1. Own it — no excuses, no blaming others
2. Explain the cause honestly (often: underestimation or hidden complexity)
3. Describe how you communicated early and contained the impact
4. End with the concrete habit you changed
コミュニケーションが極めて重要です。早期に報告した納期遅延は予期しない遅延とは全く異なります。
実践例

S: I committed to a reporting feature in one sprint.
T: Midway I realized the data source was messier than expected.
A: As soon as I saw the slip, I told my lead, gave a revised estimate, and
shipped a smaller working version first.
R: We delivered the full feature a few days late but with no surprises. Now I
add a buffer for any task that touches unfamiliar data.
