Judgement

Good judgment comes from responsibility

• Rather than attaching something to the product, you should start by extracting what should be there

• Making long-term judgments from the product's perspective, without ego

• Clear verification for error correction

• Apply changes only to where the assumption of error occurrence has been infringed, where it needs to be corrected, and at least where it is intended

• You need to infer things that you can't see directly by clearly seeing the context
