When I was named Chief Financial Officer with an “Interim” tag in front of the title, it was both a great challenge and a great opportunity. I had prepared for years with the goal of becoming a CFO, but when I looked at the criteria in the written description for the CFO position, I understood why our CEO and chairman, Mark Rohr, chose to make me interim rather than full CFO. I came to Celanese with a broad variety of experiences and skill sets in finance and, since 2010, I had had direct ownership of most of the finance and shared services functions at Celanese. But while I had accumulated a great deal of finance experience—and that is what put me in the running for the job—it was clear that I was missing other types of experience. The external search criteria called for candidates who had deep engagement with the business and experience leading cross-company initiatives. My experience in these areas was limited because I’d spent my career playing mostly in the finance sandbox.
