This method treats process migration as a sequence of bounded experiments rather than a single company-wide switch. Managers map an end-to-end workflow into sections such as onboarding, vendor selection, scheduling, and fulfillment. They then compare the current and proposed approach for one section, test the new version under real conditions, identify where information or responsibility falls through, and repair those weaknesses. Only after that section works does the team move to the next one. When every section has been validated, leadership retires the old workflow, announces the complete replacement, and obtains visible acknowledgment from everyone affected. The approach preserves live operations, limits the blast radius of mistakes, and creates factual accountability about which procedure is current.
Origin
Jasmine Star described using this method when managers had to maintain active operations while constructing a replacement system. Extracted from The Jasmine Star Show.
Core principles
- 01Keep current operations running while designing their replacement
- 02Break complex workflows into testable sections
- 03Fix observed failures before expanding the rollout
- 04Declare one authoritative process after the full migration
- 05Require visible acknowledgment of changed procedures
How to run it
- 1
Map the operating sequence
Divide the full workflow into discrete, ordered sections with clear boundaries. Identify the people, information, technology, and outputs involved in each section.
Pro tip Use natural handoffs such as onboarding, selection, planning, and fulfillment as section boundaries.
Watch out Sections that are too broad make it difficult to locate the source of a failure.
- 2
Design the first replacement
Document how the first section works today and specify how it should work in the new system. Preserve useful elements rather than assuming every detail must change.
Pro tip Ask what can be automated and who must be included in each communication.
Watch out Do not redesign the entire workflow before learning from the first live test.
- 3
Pressure-test it
Run the proposed section during real or realistic work and observe where tasks, details, or communications fail. Capture facts about each breakdown rather than relying on general impressions.
Pro tip Test edge cases and handoffs, not only the ideal path.
Watch out A process that looks complete on paper may still fail when ownership changes hands.
- 4
Repair and standardize
Fix the observed gaps and declare the validated section to be the approved way of working. Document its order of operations and communication requirements.
Pro tip Make one manager accountable for resolving ambiguities before the section is locked.
Watch out Leaving both old and new variants available invites people to revert under pressure.
- 5
Advance through the workflow
Repeat the design, test, repair, and standardize cycle for each remaining section while the existing operation continues. Integrate each approved section into the emerging end-to-end system.
Pro tip Monitor the boundaries between validated sections as carefully as the sections themselves.
Watch out Local improvements can create downstream problems if their handoffs are not retested.
- 6
Complete the re-buy-in
Once the full system is ready, announce that the former process and KPIs are retired. Require each affected person to acknowledge that they saw and understood the new procedure.
Pro tip Use a shared post, response, or reaction to create a searchable acknowledgment record.
Watch out A broadcast message without confirmed receipt does not establish shared understanding.
In the wild
A service team divides client delivery into pre-client onboarding, vendor selection, timeline creation, and fulfillment. It tests the new onboarding method first, repairs missed details, and standardizes it before moving to vendor selection. After every section is validated, the team announces the completed workflow and retires the old KPIs.
→ The company improves its delivery system while managers keep active client work moving.
A marketing team separates intake, briefing, production, review, and publishing. It trials a new briefing template on several live assignments, fixes unclear ownership, and then progresses section by section. When the full sequence is stable, everyone acknowledges the new process in the shared communication channel.
→ The team changes its workflow with fewer disruptions and a clear record of adoption.
Common mistakes
Replacing everything at once
An all-at-once migration creates too many simultaneous failure points and makes diagnosis difficult.
Testing only the happy path
A system is not pressure-tested unless the team examines handoffs, missing information, and unusual cases.
Skipping explicit re-buy-in
People may continue using the retired process if leaders never confirm that each person received the change.
Is it for you?
Best for
It is best for managers redesigning recurring workflows while the existing business must continue serving clients.
Not ideal for
It is not ideal for emergency changes that must be implemented everywhere immediately.
From the transcript
“And so you're just pressure testing each part of the system.”
“So pressure testing, each part of it, announcing when the whole thing is changed and making sure that everybody.”
“And so this is what we call like a re offer or rebuy in like we make people respond in slack or communication. Yes, I…”
