Help Guide - External Factors
When we talk about External Factors in Growzz, we’re talking about the forces that will influence your plan regardless of the actions taken by the supplier account team and the retailer merchant team managing the plan.
These are factors outside the normal day-to-day control of the buyer, merchant, supplier account team, or broker building the plan together.
They are not promotions.
They are not pricing decisions made within the plan.
They are not investments you choose to make inside the planning process.
They are broader realities that can affect demand, supply, sales, margin, or execution.
That distinction matters.
Some external factors may still sit within the wider control of either organisation. For example, a supplier may decide at corporate level to close a factory for three months to refit a production line. A retailer may decide to open new stores.
That is inside the supplier’s and retailer's wider control. But it is outside the direct control of the account team and merchant team woring together.
So within Growzz, these should still be treated as external factors.
This step is important because strong planning separates what the account and merchant team can directly shape from what they must plan around.
Before building External Factors, ask one key question: What is likely to happen outside the day-to-day control of the supplier account team and retailer merchant team that will still affect performance?
There are several common types of external factors.
First, structural market trends.
A category may be growing, slowing, or declining over time. Consumer behaviour may be changing.
Those shifts can affect your results even before you make any commercial moves.
Second, retailer or supplier business changes outside the trading teams’ control.
New store openings.
Factory shutdowns.
Capacity constraints.
Channel expansion.
These can materially alter performance without being caused by the plan itself.
Third, regulatory or macroeconomic changes.
Taxes.
Legislation.
Inflation.
Economic pressure.
These can influence pricing dynamics, affordability, or demand patterns.
Fourth, known one-off events.
Supply disruption.
Competitor exits.
Major market shocks.
Unexpected but identifiable events that should be reflected if they are credible and material.
The key principle is realism.
If you ignore external factors, your plan can become distorted. You may wrongly credit yourself for growth the market would have delivered anyway. Or wrongly blame your activity for declines caused by external pressure.
Next, think about evidence.
Good external factors are grounded in data, not opinion. Use retailer insight, market data, historical patterns, known commitments, or credible forward-looking signals.
Then think about scale.
External factors should be meaningful, but not exaggerated. Small noise does not need to become a planning assumption. Focus on what is material enough to influence decisions.
You should also think about timing.
Some changes happen gradually. Others hit suddenly. Some begin mid-year.
A good plan reflects when the impact is likely to occur, not just the total size.
Finally, remember that this step is for factors outside the day-to-day control of the supplier account team and retailer merchant team.
If you are planning a promotion, a price move, added distribution, or in-store support, those belong in the relevant Growzz planning steps instead.
Successful External Factors create a realistic starting context for the rest of the plan. That is how you build forecasts and decisions on reality, not wishful thinking.
Here are the key takeaways
External Factors sit outside the day-to-day control of account and merchant teams.
They may still be controlled elsewhere in the wider organisations.
They separate controllable actions from factors teams must plan around.
Use evidence-based assumptions with realistic timing.
Strong plans are based in reality.
