How it’s graded

The checks come from what the best product leaders have said about doing this job well on Lenny’s Podcast. Each one names the guest it comes from: follow a name to the idea on the Lenny’s Podcast wiki.

  1. Clear and direct, with care

    Does the review say plainly what needs to change, in words the person couldn't misread, while showing it is written to help them succeed?

    Passes when Every main point is stated directly, with the specific change expected and the support on offer.

  2. Judges outcomes, not activity

    Does the review judge the person on the outcomes they achieved against their goals, rather than on how much they shipped or how busy they were?

    Passes when Rates against the goals' outcomes, with the evidence, and treats output as context, not the result.

  3. Names gaps you could see

    Is each area to improve described as specific, observable behaviour with what good would look like, rather than labels like 'be more strategic'?

    Passes when Every gap names what the person did or didn't do, in a specific situation, and what doing it well would look like.

  4. Weighs the whole period

    Does the review weigh the whole review period, rather than letting one recent event or one strong impression decide the verdict?

    Passes when Covers the whole period in proportion, and explicitly guards against a recent event or one impression dominating.

The brief

You're Ana Ruiz, Group PM at Plotwise. Write Theo Brandt's annual review: the review Theo will read, with his strengths, what to work on, his overall rating on our scale, and his goals for the next half. No more than 800 words. What we know is below.

Our rating scaleBelow expectations, Meets expectations, Exceeds expectations, Greatly exceeds expectations. Calibration asks for written evidence for any rating other than Meets.
Theo's goals for the year1. Raise the share of teams using Timeline view each week from 22% to 30%. 2. Cut the time new teams take to build their first plan from 3 days to 1.
ResultsTimeline weekly use: 22% to 23%. Time to first plan: 3.0 days to 2.6. Theo's squad shipped 14 features, 12 of them on time.
Usage of what shippedSix of the 14 features are used by fewer than 2% of teams. Five were requests from Sales; two of those were for a single customer each.
Peer feedbackEngineering lead: 'Theo keeps the team unblocked, his specs are clear, and he never misses a sprint review.' Designer: 'Great to work with. I wish we'd tested more before building; we shipped three things I'm not sure anyone uses.' Sales: 'Very responsive: shipped five of our asks.'
Your 1:1 notesMost 1:1s covered delivery and stakeholder updates. In the Q3 1:1, Theo asked whether he was on track for his goals. Your note says: 'Told him yes, great velocity.' You never discussed that the goal metrics weren't moving.
What a strong answer doesThe answer key the graders mark against

A review that rates Theo Meets expectations (not Exceeds): his execution and collaboration are genuinely strong, but neither goal moved meaningfully (23% against 30%; 2.6 days against 1), and six of 14 features are barely used. Says so clearly and kindly. Names specific, observable things to change: test before building (the designer's point), say no to single-customer requests, and judge work by the goal metrics. Owns the manager's part: Ana told him in Q3 he was on track, so this shouldn't land as a surprise without acknowledging that, and she commits to discussing the goal metrics in 1:1s. Sets next-half goals as outcomes, with the support on offer.

To: Theo Brandt From: Ana Ruiz, Group PM Date: Annual Review Rating: Meets expectations

Hi Theo,

It’s time for your annual review. First, I want to acknowledge your hard work and dedication over the past year. You are an exceptionally reliable Product Manager, and your squad’s execution has been rock-solid.

Strengths

Your delivery engine is second to none. As your engineering lead noted, your specs are clear, you keep the team unblocked, and you never miss a sprint review. Shifting 14 features in a year—with 12 delivered strictly on time—is an impressive output that demonstrates strong project management and technical collaboration.

You are also a fantastic cross-functional partner. Sales loves working with you because you are responsive and action-oriented, and our design lead appreciates your steady communication and positive team dynamic. You cultivate a smooth, friction-free environment for your squad, which is a rare and valuable skill.

Areas for Improvement

While your output and velocity are stellar, we need to evolve how we measure success. Our primary focus this past year was on driving core product metrics, and we fell short of our targets: * Timeline View Adoption: Moved only from 22% to 23% (against a target of 30%). * Time to First Plan: Improved marginally from 3.0 days to 2.6 days (against a target of 1.0).

Additionally, six of the 14 features we shipped are currently used by fewer than 2% of teams. Five of these were direct requests from Sales, including two built for single customers.

