As companies grow increasingly global and complex, the siloed treasury function is becoming a relic of eras past. Managing cash flow, handling foreign exchange, and maximizing earnings on excess liquidity remain core treasury functions, of course. But in this day and age, successful treasurers are those who extend themselves beyond the role's traditional duties.

This trend is exemplified by the winners of the 18th annual Alexander Hamilton Awards in the category Cash Management & Liquidity Optimization, sponsored by Kyriba and Strategic Treasurer. The winning projects are diverse, but all five involved a project lead within treasury who reached across functional or even corporate lines to bring about significant change.

Through these projects, this year's winners demonstrated important lessons about managing a treasury function in the modern age. Key among those lessons: Communicate broadly, communicate clearly, and communicate often.
