s — they are relational, strategic, cognitive. And those are precisely the ones you cannot acquire in one day a year.

You can pile up slides, e-learning modules and seminars: until the sales gesture is repeated regularly, nothing changes for good. That is where it all turns.

From education to training: the continuous loop

Yesterday, the path was linear: framing, training, assessment, debrief… and then? Usually nothing. The programme stops right where practice should start. The shift is to replace that dead-end path with a continuous loop, short and regular.

What made this loop impossible until now was time. A busy manager cannot coach every sales rep every week. AI removes that barrier: it takes over the training and the first debrief, while the manager focuses on higher-value coaching. Fifteen to twenty minutes of training a week, combined with regular manager attention, is enough to shift the performance level; especially for the 60 to 70% of the team whose level is “inconsistent”, and who represent the real room for progress.

The manager does not replace AI; AI does not replace the manager. Combined, they multiply each other. That conviction is the foundation of BizCoach AI: turning twenty years of field expertise into continuous sales training, across an entire team.
