"The First 90 Days" was a book that I was planning to read for a long while but I especially postponed it till I become a "manager". Just after learning that I got that title, I directly downloaded the e-book and read it. It includes many tactics for the first 90 days during your onboarding. Here are my highlights from the book:
The president of the United States gets 100 days to prove himself; you get 90. The actions you take during your first few months in a new role will largely determine whether you succeed or fail.
Transitions into new roles are the most challenging
times in the professional lives of leaders.
