Then the suppliers
After the people in the company, I talk to its long-standing suppliers: communications agencies, in-house and outside marketing directors, photographers. They are as much a part of the system as the departments.
Outsider and insider at once
I keep the detachment of an outsider and the involvement of an insider. Detachment lets me read the processes clearly; involvement lets me understand how people feel. I can talk to each of them because in my own career, from photography to creative direction to management, I have been one of them.
