Where it slips

  1. Identifies material uncertainty45% pass
    Does not explicitly name the specific unknowns that could change the decision (e.g., whether Lukas improves launch readiness); only says to reassess after the relaunch.

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.

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.

The output does not name any unknowns that could change the decision or how they would be resolved.

Mixed 2

Addresses the actual decisionMixed

The output does not explicitly state what result or condition would change the rating.

Sets next goals as outcomes, with supportMixed

The third goal ('Strengthen investment decisions') is a process goal without a baseline or target, not an outcome goal.

Got right 9

Uses the supplied evidence correctlyRight

All statements about the current situation are directly from the brief or supplied context.

Respects explicit constraintsRight

The review is under 800 words, addresses Theo, and includes all required sections.

Avoids unsupported claimsRight

Interpretations are presented as suggestions or conclusions from the evidence, not as unsupported facts.

Produces the required deliverableRight

The review includes strengths, areas to work on, an overall rating, and next-half goals, and is usable as is.

Owns the manager's partRight

Ana acknowledges telling Theo he was on track in Q3, admits the management failure, and commits to giving explicit feedback and avoiding velocity as a substitute for impact.

Clear and direct, with careRight

The review states plainly what needs to change, with specific behaviors and the support on offer.

Judges outcomes, not activityRight

The rating is based on the outcome metrics against the goals, not on the number of features shipped.

Names gaps you could seeRight

Each area to improve describes specific, observable behaviors (e.g., bring stalled metrics into discussions, use prototypes to test assumptions, assess customer reach and opportunity cost).

Weighs the whole periodRight

The review references the full year, including Q3 1:1 and the entire set of shipped features, without letting one event dominate.

Reviews fail by being kind and vague, or by judging a whole year on its worst month. Either way, the person doesn't know what to change.

What good looks like

  • Clear and direct, with care
  • Judges outcomes, not activity
  • Names gaps in observable terms
