WCOOC: The Next Decade
Anchoring WCOOC’s purpose & direction for the future
2026 marks the tenth anniversary of Women in the COO Community. In 2016, Armstrong Wolfe’s CEO, Maurice Evlyn-Bufton, wrote an article titled ‘The Case for Equity-Plus Representation for Women in the COO Community.’
Maurice had spent 15 years in executive search, focusing principally on business management roles – the Chief Operating Officer, the Chief Administration Officer, Chief of Staff, and Chief Control Officer. After interviewing and referencing hundreds, if not thousands, of COOs, he concluded that women make better COOs – the question was: why?
In his paper, Maurice interviewed 50 female managing director COOs and most of their managers to investigate his belief. The conclusions were summarized in his paper, which, when presented to the then Group COO at Standard Chartered Bank, Doris Honold, prompted the comment: “WCOOC – we should do something with this.” Maurice asked, “WCOOC, what is that?” to which Doris replied, “Women in the COO Community.”
Three months later, Doris hosted the first event, and from this, Armstrong Wolfe’s inclusivity initiative was born.

“I would like to take this opportunity to thank all those who have supported WCOOC on its ten-year journey. Specifically, I would like to thank Emma Prophet, the outgoing 2025 WCOOC Chair, who has done wonders in taking WCOOC into its anniversary year. I also want to welcome the 2026 Chair, Penny Tunbridge.
Appropriately, Penny was a panellist alongside Doris at WCOOC’s inaugural event in 2016 and has been a mainstay and advocate for its work throughout its journey. I very much look forward to working with the three regional and global steering groups in the year ahead as we celebrate ten years of playing our part in seeking equality of opportunity for women in financial services, while promoting the COO role as a career destination for tomorrow’s rising leadership.”

“I am excited to be a part of the WCOOC Steering Group as the work of the WCOOC is important to continue to connect and advance the women in the global COO Community.”
