Your first 90 days in a new job: a simple plan

Starting a new job is exciting and a little uncertain. You want to make a good impression, but you do not yet know the people, the tools or the unwritten rules. The first three months matter more than most people realise: they shape how your manager and colleagues see you for a long time.

A simple plan helps you use this time well.

Month one: listen and learn

Your main job in the first month is to understand how things work.

• Learn the business. Who are the customers? What does the company sell? How does your team's work connect to that?
• Learn the people. Have short conversations with everyone you will work with. Ask what they do, what makes their work hard and how you can help.
• Learn the tools and processes. Take notes on everything. Write down steps so you do not have to ask the same question twice.
• Clarify expectations. Ask your manager directly: "What would a great first three months look like for me?"

It is fine not to know things. Ask questions, but try to find the answer yourself first, and group small questions together rather than interrupting all day.

Month two: start contributing

By the second month, aim to take ownership of a few tasks from start to finish.

• Deliver small wins. Finish tasks on time and do them well. Reliability builds trust faster than anything else.
• Share progress. Do not wait for your manager to ask. A short update at the end of each week shows that you are organised.
• Notice problems, gently. You will see things that could be done better. Note them down, but be careful about criticising processes before you understand why they exist.

Month three: build on what you learned

By the third month, you should know the basics well. Now you can start adding more value.

• Suggest one improvement. Pick something small and practical from your notes. Explain the problem, your idea and how it would help.
• Take on a bit more. Ask for a slightly bigger task or responsibility.
• Ask for feedback. "What should I keep doing, and what should I do differently?" Listen without defending yourself, and thank them.

Build good relationships

Your relationships at work affect your happiness and your growth. A few simple habits help:

• Be friendly and polite with everyone, not just senior people
• Keep your promises, even small ones like "I will send that by lunch"
• Give credit to others when work goes well
• Admit mistakes quickly and explain how you will fix them

Understand how your manager works

Every manager is different. Some like detailed updates, others prefer a short message. Some want you to ask questions any time, others prefer a daily check-in. Observe, or simply ask: "How do you prefer to get updates?" Working the way your manager works makes both of your lives easier.

Look after yourself

New jobs are tiring. You are taking in a lot of information and meeting many people. Keep a regular sleep routine, take your breaks, and do not try to prove yourself by working late every day. Steady, good work over months matters far more than heroic effort in week one.

A 90-day review with yourself

At the end of three months, look back:

1. What have I learned?
2. What have I delivered?
3. What feedback have I received?
4. What do I want to achieve in the next three months?

Share a short version with your manager. It shows that you are thoughtful about your growth, and it sets up a useful conversation about your next steps.
