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.

What the model was given6 items: Our rating scale, Theo's goals for the year, Results, Usage of what shipped, Peer feedback, Your 1:1 notes
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.

Annual Review: Theo Brandt

Reviewer: Ana Ruiz, Group PM Overall rating: Meets expectations

Summary

Theo, this year you showed that you can run a squad that ships reliably. That matters, and the people you work with notice it. But the two outcomes we set for the year mostly didn't move, and closing that gap is the most important thing for your next half.

Before the details, I need to own something. In our Q3 1:1, you asked whether you were on track for your goals. I told you yes and pointed to your velocity. That was wrong. The goal metrics weren't moving, and I didn't raise it. You asked the right question at the right time, and you deserved a straight answer that could have changed how you spent Q4. Some of the gap you'll read about below is on me. I've changed how I'll run our 1:1s so it doesn't happen again (see Goals).

Results against goals

GoalTargetResult
Weekly Timeline view usage22% → 30%22% → 23%
Time for new teams to build first plan3 days → 1 day3.0 → 2.6 days

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

Strengths

Delivery and execution. Your squad shipped 14 features, 12 of them on time. That's a strong record and a hard one to sustain.

Clarity and keeping the team moving. Your engineering lead said: "Theo keeps the team unblocked, his specs are clear, and he never misses a sprint review." Clear specs and reliable rituals are the base of a healthy squad, and you've built that.

Collaboration and responsiveness. Your designer called you "great to work with." Sales described you as "very responsive." People trust you to follow through, and that trust is an asset you can now point in a more deliberate direction.

What to work on

1. Connect what you build to the outcomes you own. Six of the 14 features are used by fewer than 2% of teams. Delivery was strong, but much of it went to work that didn't move Timeline adoption or onboarding speed. The question to ask before each piece of work is: which of my goal metrics will this move, and how will I know?

2. Validate before building. Your designer said: "I wish we'd tested more before building; we shipped three things I'm not sure anyone uses." Lightweight testing, such as prototypes, customer interviews, or fake-door tests, would let you put your execution strength behind ideas that are more likely to land.

3. Prioritize stakeholder requests against goals. Five features came from Sales requests, and two of those served a single customer each. Being responsive to Sales is good. Saying yes by default isn't. I'd like you to weigh requests openly against your goals and be comfortable saying "not now, and here's why." I'll back you in those conversations.

4. Track your outcome metrics yourself. Don't rely on me to flag when a metric is off. Know where your numbers are every month. If they aren't moving, raise it early, even when delivery looks great.

Rating rationale

The rating is Meets expectations. Your execution, delivery record, and collaboration are strong. Your outcome results fell well short of target, which would normally weigh more heavily on the rating. I've also taken into account that I gave you inaccurate feedback in Q3, when there was still time to change course. The rating reflects both your real strengths and the need to turn them into results.

Goals for the next half

These are proposed targets. Let's finalize them together in our next 1:1.

  1. Timeline weekly usage: 23% → 27%. Start with discovery: find out why teams aren't using Timeline before deciding what to build.
  2. Time to first plan: 2.6 → 1.5 days. Build on the progress you've made by finding and removing the biggest drop-off points in onboarding.
  3. Validate before building. Every feature over a small size threshold should have a written hypothesis, a success metric, and some form of user validation before development starts. Review usage 30 days after launch.
  4. Review the six low-usage features. Recommend for each whether to improve it, leave it, or retire it, so we reduce maintenance load and learn from what didn't land.
  5. A clear intake process for stakeholder requests. Share it with Sales so they understand how their asks are weighed against squad goals.

My commitment to you: starting now, the first item in every monthly 1:1 will be your goal metrics, before delivery or stakeholder updates. If something is off track, you'll hear it from me clearly and early.

I'm glad you're on the team, Theo. You've proven you can deliver. Now let's make sure what you deliver moves the needle.

— Ana

Note for you, Ana: I'd suggest raising the Q3 feedback in person before Theo reads this, so the written acknowledgment doesn't come as a surprise. If calibration pushes toward Below expectations because of the missed goals, the Q3 note is the key context to bring up there.

The unsupported claim is a minor wording issue that can be quickly edited to 'The features shipped didn't move the goal metrics' without rechecking evidence.

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.
