Every product has a ground-zero unit of value. This is not a design preference—it is Dependency Logic. If Feature B depends on Feature A, building both at once introduces technical noise. We isolate the foundation so your feedback is 100% interpretable.
Booking product → the user must be able to apply.
Community → the user must be able to create a profile.
Task guide app → the user must be able to upload.
Notification system → users must be willing to give their email.
If this foundation does not work, nothing else can be validated.
This is why the methodology scopes MVPs around the ground-zero action first and always. This is not a design preference — it is engineering logic.
If Feature B depends on Feature A, you cannot build both at once and expect clean feedback.
A→validate A→THEN build B
When this step is skipped, you lose the ability to diagnose problems. For example, if you ship email + notifications together and something breaks, you cannot tell:
- • Did users refuse to give their email?
- • Did the email storage break?
- • Did the notification service break?
- • Did the notification logic interfere with email submission?
You lose all clarity.
The methodology avoids this failure mode entirely. Each version of the product is designed to answer a single yes/no question:
- Does the core action work?
- Do users adopt it?
- Does it create value?
