The Five Barriers, Named Directly
From the untracked leak to DEI commitments that live in values statements, not accountability.
Old Playbook vs. Next Practice
What most representation initiatives get wrong, and what actually changes the outcome.
A Four-Step Starting Diagnostic
Concrete questions to ask this quarter, starting with a single chart most organizations have never built.
The Chart Nobody Had Drawn
An organization proud of its diversity numbers once ran a simple exercise: plot the representation of women at every level, from entry to the executive committee, on a single chart. The line at entry level looked healthy. By the time it reached senior leadership, it had thinned to almost nothing. Nobody in the room had seen that shape before, because nobody had ever asked the data to be presented that way.
The organization wasn’t short on talented women. It had a pipeline that leaked, quietly and consistently, at a specific point nobody had been measuring.
The Scale of the Leak, in Numbers
The pattern in that story isn’t unusual, it’s close to the norm. McKinsey’s Women in the Workplace research, now in its 11th consecutive year and drawing on roughly 10,000 employees across more than 120 organizations, found that women hold just 29% of C-suite roles, unchanged from the year before, despite representing about 49% of entry-level employees. The gap doesn’t open all at once. It compounds, level by level, across the entire pipeline.
The size of that drop-off is measurable at each transition point too. Research cited by workplace analysts found that global representation falls by roughly 18% moving from senior individual-contributor roles into first-line management, and by around 30% moving from VP-level roles into the C-suite. Both numbers matter, but the first one deserves more attention than it usually gets.

Take the Assessment →The Broken Rung Is the First Rung, Not the Last
It’s tempting to assume the biggest leadership gap sits near the top, boardrooms and C-suites are the most visible, so they draw the most scrutiny. But the data consistently points earlier: the single largest barrier tends to appear at the first promotion into management, well before anyone is being considered for an executive role.
This matters enormously for where organizations focus their energy. A mentorship program aimed at existing senior women, or a board-diversity target set five years out, does very little to fix a leak that’s already happened two or three levels below. Fewer women promoted into that first management tier means fewer women available for every promotion that follows it. The fix has to start where the leak starts, not where it becomes most visible.
Why Sponsorship Closes a Gap Mentorship Can't
One of the more counterintuitive findings in recent research: when women receive the same level of career support that men typically do, sponsorship, advocacy, visible backing, in rooms they aren’t in, the commonly cited “ambition gap” between men and women largely disappears. The gap was never really about ambition. It was about access to the kind of advocacy that turns readiness into an actual promotion.
This is precisely the distinction between mentorship and sponsorship that matters most. Mentorship helps someone grow. Sponsorship is a senior leader spending their own credibility to advocate for a specific person, by name, when that person isn’t in the room. Most organizations have real mentorship infrastructure and almost no structured sponsorship, and then are genuinely puzzled when development activity doesn’t convert into advancement.
Progress Is Real, But It's Also Fragile
It’s worth being direct about something uncomfortable: recent research suggests this progress is not guaranteed to hold. Grant Thornton’s Women in Business research found that women’s share of senior leadership roles among the companies it tracks fell from 35% two years ago to 31% today, a decline, not a plateau, at exactly the moment investors and future talent are paying closer attention to leadership composition.
Some of this appears tied to organizations quietly scaling back the specific programs that most directly support women’s advancement. Recent research found that a meaningful share of employers reduced or discontinued flexible work arrangements and remote or hybrid options over the past year, and a notable share of employers openly admitted to placing little or no priority on women’s career advancement at all. None of this happens through an announced policy reversal. It happens the same way the leak itself happens: quietly, unmeasured, until someone finally draws the chart.
Closing this gap isn’t primarily a training-budget question. It’s a question of whether the judgment being built, when to trust AI output, when to verify it, when to keep a task fully human, is being taught deliberately, or assumed to happen on its own.

The full guide walks through each of these in depth. In brief:
- The untracked leak — representation narrows with seniority, and almost nobody plots it explicitly by level.
- Mentorship mistaken for sponsorship — real development programs exist alongside almost no structured advocacy.
- Policy that exists on paper and carries a quiet penalty in practice — benefits nobody uses without a visible cost aren’t really benefits.
- Bias hidden inside evaluation language, not policy — how “ambition” and “readiness” get read in the room, not what’s written down.
- DEI commitments that live in values statements, not leader accountability — commitments that aren’t tied to how leaders are themselves measured tend to survive as language and fail as practice.

Explore Women in Leadership Programs →Why the Standard Fix Falls Short
The standard fix tends to add a program on top of an unchanged system, a leadership development cohort, a mentorship circle, launched with real intention and tracked against a single company-wide representation number. The next-practice version does something different: it changes what the system itself measures and rewards, tracking representation by level and transition point, building sponsorship as a distinct tracked practice, and making advancement outcomes part of how senior leaders are themselves evaluated.

Frequently Asked Questions
Where does the biggest drop in women’s leadership representation actually happen?
Research consistently points to the first promotion into management, not the move into the C-suite, as the single largest leak point. Fewer women promoted at that first transition means fewer women available for every leadership level that follows.
What’s the difference between mentorship and sponsorship?
Mentorship helps someone grow through advice and guidance. Sponsorship is a senior leader actively using their own credibility to advocate for a specific person, by name, in rooms she isn’t in. Most organizations have real mentorship infrastructure and almost no structured sponsorship.
Does closing the leadership gender gap actually require special ambition-building programs for women?
Research suggests the commonly cited ambition gap largely disappears when women receive the same level of career support and sponsorship that men typically get. The gap tends to be about access to advocacy, not a difference in ambition itself.
Is progress on women’s leadership representation guaranteed to continue?
Recent research suggests otherwise. Some tracked measures of women’s senior leadership representation have declined in the past two years, coinciding with organizations scaling back flexible work arrangements and career-advancement programs.
How can an organization tell if its pipeline is leaking, beyond looking at overall representation numbers?
Plot representation explicitly by level, from entry to executive committee, rather than relying on a single aggregate figure. The specific point where the line thins most sharply usually reveals a leak that an aggregate number hides entirely.
