Good article,
As previously mentioned in a comment by Karen, meeting with key stakeholders is critical.  I also believe that meeting those on the "front line" is equally as important.  Understanding the vibe on the manufacturing floor or in the trenches of any department offers a fantastic opportunity to just understand the culture, but to build trust at that base level.  Nothing creates as positive a "buzz" as when employees feel truly listened to from the higher-ups.
