How knowledge accumulates
A delivery should not leave useful experience trapped in a completed task. Accumulation preserves understandable, reusable knowledge while allowing new evidence to correct earlier assumptions.
Retain sources and decisions
Record needs, references, reasons and constraints as well as the result. This helps a new participant understand why a choice was made instead of seeing only a polished final artifact.
Form reusable units carefully
Repeated problems may become checklists, components, processes or articles. Preserve applicable conditions: a method that helped one engagement does not automatically become a rule for every situation.
Connect versions and feedback
Relate material changes to previous versions and reasons. Feedback, failed tests and new information should inform corrections rather than being removed to make the history look uniformly successful.
Reassess with new evidence
Methods and tools change. Review sources and conditions, retaining useful knowledge and clearly identifying content that a later version has replaced.
