عرض عملي: الدفاع عن تصميم أمام جمهور تقني معادٍ، والتعامل معه

خطوة بخطوة

1. Prepare: list the five weakest points (ERP coupling, eventual consistency of stock, vendor lock-in, cost, migration risk) and the evidence for each.
2. Open with a concise structure and the key decisions; invite the panel to challenge.
3. Planned mistake: answer the claim "your stock sync will oversell" with "it will not happen". Fix: state what is measured (test results), what is assumed (peak order rate), and the trade-off (reservation window versus availability), then agree a follow-up test.
4. Concede a valid point (retry behaviour missing in the contract) and record the design change.
5. Keep calm on personal remarks: restate the technical question and answer that.
6. Close by reading back the challenges, the answers given, and follow-ups with owners and dates.
