"Why does our plan keep surviving the offsite and dying in Q2?" Because the plan was never wired into how money and decisions actually move. A growth operating model is that wiring: the thesis, funding rule, decision rights and cadence that turn a strategy deck into funded work. McKinsey puts the cost of weak wiring at roughly 30 percent of a strategy's potential, lost quietly, every year.
What a growth operating model must include
A growth operating model needs five working parts: a written growth thesis, a funding mechanism, decision rights, an operating cadence, and a measurement spine. Miss one and the rest leak. A thesis without a funding mechanism is a wish, and a cadence without decision rights is a status meeting with better slides.
The parts are not equally hard. Most companies already own a thesis and a calendar. What they lack is the connective tissue: who can move money, how much, how fast, and against what evidence. McKinsey's operating-model explainer reports that top-performing companies capture only about 70 percent of their strategy's full potential, with operating model shortcomings taking the remainder. A 30 percent haircut on a plan everyone signed is not a motivation problem. It is a wiring problem.
Read the table below as a minimum specification. If you cannot name the owner of each row, you have a plan and a hope rather than a system. The decision layer sits upstream of every row in it.
| Component | What it decides | Typical owner | Failure mode |
|---|---|---|---|
| Growth thesis | Which markets and motions earn investment | CEO | A list of everything, ranked by nobody |
| Funding mechanism | How budget moves between bets mid-year | CFO | Last year's split, frozen in place |
| Decision rights | Who approves, who is consulted, who is told | COO or growth lead | Everything escalates to the exec meeting |
| Operating cadence | When evidence is reviewed and acted on | Growth lead | Review that ends in more analysis |
| Measurement spine | Which numbers count as proof | Analytics owner | Dashboards nobody disputes or uses |
How a growth operating model connects strategy to resource allocation
Connect them with a standing reallocation rule, not an annual negotiation. Decide ahead of time what share of budget is contestable each quarter, what evidence releases it, and what triggers a stop. McKinsey's report Choosing to grow: The leader's blueprint finds growth leaders are 60 percent more likely to move resources from lower-return to higher-return opportunities.
The other half of the picture is breadth. McKinsey's report Choosing to grow: The leader's blueprint report that companies addressing multiple growth pathways are 97 percent more likely to outperform their peers than companies riding a single motion. Both numbers describe the same behaviour a growth operating model is built to produce: money follows evidence quickly, and it goes to more than one place.
What a growth operating model funds first
Fund the constraint, not the loudest channel. If demand already exceeds the sales team's capacity to qualify it, buying more demand lengthens the queue instead of the revenue line. That argument is laid out in our case for treating demand as the wrong first lever.
A resource allocation framework finance will sign
Finance signs a rule, not a mood. Write three things down: the contestable share of budget, the evidence that releases the next tranche, and the kill criteria. BCG's work on resource allocation and portfolio choices keeps landing on the same conclusion, that companies moving capital between businesses on a schedule beat companies moving it during a crisis.
Which decision rights stop growth teams from stalling
Three rights set velocity: who can commit spend below a stated threshold, who can kill a test, and who can change a target. Write them with names and numbers, because Bain's decision effectiveness research finds organizations that execute decisions well are nearly 2x as likely to post top-quartile financial performance. Anything left undefined defaults to the executive meeting, which is the slowest decision venue in the company.
Bain's research on decision effectiveness ties company performance to how specific repeated decisions get made rather than to org charts, and Harvard Business Review's management archive makes the matching argument about accountability handed out without budget authority. A growth operating model earns trust when a leader can predict what happens next without attending the meeting.
Keep the consulted list short and dated. A decision with six consulted parties and no deadline gets made by whoever gets tired last. If the thresholds feel uncomfortably high, that discomfort is the point, because it is what buys back the executive calendar. Our services pages describe where this work usually starts.
Thresholds also need an expiry. A spend limit set when the company was half its current size will quietly re-centralise every decision as the business grows, and nobody notices until the pipeline review starts running long. Revisit the numbers whenever headcount or budget steps up, and write the new ones down the same day.
We saw this fail at a $42 million ARR B2B SaaS client in the first half of 2025. The written decision rights said the COO could approve spend up to $75,000 without sign-off, but for two full quarters nothing moved below six figures without a full executive review anyway, because nobody outside the leadership team had been told the threshold existed. We had written the rule down and called the job done, which was our mistake, not theirs. It took one blunt email restating the number, naming the COO directly, and setting a 90-day deadline before decisions below that threshold actually started moving at the new speed. The lesson from that account is that a decision right nobody has heard of is not a decision right, it is a sentence in a document, and a growth operating model only earns its name once the threshold reaches the people who are supposed to use it.
