In my opinion, confidence and training are the two most important aspects of an associate’s development. The open assignment system naturally furthers both. It gives associates early opportunities to take ownership over work and early practical opportunities. The result is confidence gained. You will then carry that confidence into your other cases, and it usually manifests in being more decisive and comfortable.
The open assignment system also gives you the agency to find people you connect with and who have actual incentive to mentor and develop you as a lawyer.
As an associate, you have the agency to take on (or not take on) certain cases. Baked into the system is an incentive to teach and develop new associates. My philosophy for navigating the open assignment system is to prioritize working with the lawyers who have taken an interest in my development. That’s naturally resulted in mentorship, which is what I think associates crave most. The open assignment system is a forum for you to go out and build those relationships; it’s embedded in the culture of the Firm.
