Name the product, channel, unit, period, proposed change, decision owner, and question the separate analysis is intended to inform.
What to include
- product and channel
- proposed change
- decision owner
Document the observed baseline
Identify current records for price or net revenue, product cost, channel costs, volume, timing, and exclusions. Keep missing observations visible.

Define one proposed change
State one changed cost, price, fee, promotion, logistics, or other assumption with source, effective date, and accountable owner.

- unit and currency
- period and treatment
Separate variable, fixed, shared, and allocated scope
Record which costs vary with units, remain fixed or shared, are allocated, or stay outside the analysis.
What to include
- variable items
- fixed or shared items
- allocation and exclusions
Keep volume and timing hypothetical
Label projected units, demand response, implementation timing, ramp, duration, and reversibility as assumptions.
What to include
- volume assumption
- timing assumption
- hypothetical label
Record dependencies, uncertainty, and exclusions
Document contract, customer, operational, capacity, service, quality, data, attribution, and market uncertainty plus explicit exclusions.
What to include

- exclusions
Prepare the analysis handoff
Name the owner method or separate finance model, required reviewers, source gaps, unresolved questions, and decision date.
What to include

How this page fits the Tools system
The Channel Contribution Margin Planner may execute CHANNEL-CONTRIBUTION-V1 for one reviewed scenario; this guide owns baseline/change assumption discipline only.
The guide ends with a baseline/change assumptions packet, not margin impact, price impact, cost impact, volume response, break-even, demand, revenue, savings, ROI, or a pricing or channel decision.
What this page does—and does not—show
This guide organizes baseline and change assumptions for a separate review. It does not calculate margin impact, price impact, cost impact, volume response, break-even, demand, revenue, savings, ROI, or a pricing or channel decision.
The Channel Contribution Margin Planner may execute CHANNEL-CONTRIBUTION-V1 for one reviewed scenario; this guide runs no scenario and subtracts no result.
Evidence and review boundary
Tier B. This guide organizes baseline and change assumptions for a separate review. It does not calculate margin impact, price impact, cost impact, volume response, break-even, demand, revenue, savings, ROI, or a pricing or channel decision.
Commercial and finance owners, with accounting, sales, operations, procurement, customer, legal, or executive review appropriate to the proposed change.
