Craig Silliman, executive vice president for public policy and general counsel at Verizon, Feb 2016

We have a lot of people in-house who are deeply embedded with the business, people who have a good general sense of the business, an ability to issue spot, an ability to support the business on what I’ll call a horizontal basis. By definition, when we’re bringing in outside counsel, we’re bringing them in as a vertical staff, as a highly specialized resource on one particular issue.

The best outside counsel understand they are the client of the in-house legal team, and should make that team look good.
