A result hides the path that produced it
A polished before-and-after image may show change, but it does not show the sequence of decisions, delays, tradeoffs and corrections that made the result possible. A chronological project record preserves the parts that are most useful for learning.
Record context at the moment of the decision
Each update should state what was known, what was uncertain and why the next action was selected. Later information should be added as a new update rather than quietly rewriting the earlier record.
- Date the update and identify the stage of work.
- Separate observed conditions from estimates or expectations.
- Note the next checkpoint and the question it should answer.
Make corrections part of the story
A change in direction is useful information when the reason is documented. Showing how an assumption was tested and revised creates a more credible learning record than presenting every step as inevitable.
