PwC Found Immersive Practice Makes People 4x Faster. Most Companies Still Train Like It's 2015.
Learning design hasn't caught up with what's now possible.
For decades, the constraint was real: practising a hard conversation — a pricing pushback, a tough performance review, a board member's pointed question — meant finding a human role-play partner, booking a room, and hoping the scenario felt realistic enough to matter. That constraint shaped almost everything about how corporate training got built. Compress the practice into a single workshop day, because practice was expensive and human time was scarce.
That constraint doesn't hold anymore.
What the evidence says
PwC's study of 1,600 employees found that immersive, simulation-based practice helped people apply new skills up to 4x faster and left them 275% more confident acting on what they'd learned, compared with classroom training alone. A separate meta-analysis spanning 65 studies of adult workforce learners found that computer-based simulation training measurably outperformed passive instruction on procedural knowledge, retention, and self-efficacy. And in live customer-support settings, generative AI guidance during the job itself has been shown to lift issue resolution by roughly 15% per hour on average — with the largest gains going to the newest, least experienced employees.
The pattern across all of it is the same: practice, repeated and realistic, changes what people actually do — not just what they know. AI hasn't invented that principle. It's made it affordable and scalable for the first time.
Which raises an uncomfortable question for anyone setting a learning budget this year. If realistic, repeatable practice is now cheap enough to run continuously instead of once, why are most leadership and sales programs still designed around a single day in a room?
Spend went up. Outcomes didn't move.
Most training still ends the moment the workshop does. The room empties, feedback forms come back around 4.6 out of 5, and three months later nobody can point to what actually changed. Gartner's 2025 research captured this gap precisely: although 75% of organisations significantly updated their leadership programs and more than half increased spend, they are "not seeing results" — only 36% of HR leaders believe their current programs genuinely prepare leaders for what's next.
That gap is a design choice, not an inevitability. And it's a choice that made more sense before continuous practice was technically or economically feasible than it does now.
The organisations getting ahead of this aren't necessarily spending more. They're restructuring when and how often practice happens — building learning as something that runs continuously alongside real work, rather than something that happens once and hopes for the best.
That shift is worth sitting with regardless of which vendor, platform, or internal team ends up building it. The harder question isn't whether AI-enabled practice works; the evidence on that is accumulating quickly. It's whether your organisation's learning design has caught up to what's now possible, or whether it's still optimised for a constraint that no longer exists.
What's the last leadership or sales program at your organisation you could point to and honestly say: "that changed what people do, not just what they know"?
