VCDesign
(Value Continuity Design)
VCDesign (Value Continuity Design).
Defining design principles not for "how to build", but for how to protect the value after creation over
time.
VCDesign Constitution
This system is deemed to have lost its value of existence
the moment humans can no longer explain the reason for its existence.
Even if this implementation is erased by AI tomorrow,
is the 'value of the judgment' we made today
ready to be inherited by the next code?
What is this specification for?
VCDesign is a set of specifications not for "how to build" a finished system, but for
how to design so that a system's value does not get lost over time during operation.
"Sustaining value" means embedding this obvious cycle into design:
- Clarify the expected value at design time
- Check whether the current state still preserves that expectation
- If it doesn't, improve it. If you can't, let it go.
2026 Implementation (value-review, VC-AD, TDDD)
- Define system value (Planning): value-review Fix value and boundaries centered on the Value Review Sheet
- Boundary definition to maximize AI (Design): VC-AD A map of boundaries often missed in the AI era
- Use conversational AI and auto code generation (Development): TDDD A practical development operating record in the AI era
Diagnostics
A set of questions to confirm "where you take responsibility" for systems.
Use this as a self-check for design soundness.
