In this, the fourth and final installment of our discussions with RJon Robins on the seven essential parts of a law firm, we move to the 5th and 6th essential parts of a law firm: physical plant and financial metrics and controls. The topic of physical plant naturally brings up the question of “whither physical law firms in the time of COVID?” We also discuss how intellectual property may be the most significant way that you can add value to your law firm. We wrap with a discussion of financial metrics and controls and the one metric that you as a law firm should be tracking. We also take a detour and talk briefly about Joe Walsh.