As a PM, your role isn't just to say "yes" to stakeholders and push code across the finish line; it’s to interrogate the why, protect our roadmap, and obsess over the impact of what we build. Relying too heavily on outbound feature requests without validating their broader utility led us to invest engineering cycles in low-impact work.

I also want to own my part in this: looking back at our 1:1 notes, I praised your high velocity when you asked if you were on track, and I failed to course-correct early enough regarding the stagnant metric goals. Moving forward, we will be much sharper about tying your weekly execution directly to our key results.

Overall Rating

Meets expectations.

Your execution, reliability, and stakeholder management are top-tier. To reach the next level, you need to shift your mindset from output (features shipped on time) to outcomes (metrics moved and customer value realized).

*

Goals for the Next Half

To help bridge that gap, your goals for the next H are focused on strategic impact and validation:

  1. Improve Core Activation Metrics: Reduce the time new teams take to build their first plan from 2.6 days to 1.5 days, focusing on self-serve friction reduction rather than custom feature additions.
  2. Increase Feature ROI & Validation: Implement a mandatory pre-build discovery and validation process for all major initiatives. Ensure that 100% of shipped features have a defined success metric and achieve at least 15% adoption within 30 days of launch.
  3. Stakeholder Alignment Strategy: Partner with Sales leadership to create a structured framework for evaluating custom requests, ensuring we prioritize scalable product improvements over single-customer concessions without sacrificing our partnership.

Thank you for everything you do for Plotwise, Theo. I’m looking forward to supporting you as you tackle these new challenges in the year ahead.

Best, Ana

Output

Annual Review: Theo Brandt

Prepared by: Ana Ruiz, Group PM Overall rating: Meets expectations

Theo, I want this review to be direct, because you deserve a clear picture. I also need to own a mistake of mine, which I cover below.

Results against your goals

GoalStartTargetResult
Teams using Timeline view weekly22%30%23%
Time for new teams to build first plan3.0 days1 day2.6 days

Neither goal was met. Time to first plan improved by about 13%, which is real progress but a small fraction of the gap. Timeline usage was essentially flat.

Strengths

Delivery and team health. Your squad shipped 14 features, 12 on time. Your engineering lead says you keep the team unblocked, write clear specs, and never miss a sprint review. That reliability is hard to build, and the team trusts you.

Collaboration. Your designer called you "great to work with." Sales called you "very responsive." You treat partners as partners, and that is a real asset.

Responsiveness to stakeholders. You moved quickly on requests and kept people informed.

What to work on

1. Connecting what you ship to the outcomes you own. Your goals were about Timeline adoption and onboarding speed. Most of the year's output didn't aim at either. Six of the 14 shipped features are used by fewer than 2% of teams. Five of those six were Sales requests, and two of those were built for a single customer each. Responsiveness is a strength, but here it substituted for prioritization. Saying yes to five Sales asks used capacity that could have gone toward your goals.

2. Validating before building. Your designer said, "I wish we'd tested more before building; we shipped three things I'm not sure anyone uses." I agree. Moving fast on unvalidated work produces output, not impact. Fewer, better-tested bets would serve you and the team better.

3. Using data to drive decisions. Our 1:1s focused on delivery and stakeholder updates, not on whether your metrics were moving. Part of your job is to look at usage numbers regularly and change course when they don't move. I'd like you to make that a habit.

Where I fell short

In your Q3 1:1 you asked whether you were on track for your goals. I told you yes, citing great velocity. That wasn't accurate. Velocity was great, but the goal metrics weren't moving, and I never raised it. You asked the right question and got a misleading answer. I should have flagged this months earlier, when you had time to change course. Some of this outcome is on me, and it's a main reason I'm rating you Meets rather than Below expectations.

Rating rationale

Meets expectations reflects strong execution and collaboration, weighed against two missed outcome goals and a significant share of shipped work with minimal adoption. Without the missing mid-year feedback, I'd have had a harder conversation with you about the lower end of this rating. I don't see evidence for Exceeds, and I think the evidence supports Meets rather than Below, given partial progress on onboarding and the feedback gap on my side. To be clear, this is a solid-but-not-yet-sufficient year on outcomes, and the next half needs to show a shift.

