This rule converts forecasting into an early-warning mechanism for distribution investment. The company projects growth over a 12- to 18-month horizon using the capacity, cost, and expected marginal returns of existing channels. The model identifies where those channels are likely to saturate or fall short of business targets. Because a new source of predictable distribution may itself require six to eighteen months to develop, the team works backward from the projected gap and establishes an earlier trigger date. When that trigger is reached, channel development begins even if current growth still looks healthy. Actual performance is then fed back into the forecast so the saturation estimate and investment timing remain current.
Origin
Extracted from Marketing Against The Grain when Kieran Flanagan added forecasting as the way to time investment in new distribution channels.
Core principles
- 01Current growth can conceal approaching channel saturation.
- 02New distribution capabilities take months to develop.
- 03Forecasts should identify when existing channels cease supporting targets.
- 04Investment must begin before the growth gap becomes immediate.
- 05A forecast is a decision trigger, not merely a reporting artifact.
How to run it
- 1
Set the planning horizon
Choose a 12- to 18-month period and define the growth targets the distribution system must support.
Pro tip Use several scenarios when target or market uncertainty is high.
Watch out A horizon shorter than channel-development lead time defeats the purpose.
- 2
Model current channels
Estimate each channel's volume, cost, conversion, capacity, and likely marginal deterioration.
Pro tip Separate temporary volatility from structural saturation.
Watch out Assuming constant efficiency can hide an approaching limit.
- 3
Locate the growth gap
Identify the month in which expected distribution no longer supports the planned trajectory.
Pro tip Express the gap as a range rather than false precision.
Watch out Do not wait for actual growth to reach zero before acknowledging saturation.
- 4
Work backward from lead time
Estimate how long a new channel will take to become reliable and set an investment trigger before the projected gap.
Pro tip Include experimentation, hiring, content, and learning time.
Watch out New distribution rarely becomes predictable immediately.
- 5
Start before the crisis
Launch channel experiments when the trigger is reached while existing channels are still producing growth.
Pro tip Protect a dedicated exploration budget from short-term reallocation.
Watch out Healthy present performance can create false confidence.
- 6
Reforecast continuously
Compare actual outcomes with assumptions and update saturation timing and investment priorities.
Pro tip Review the model on a fixed cadence with channel owners.
Watch out A stale forecast can become as dangerous as having none.
In the wild
A company forecasts that rising acquisition costs will make paid social insufficient in nine months. It estimates that a partner channel needs six months to test and stabilize, so it begins partner experiments immediately rather than waiting for paid growth to fail.
→ A replacement distribution path has time to mature before the projected shortfall.
Common mistakes
Forecasting without a trigger
A model that predicts saturation but does not specify when investment begins remains passive reporting.
Waiting until growth disappears
Once a company is visibly out of growth, it may lack enough time to build a predictable new channel.
Is it for you?
Best for
It is best for companies dependent on a limited number of maturing acquisition channels.
Not ideal for
It is not ideal as a precise prediction in businesses with no usable baseline data, though scenario ranges can still help.
From the transcript
“The other thing that people struggle with is know when when is the time to invest in your distribution challenge or trying to find new…”
“So I need to have like a 12-month plan, an 18-month plan where I forecast my growth so I can start to see where I…”
“And you don't have the time to resolve that, right? And so if you build forecast models, you you can start to figure that out.”
