Welcome to the brave new world of cost accountants, or cost and management accountants (CMAs) as they are called today. In this twenty-first century version, they do not aspire to end their careers as CFOs. They desire to become CEOs, or corporate leaders. They are not just obsessed with costs, accounting, taxes, and audits. They are passionate about growth and investments, topline and bottom-line, strategies rather than tactics, integrated thinking driven by AI-linked data analytics and, more importantly, predictive decision-making process. We got the idea to showcase leading CMAs through discussions with C-Suite Executives, and other experts. They are CFOs, and CEOs.
