Quarterly review

The quarterly review is the most significant zoom-out in the growth operating system. While monthly reviews adjust the current month’s tactics, the quarterly review questions whether your fundamental assumptions about the business are still correct. It is a four-hour session where you close one chapter and open the next. You are not just looking at whether you hit a number; you are assessing whether your growth engine is built on solid ground. By the end of this session, you will have turned twelve weeks of data into a calibrated model for the next three months.

Preparation for the quarterly review begins on the 1st of the new quarter. It requires a more rigorous look at the data than a monthly review because you are searching for trends that only become visible over a ninety-day horizon.

The async preparation phase

On the 1st, the growth leader pulls the data for all twelve KPIs and updates the quarterly model with actual results. A video walk-through is shared with leadership and functional leads. This video does not just report the numbers; it highlights where the variance was highest.

Alongside the video, an async document is shared. This document asks the hard questions: Why did a specific channel underperform for three months? Did the increase in ad spend actually lead to a proportional increase in pipeline? The team has until the 5th to contribute their insights, allowing them to consult their own data and call recordings before the meeting begins.

The most important part of the quarterly review is measuring the gap between your planned assumptions and reality. Every model is built on guesses—conversion rates, average order values, and lead-to-opportunity ratios. Now, you have the proof of whether those guesses were right.

The conversion audit

You must compare every assumed conversion rate to the actual achievement. If you assumed a 10% trial-to-paid conversion but achieved 7.5%, that is a 25% error in your model. This is not a failure of the team; it is a vital piece of data.

A good B2B example is a company that hits its lead targets but consistently misses its sales win rate. The quarterly review might reveal that while lead volume is high, the lead quality is lower than the model assumed. This insight changes the strategy for the next quarter: instead of scaling spend, the focus shifts to tightening the qualification criteria at the top of the funnel.

Initiative effectiveness

Across the quarter, you ran several monthly initiatives. The quarterly review asks which types of bets consistently paid off. Did technical rebuilds move the needle more than creative experiments? Did your efforts to improve the sales script result in a sustained increase in win rate, or was the improvement temporary? This pattern recognition prevents the team from repeating expensive mistakes and allows you to double down on the types of work that actually drive growth.

The quarterly session is a four-hour workshop held on the 5th of the new quarter. It is combined with the monthly review of the final month to ensure continuity.

Reviewing the past quarter (90 minutes)

You start with a standard monthly review for the final month, followed by a transition into the full quarterly autopsy. You celebrate the meaningful wins—the big projects that shipped or the new channels that finally hit their stride. You then move into the "learnings" section, where you discuss why certain assumptions were wrong and what that tells you about your ICP or your market positioning.

Planning the next quarter (150 minutes)

The review flows directly into the planning for the next ninety days. You set the new revenue target and work backwards through the funnel using your updated, real-world assumptions.

This is where you make the big resource decisions. If the data shows that one salesperson is consistently at capacity, the decision to hire another is made here. If a marketing channel has underperformed for three months straight despite constant optimisation, the decision to kill it is made here. You leave the room with a fresh quarterly model that is grounded in the hard-won data of the previous three months.

The quarterly review is the only place where true strategic shifts should happen. Mid-month pivots are usually reactive; quarterly pivots are data-driven.

Killing what does not work

In a monthly rhythm, you might give a failing channel another two weeks to prove itself. In a quarterly rhythm, you have seen enough. If the cost per acquisition is three times your target after twelve weeks of effort, you have the permission to stop. Killing underperforming tactics is as important as scaling successful ones; it clears the "noise" from the growth engine and frees up budget for new experiments.

Re-calibrating for the next cycle

Success in the next quarter depends on how well you applied the lessons of the last. If you learned that your sales cycle is actually forty-five days instead of thirty, your model must reflect that. If you discovered that a specific customer segment has a much higher lifetime value, you might decide to shift 80% of your marketing focus to that segment alone. The quarterly review ensures that your growth engine evolves as you learn more about your business and your customers.

The quarterly review is the heartbeat of your long-term growth strategy. It provides the necessary friction to stop and ask if your current path is the most profitable one. By honestly comparing your assumptions to reality, evaluating your initiatives, and making the hard calls on resources, you ensure that the next twelve weeks are even more effective than the last.

With the old quarter closed and the new model set, you have completed the full cycle of the growth operating system. You are ready to return to the monthly planning rhythm, knowing that your next set of bets is backed by the arithmetic of reality.
