Week	Focus	Gate	Signal
1	Map customer owners + outcome statement for Customer Strategy Ultimate Guide 2026: With 90-Day Plan	experiment kill criteria	Decision clarity score >= 60/100

Scope lock for “Customer Strategy Ultimate Guide 2026: With 90-Day Plan”

This page is intentionally narrow. It covers Customer / Strategy under limited specialist bandwidth, using growth experiment portfolio design as the primary operating lens.

It does not try to replace a full Business curriculum. If you need adjacent topics, use the cluster links below after finishing the checklist.

Operating framework for Customer

1) Scope for Customer/Strategy

Write one sentence for the business outcome behind Customer Strategy Ultimate Guide 2026: With 90-Day Plan. List constraints (limited specialist bandwidth). Reject work that does not serve the sentence.

2) Ownership map

Assign planning, production, QA, and measurement owners. Publish the map where the team already works.

3) Control stack

• experiment kill criteria (entry gate)
• budget variance alerts (delivery gate)
• capacity planning checkpoint (review gate)

4) Delivery rhythm

Ship in small increments. After each release, add links to the Business hub and sibling cluster pages.

5) Learning loop

Compare planned vs actual every week. Keep, fix, or stop. Do not expand while experiment kill criteria is failing.

2. Uses experiment kill criteria as a quality gate.
3. Ties weekly work to Contribution Margin Clarity.
4. Connects to the broader Business cluster so pages reinforce each other.
