The Pipeline is Full and Still the Water’s Not Flowing Freely

The latest McKinsey Women in the Workplace report contains a finding that should stop every senior leader in their tracks.

Women now represent 48% of entry-level leaders. By the time you reach the C-suite, that figure is 29%.

The pipeline is full. The talent is there. Something is happening on the way up.

For years, the default explanation has been ambition. Women, at a certain point, simply want different things. They opt out. They prioritise family. They make a choice.

McKinsey’s 2025 data dismantles that story precisely.

Where career support exists, and specifically where sponsorship exists, men and women have identical ambitions. Remove that support, and the desire to reach the top fades. Not because the ambition was never there. Because the calculation changed.

The women I work with at senior level are not lacking ambition. They are doing maths.

They can see what the next level requires. The time. The exposure. The performance of a version of leadership that doesn’t fit who they are or how they think. They have watched colleagues navigate that terrain and emerge diminished rather than fulfilled. They have done everything right — the experience, the results, the relationships — and been passed over anyway, often without explanation.

At a certain point, the rational response is not to push harder. It is to stop.

That is not a pipeline problem. It is a systems problem.

What this means if you’re a senior woman.

The loss of ambition you may be feeling is not yours. It belongs to the system that produced it. The McKinsey data makes this explicit: deprive any leader, male or female, of sponsorship and structural support, and their desire to advance diminishes. You are not the variable. The support is the variable.

What looks like a personal decision is the entirely predictable output of an environment that stopped investing in your progression, possibly long before you noticed.

What this means if you lead an organisation.

Here is the part of the McKinsey data that tends to get less attention.

The system that carried you to the top: the sponsorship, the stretch assignments, the informal networks, the assumption that you were leadership material, was not neutral. It was selectively applied. And the leaders who benefited most from it are, in many cases, now the ones running the organisations where it continues to operate exactly as before.

This is not an accusation. It is a structural observation.

Most senior male leaders I work with did not design this system. They navigated it skilfully, as it was presented to them, and they reached the top because they were good at what it rewarded. That is a legitimate achievement.

But the same system that fostered their success is now quietly compromising the organisations they lead.

Because the world those organisations are operating in has changed fundamentally. Accelerating technology. Increasing uncertainty. Complexity that no single perspective, however experienced, can navigate alone. The organisations best equipped to meet that world are the ones that can draw on the full range of their talent. Diverse thinking. Different vantage points. The kind of cognitive range that only comes when the people at the top don’t all share the same formation.

And that is precisely what the pipeline problem is forfeiting.

The women leaving at senior level are not a diversity statistic. They are some of your most experienced, most resilient, most battle-tested leaders. People who have navigated a system not designed for them for decades and kept performing anyway. When they stop, the organisation doesn’t just lose a headcount. It loses a perspective that is genuinely irreplaceable.

McKinsey notes their own data may present a rosier picture than reality because the companies willing to participate in diversity research are disproportionately the ones already doing the work. The actual figures are likely worse than reported.

The uncomfortable truth is this: the system is working perfectly. It is producing exactly the leadership pipeline it was designed to produce, one that looks increasingly unlike the complexity it needs to navigate.

The pipeline is full.

The question is this: What is your organisation doing to the water?
