Twenty years is a long time to watch the same problem from different angles. I have worked with international teams in manufacturing, financial services, professional services, technology, pharmaceuticals, and consumer goods. Large multinationals and ambitious mid-sized companies. Teams expanding into Europe, into Latin America, into Asia. Teams that were genuinely committed to making international work work.
And across all of that — the industries, the geographies, the company sizes, the individual profiles — the failure mode has been almost identical. Not always. But often enough that I stopped being surprised by it a long time ago.
Here is what I have learned. And yes — it is not what most people expect.
This is the thing that took me a few years to see clearly, because it runs against the most intuitive explanation. When international teams underperform, the first question is usually: do they have enough English? And the answer is almost always: yes, actually. They do.
The teams I have watched struggle the most in international environments are frequently not struggling with language. They are struggling with something harder to name and harder to fix: they do not know how to perform in those environments. They know how to communicate. That is not the same thing.
A team can conduct a fluent meeting in English and leave every person in that meeting with a different understanding of what was decided.
A team can deliver a competent presentation to an international committee and generate no movement whatsoever. A team can execute a cross-border project with full technical capability and watch it fragment at the implementation stage, for reasons that nobody can clearly articulate. I have seen all of these, repeatedly, in teams with strong English and genuine commitment.
The problem is not language. The problem is that we have been training teams for communication and assuming that performance would follow. It does not.

When I started in this work, the dominant model for preparing international teams was language training. Companies invested in English courses, in communication skills, in business English workshops. The assumption was logical: if the barrier is linguistic, remove the linguistic barrier and performance will improve.
That assumption was right for a generation of teams where language was genuinely the main constraint. For many companies in the 1990s and early 2000s, getting teams to a functional level of English was the critical development priority, and it produced real results.
But something changed. As English proficiency became more widespread — as it became a baseline expectation rather than a differentiator — the teams that continued to underperform in international environments were no longer the ones with weak English. They were the ones who had solved the language problem and discovered that there was another problem underneath it, one they had never been trained for.
That problem is professional performance in cross-cultural, high-stakes, ambiguous international contexts. And for that problem, most organisations still reach for the tool they know: more language training, or a cultural awareness workshop, or a general communication skills programme. None of which addresses what actually needs to be developed.
After twenty years, when I sit with a leadership team that is concerned about their international performance, I am not listening for the language problem. I am listening for five things.
I am listening for whether their people can structure arguments in ways that produce the same interpretation across different cultural frameworks — not just communicate content, but sequence and frame it so that the right conclusions are drawn on the other side.
I am listening for whether their people can intervene with confidence in high-stakes international settings — not just participate, but shape the conversation, hold positions under pressure, redirect when needed.
I am listening for whether their people can influence international counterparts — not just present to them, but move them, build coalitions across markets, make arguments that land in contexts where persuasion follows different rules.
I am listening for whether their people have genuine cultural intelligence — not knowledge of cultural frameworks, but the dynamic ability to read a specific situation as it unfolds and adapt in real time.
And I am listening for whether their people can manage complexity without losing direction — because international environments are inherently ambiguous, and the teams that perform consistently are the ones whose people can operate with clarity when everything around them is uncertain.
When I find gaps in these five areas — and I almost always do — the conversation about development becomes much more specific. Not “how do we improve their English” but “how do we build their capacity to perform in the situations where we are currently losing ground.”
If I could go back and tell myself something at the start of this work, it would be this: the problem was never the language. The problem was always the performance. Language is the entry condition. Performance is what the organisation actually needs.
The companies that understood this early — that invested in developing the professional capabilities that international performance requires, not just the linguistic ones — built teams that performed consistently across markets, in ways that their competitors with equally fluent but less capable teams simply could not match.
That understanding is what International Performance Training® is built on. Not as a theory, but as the practical conclusion of twenty years of watching what works and what does not. The framework changes as we learn more. The core insight has not changed at all.
