Even with its status as the No. 1 company on the 2021 Washington Technology Top 100, Leidos is focused on what's changing in the market and the priorities and needs of its customers. 

On the cusp of his retirement, Chief Financial Officer James Reagan talks with Editor Nick Wakeman about what a change culture means at Leidos and why that is a critical element of growth strategy. That outlook drives its decisions around acquisitions, divestitures and where it invests its research-and-development dollars.

The result has been a track record of organic growth in the double digits.