How to measure whether the growth operating model is working
Measure the model, not only the market. Four numbers show whether it runs: decision latency, share of budget actually reallocated, forecast error against plan, and the count of live growth pathways. McKinsey ties roughly 30 percent of unrealized strategy value to exactly this kind of operating gap, and market results lag by quarters while these four numbers move within weeks and predict the outcome.
The donut is the benchmark to argue with. If top performers leave roughly 30 percent of their strategy's value on the table, a fair goal for the first year of a growth operating model is a measurable shrink in that gap, not a perfect plan. Forrester's planning and performance research helps here because it separates planning activity from planning outcomes, which is the distinction most internal dashboards blur.
Define each number before you report it. Decision latency is the days between evidence arriving and a funding decision being recorded. Share reallocated is the percentage of the contestable pool that actually moved, which is usually smaller than anyone expects on the first pass. Forecast error is measured against the plan you funded, not the plan you quietly revised in month two.
One caution on measurement: the growth operating model should report one version of events to the board, the market and the website. When the internal story and the public story drift apart, trust goes first and budget follows. We cover that in one story told across three surfaces.
When the growth operating model should change
Change it when the thesis changes, not when a quarter disappoints. Three triggers earn a rebuild: the binding constraint moves, the economics of a funded pathway break, or the company crosses a size where the old decision rights no longer fit, the same breadth gap McKinsey ties to a 97 percent swing in above-peer growth. Everything else is tuning, and tuning belongs in the quarterly review.
A workable rhythm is a quarterly review of thresholds and pathways with an annual rebuild of the thesis and the funding rule. McKinsey's operating-model explainer is blunt about the cost of redesigning too often, because each redesign resets the learning curve for the people who have to work inside it.
The test of a growth operating model is not elegance. It is whether a leader who was absent for a month can read the last four decisions, see the rule that produced each one, and disagree with the conclusion rather than with the process.
Frequently asked questions
What is the difference between a growth strategy and the system that runs it?
A strategy names the bets. The system decides how those bets get funded, reviewed and stopped. Strategy work tends to end at the offsite, while the system is what operates on a Tuesday in March, when a channel underperforms and someone has to choose between patience and reallocation. McKinsey's operating-model explainer puts the practical cost of that gap at roughly 30 percent of a strategy's potential value for top performers. The loss does not show up as a failed plan. It shows up as a plan that was approved, partly funded, and never revisited.
How long does it take to set up a growth management system?
Expect one quarter to stand it up and two more before leaders trust it. The written parts, meaning the thesis, the spending thresholds and the meeting cadence, take weeks. The hard part is the first handful of decisions made under the new rules, because that is when people learn whether the thresholds are real. Run the first quarter with a deliberately small contestable budget so a wrong call stays cheap. Bain's work on decision effectiveness makes a similar point: organisations improve by changing how a repeated decision gets made, not by announcing a new framework.
Who should own the growth model inside the company?
One executive owns the model, usually the COO or a growth lead, with the CFO as co-signer on the funding rule and the CEO owning the thesis. Shared ownership sounds fair and produces drift, because nobody is accountable for the cadence actually happening. The owner's job is narrower than it sounds: keep the calendar, keep the evidence standard, and force a decision at each review. Harvard Business Review has argued for years that accountability without authority over resources is theatre, and that is the trap waiting here.
How much budget should stay contestable each quarter?
Pick a share small enough that a wrong call is survivable and large enough that moving it changes the quarter, then declare it before the year starts. The exact percentage matters less than the fact that it is pre-agreed, because that is what turns reallocation from a political event into a routine one. McKinsey's report Choosing to grow: The leader's blueprint finds growth leaders are 60 percent more likely to move resources from lower-return to higher-return opportunities. Teams without a standing pool usually discover that moving money mid-year costs more in meetings than the move is worth.
What is the first sign the model is broken?
Decisions start arriving late and unattributed. You see reviews that end in further analysis, budgets that match last year's split, and one pathway absorbing most of the money. Breadth is the fastest check: McKinsey reports that companies addressing multiple growth pathways are 97 percent more likely to outperform their peers, so a plan with one live pathway is already fragile. The second sign is quieter. Nobody can say who decided the last reallocation, which means the decision rights exist on paper only.
Do mid-sized B2B companies need a formal growth model?
Yes, and usually sooner than they build one. The threshold is not revenue, it is the number of people who can spend money without talking to each other. Once marketing, sales and product each hold a budget and a target, coordination by hallway stops working and the planning cycle starts producing three plans. Gartner's planning and performance management research describes the same pattern, where fragmented planning produces forecasts that leaders quietly discount. A light model, one page of thresholds plus a quarterly review, beats a heavy one nobody follows.