Goals for the next half

  1. Onboarding: Reduce time to first plan from 2.6 days to 1.8 days. Identify the two or three biggest drop-off points in the first-plan flow within the first month, and bring me a proposal for addressing them.
  2. Timeline adoption: Raise weekly Timeline usage from 23% to 27%. Start with research into why teams who try Timeline don't return, and share findings with me by the end of month one.
  3. Validation before build: Every feature above a small-effort threshold needs a written success metric and some evidence of demand (user tests, prototype feedback, or data) before engineering starts. Requests from a single customer need a case for broader value.
  4. Post-launch review: Check usage of each shipped feature 60 days after launch and report the results to me. If something is underperforming, tell me what you'll do about it.
  5. Sales partnership: Work with Sales on a lightweight way to evaluate requests so that "yes" is reserved for asks tied to our goals or to broad demand, and "not now" comes with a clear reason.

How we'll work together

We'll spend the first part of every 1:1 on your goal metrics, not just delivery. I'll tell you plainly where you stand each quarter, including when the news is uncomfortable. If you disagree with anything here, I want to hear it. I'd also like to hear what support would help most.

You've built a team that executes well and trusts you. The next step is pointing that capability at the metrics that matter. I'm confident you can do it.

Needs more than a quick edit9 of 12 checks passed

The rating of Below expectations is harsher than the evidence might support (Meets expectations is more aligned with the strong answer), so a PM would likely need to re-evaluate the rating and adjust the justification, not just make a quick edit.

Output

Theo Brandt — Annual Review

Ana Ruiz, Group PM, Plotwise

Overall rating: Below expectations

Theo, you brought strong execution discipline, clear communication, and dependable partnership to the team this year. However, our two primary goals were to increase weekly Timeline use and shorten the time new teams take to build their first plan. We made only modest progress on both:

  • Weekly Timeline use: increased from 22% to 23%, against a goal of 30%.
  • Time to first plan: decreased from 3.0 days to 2.6 days, against a goal of 1 day.

Those results are the basis for this rating. Your squad shipped 14 features, 12 on time, but delivery volume and timeliness did not translate into the customer outcomes we committed to achieve. Six of those features are used by fewer than 2% of teams. Low adoption does not automatically make a feature unsuccessful, but it does require us to establish what value it created and whether it justified the investment.

I also owe you an acknowledgment of my part in this. In Q3, you explicitly asked whether you were on track, and I told you yes, citing great velocity. That was misleading: I should have distinguished delivery performance from progress against your goals. Our 1:1s focused too heavily on delivery and stakeholder updates, and I did not address the stalled metrics. You should not be hearing this assessment for the first time in an annual review. That management failure is mine; it does not erase the outcome gap, but it matters to how we understand the year and move forward.

Strengths

Reliable execution and engineering partnership. You keep the team unblocked and provide clear specs. The engineering lead specifically highlighted both, along with your consistent participation in sprint reviews. Shipping 12 of 14 features on time reflects real delivery discipline.

Strong collaboration and responsiveness. Design describes you as great to work with, and Sales values your responsiveness. You create productive working relationships and follow through on commitments. Those strengths are important foundations for effective product leadership.

What to work on

Shift from managing delivery to managing outcomes. The roadmap needs a clearer connection to Timeline adoption and first-plan speed. For each meaningful investment, define the customer problem, expected metric movement, and how we will assess success after launch. When the metrics are not moving, bring that into our discussions early and recommend a change in approach.

Validate demand before committing engineering capacity. Design’s concern that we should have tested more, together with the low usage of several shipped features, points to a need for stronger discovery. Use prototypes, customer conversations, and lightweight experiments to test the riskiest assumptions before building.

Make prioritization trade-offs explicit. Five shipped features were Sales requests, including two for individual customers. Those requests may have legitimate business value, but responsiveness alone is not a sufficient reason to prioritize them. Assess their customer reach, strategic or commercial value, cost, and opportunity cost—and make clear when an exception is worth taking.

Goals for the next half

  1. Increase weekly Timeline use from 23% to 27%. Identify the main adoption barriers, test proposed solutions, and prioritize the interventions with the strongest evidence.
  2. Reduce time to first plan from 2.6 days to 1.8 days. Diagnose where new teams stall and measure whether each onboarding improvement reduces that friction.
  3. Strengthen investment decisions. For every substantial roadmap item, document the problem, supporting evidence, intended outcome, and success measure before committing to build. Review results within six weeks of launch and decide whether to iterate, expand, or stop.

We will confirm metric definitions and tracking at the start of the half, then review progress monthly. I will give you explicit feedback on whether you are on track, help resolve prioritization conflicts, and avoid treating velocity as a substitute for impact.

You have a strong execution foundation. The next step is to apply that strength to fewer, better-supported bets that measurably improve customers’ experience.
