However, even if your new organization doesn’t have formal transition support, you should engage with HR and your new boss about creating a 90-day transition plan. If you have been promoted, find out whether there are competency models describing the requirements of your new role (but don’t assume they tell the whole story). If you have been hired from the outside, ask for help in identifying and connecting with key stakeholders or finding a cultural interpreter. These people often are natural historians who can give you insight into how the organization has evolved and changed.
