> 溫故而知新，可以為師矣。

The passage connects revisiting prior learning with gaining new understanding.

## Editorial interpretation

Turn past experience into a new question

Use differences between past and present conditions to formulate a new question instead of simply repeating an old solution.

## Business application

When retrospective documents accumulate without changing the next project.

1. Extract an observed result and its original conditions from one past project.
2. Choose one condition that differs today and test whether it changes the outcome.

Deliverable: A short note linking past evidence, changed conditions and the next test.

## Limits

A past success does not guarantee success under different conditions. Separate observations from retrospective explanations.

## Validation question

Did reflection produce a new, observable question?
