The end of President Biden’s first 100 days approaches, and, as with past U.S. presidents, he will be judged by his goals and accomplishments during that time period. A new GC/CCO can also aim to get key initiatives, such as setting the tone for legal and compliance going forward, off the ground within the first 100 days on the job. This first article in a three-part series offers advice for starting the GC/CCO role on the right foot, including how to prepare before day one and the best way to approach the first 100 days. The second installment will explore how new GC/CCOs can accomplish two crucial goals in the first 100 days – gathering knowledge about the firm and building the foundation for solid relationships with key people. The third article will discuss how new GC/CCOs can balance their day-to-day work with settling into the organization, as well as how to advocate for improvements.
