Write Out Your Plan and Priorities
Write out your plan and priorities. Once you have assessed the business situation, your strengths and the relationship you want with your boss and the team, write out your priorities and goals. Identify in the plan where you can achieve early wins. Addressing problems that your boss cares about will go a long way toward building credibility and cementing your access to resources. Pick solutions that will yield visible results. You may initiate a pilot project to establish an early win.
Ask these questions: What are your top ten priorities in the first 90 days? Which ones can you tackle and solve quickly? Which priorities are important to your boss? Which people and groups will influence [help or hinder] you in achieving your priorities?
