Leadership takeaway
This week (23/03 – 29/03) the team stood up the full staging environment on VNPAY Cloud K8s with the search & CDC pipeline deployed end-to-end, while landing a wave of POS, sale-renderer and table-allocation delivery plus the public landing & legal pages.
- Staging on K8s — Full PMBH staging environment provisioned on VNPAY Cloud Kubernetes, with network policies, egress for the internal load balancer, and a migrate image to bootstrap the database.
- Search & CDC pipeline — Debezium CDC stack and Kafka topic-init job deployed, Typesense tuned for multilingual / embedding search, and the commerce search-and-CDC component enabled.
- Resilient messaging — Background retry loop and reconnect handling for Kafka consumers across finance, inventory, pricing and ledger, hardening against all-broker disconnects.
- Table allocation & sale — AllocationUsage for table management, socket events on order/order-item mutation, and customer loyalty points earned after a paid sale order.
- POS hardware & printing — TCP printer connect, cash-drawer open, codepage select, bill-template save and order-item printing on the device.
- Fare system & sale-renderer — Fare group management UI with a three-column panel and inline rules editor, plus sale-renderer socket wiring and cash-numpad fixes.
- Public site & loyalty — Bilingual privacy and terms-of-service pages, the customer Sale-Customer show screen, and the design-system library scaffold.

| Throughput/member | 4.0 | 3.75 | 3.0 | 3.0 | 3.4 | 2.0 |
Misses:
- Completion at 60.3% — target was 85%. Sprint overloaded at 73 items (2.3x the 4-cycle avg of 40). 12 BE/commerce items bulk-added on 2026-03-26 (3 days before sprint end) inflated committed count.
- Carry-over at 37.0% — target was <10%. Driven by late additions + 5 zombie items (age >= 3 weeks) that should have been split earlier.

Context: Top 4 members are heavily co-assigned, inflating committed counts. phat.nguyen's contribution is underrepresented by item count — the K8s staging setup (NXET-644) and architecture investigation (NXET-596) were high-effort items, plus he identified and triaged 12 commerce bugs forming the WK14 pipeline.

Blockers & Risks
| Risk | Impact | Mitigation | Owner |
|---|---|---|---|
| Invoice refactor (NXET-419) 11 weeks, blocks NXET-449 and NXET-516 | High | Split into smaller deliverables; reassign if viet.vo unavailable | phat.nguyen |
| 12 BE/commerce items added 03-26 inflated sprint committed count | Medium | Add to next cycle directly instead of current sprint | phat.nguyen |
| Bug completion: 7/24 (29%) — most bugs co-assigned but not yet started | Medium | Prioritize bug batch in WK14, assign clear ownership per bug | Team |
| thuong.nguyen POS design (NXET-562) at 2.5 weeks with no clear progress | Medium | Review scope, split WebPOS and HandheldPOS into separate items | thuong.nguyen |
4-Cycle Trend
| Metric | WK10 | WK11 | WK12 | WK13 | Direction |
|---|---|---|---|---|---|
| Items completed | 24 | 24 | 30 | 44 | ▲ |
| Completion % | 82.8% | 88.9% | 93.8% | 60.3% | ▼ |
| Carry-overs | 0 | 0 | 0 | 27 | ▼ |
| Cancellations | 5 | 3 | 2 | 2 | ▲ |
| Health Score | 75.5 | 76.7 | 75.7 | 48.1 | ▼ |
The team delivered a record 44 items (vs avg 26) — actual throughput is increasing. But the sprint was loaded with 73 items, making the completion rate appear poor. Cancellation trend is improving (17% → 3%).
Forecast (Monte Carlo)
| Scope | Remaining | 50% confidence | 85% confidence |
|---|---|---|---|
| WK13 carry-over | 27 | WK14 (2026-04-05) | WK15 (2026-04-12) |
| Invoice track (419/449/516) | 3 (needs splitting) | WK15 (2026-04-12) | WK16 (2026-04-19) |
| BE/commerce bug batch | 12 | WK14 (2026-04-05) | WK14 (2026-04-05) |
Action Triggers Fired
| Condition | Trigger | Recommended Action |
|---|---|---|
| 6 carry-over items age > 2 weeks | Zombie | NXET-419, 449, 512, 516, 532 MUST be split or cancelled. NXET-562 review. |
| Workload max/min ratio = 18:1 | Imbalance | Rebalance — avoid bulk co-assignment, assign clear primary owner per item |
| Health Score 48 < 60 | System issue | Dedicated retrospective required |
Recommendations
- Cap WK14 at ~40 items — 73 was a 2.3x overcommit. Team's proven throughput is ~30-44 items/cycle.
- Stop mid-sprint bulk additions — the 12 BE/commerce items added on 03-26 should go to the next cycle.
- Split the 5 zombie items immediately — NXET-419 (11wk), NXET-449 (10wk), NXET-512 (4wk), NXET-516 (4wk), NXET-532 (4wk).
- Assign clear primary owners — co-assignment inflates workload metrics and obscures accountability. Use 1 primary + reviewers.
- Hold a brief retrospective — health dropped from ~76 to 48. Main driver is sprint sizing, not team performance (throughput is actually up).
