30-60-90 Day Plan for a New Job -- What to Do in Your First 3 Months

Why the First 90 Days Define Your Next 3 Years

Research consistently shows that how well new employees integrate in their first 90 days predicts their tenure and trajectory. Leaders who struggle with onboarding are 3x more likely to leave within 18 months. Those who build strong networks and deliver early wins in the first quarter are significantly more likely to be high performers 2 years later.

The first 90 days aren't just about surviving -- they're your highest-leverage time to shape how people see you.

Days 1-30: Listen, Learn, and Map

The single rule for Month 1: Don't try to change anything yet. Even if you can see problems clearly.

What to do:

Learn the landscape:

• •Understand the org chart -- formal and informal. Who has influence that isn't reflected in titles?
• •Read the last 6 months of all-hands decks, strategy docs, and product reviews you can access
• •Review your team's recent postmortems, retrospectives, and planning docs
• •Understand what "success" looks like for your team and for the company this year

Build relationships intentionally:

• •Schedule 1:1s with every direct teammate in the first 2 weeks
• •Request 30-minute calls with key stakeholders in adjacent teams
• •Ask the same 5 questions in every 1:1: What's going well? What's broken? What should I prioritize? What do people expect from this role? What would you do differently if you were starting fresh?
• •Write down everything. Your fresh perspective is an asset -- it fades within 3 months.

Establish your working style:

• •Discuss communication preferences with your manager (async-first? Daily syncs? Slack or email?)
• •Understand how decisions get made on the team
• •Learn the review and approval processes

Key deliverable by end of Month 1:

A written "understanding document" shared with your manager: "Here's what I've learned, here's how I think about the priorities, and here's where I think I can contribute most. Does this match your view?"

Days 31-60: Contribute and Build Trust

Month 2 goal: Deliver one visible, meaningful piece of work that demonstrates your capabilities.

What to do:

Pick one "early win" project:

Choose something that is:

• •Achievable in 2-4 weeks
• •Visible to your manager and stakeholders
• •Meaningful (not trivial, not so huge it can't be finished)
• •Within your existing skill set (not a stretch project -- Month 1 is not the time)

Ship it cleanly. Be communicative about progress. Write a brief summary of what you did and the outcome.

Deepen key relationships:

• •Schedule follow-up conversations with the most important stakeholders from Month 1
• •Identify 2-3 people who will be your strongest internal advocates -- invest in those relationships
• •Find a potential mentor or senior peer who is willing to give you candid feedback

Establish routines:

• •Regular 1:1 cadence with manager (weekly or bi-weekly)
• •Sprint/planning cycle participation if applicable
• •Team rituals you should be part of

Key deliverable by end of Month 2:

Completed early win with written summary. One or two advocates who have seen your work.

Days 61-90: Optimize and Align on the Long Term

Month 3 goal: Align on your 6-12 month goals and begin building toward them.

What to do:

Have the performance conversation:

By Day 90, you should have asked your manager explicitly:

• •"What does success look like for me in the first 6 months? The first year?"
• •"What are the 2-3 most important things I can contribute to this year?"
• •"Is there anything I should be doing differently that I might not be aware of yet?"

Propose improvements (now it's time):

You've been here long enough to understand context. Now you can bring the fresh perspective: "I noticed [X pattern]. In my experience, [Y approach] might address this. What do you think?" This is the right timing -- you're no longer a newcomer who doesn't understand the context.

Plan your 6-month arc:

What do you want to accomplish in months 4-6? What relationships do you need to deepen? What skills do you want to develop? Articulate this to your manager -- it shows initiative and makes them a partner in your growth.

The Common Pitfalls in the First 90 Days

Frequently Asked Questions

Should I bring a written 30-60-90 day plan to the first day?

Yes, for management and senior roles -- it signals seriousness and preparation. For IC roles, it's optional but welcomed. Share it with your manager in Week 1, not as a rigid commitment but as a starting point for alignment.

What if I realize the job is very different from what was described?

Have a direct conversation with your manager at Day 30. Most gaps between expectation and reality can be navigated if caught early. If not addressable, you've learned this early enough to make a clear-eyed decision.
