"The traditional methods of advancing women are not moving the needle, and under-representation of women around the world has become an economic and social travesty," Mercer's Pat Milligan said quoting the 'Global Leader of When Women Thrive' report.
She said while leaders have been focusing on women at the top, they are largely ignoring the female talent pipelines that are critical to maintaining progress.
"Focus on women across the complete talent pipeline and in all organisational and people processes needs to become a way of life. A key driver of this change will be how both men and women champion the cause of women at work," Mercer's Shanthi Naresh said.
In terms of regional rankings, Latin America is projected to increase women representation to 49 per cent in 2025 from 36 per cent in 2015, followed by Australia and New Zealand moving to 40 per cent from 35 per cent.
The report said Asia is projected to have the lowest representation of women in 2025.
A focus on increasing representation at the top of organisations will not help Asia move out of last place over the next decade in terms of overall female representation.
Organisations here are least likely, compared with other regions, to be focused on many of the drivers of gender diversity parameters like the engagement of their middle managers (30 per cent) and their male employees (28 per cent), the adoption of a rigorous pay equity process (25 per cent), or the review of performance ratings by gender to look for adverse impact (20 per cent).
It also revealed that only 9 per cent of organisations surveyed globally offer women-focused retirement and savings programmes with the US and Canada ranking first (14 per cent).
Globally, women make up 33 per cent of managers, 26 per cent of senior managers and only 20 per cent of executives.
