Organization Design, Business Model Generation
Org Designer is a newer job title.

Molly West Duffy is a designer for Ideo. She designs organizations. “My job is to use the tools of design to enhance organizational culture, boost collaboration and teamwork, improve structures and processes, enable learning and development, and create a sense of purpose and belonging.” When she meets someone she says: “I help people and teams do their best work.” 

Being a designer committed to clear communication, she recognizes that while this elevator pitch is suitably short, it's still kinda vague. So, to be more specific, she documented a day in the life. There’s good learning in here.
