So it’s been about 30 days since I started working here at Cummins and so far it has been a wonderful experience. Today I’m writing from Des Moines, Iowa visiting Cummins Central Power , one of Cummins Distributors. I feel fully immersed in my job, and although I’m still a newbie, I am contributing. The book The First 90 Days although very good, almost seems written for a high executive and not for a newly minted MBA Graduate, but there are a few things that have shaped my experience in the past 30 days.
