A Gartner Inc. survey of 140 in-house legal departments found that the most cost-effective legal departments devoted almost twice as much of their budgets to training as their higher-cost peers.

The most cost-effective legal departments spent 2.04% of their in-house budget on training and development compared to higher-cost departments that spent only 1.04% on training. The researchers concluded that investing in training helped increase productivity while not increasing head count and led to a decrease in spending on expert or outside support.
