Traditional cross-training is time-consuming and costly.

It requires an investment of time and attention, on the part of trainer and trainee alike, to acquire specialized knowledge that may be used only infrequently during the lawyer's career with the firm. In some law firms it involves spending hundreds or thousands of dollars to send young lawyers to external continuing legal education programs and conferences that add little, if any, relevant practical knowledge. The firm also often loses current revenue, because it cannot always charge the cross-trainee's full hourly rate for work performed outside their specialty. 

There is a better way.
