Leadership takeaway
This week (16/03 – 22/03) the team advanced two big restaurant-ops foundations — table split/merge with a Kitchen Display System and the CDC-driven search pipeline on Kafka — alongside a full tax UI across the product catalog and a new landing page.
- Restaurant Ops (KDS & Tables) — Built the Kitchen Display System (stations, tickets, real-time events) plus table split/merge end-to-end, so orders flow cleanly from floor to kitchen.
- Tax System — Full tax UI across products, variants, organizers and merchants, with invoice tax-info wired into the merchant and organizer flows.
- Search & CDC Pipeline — Stood up the Debezium change-data-capture pipeline on Kafka with a dead-letter queue, and broadened search to cover descriptions for categories, devices, merchants and organizers.
- Messaging Backbone — Migrated key flows from BullMQ to Kafka, enabled auto-topic creation, and fixed a roundtrip check that was driving 90% CPU.
- Mobile POS — Fixed USB printing on Android 12+, shipped TestFlight distribution, printer template preview, and drag-to-reorder receipt items.
- Authorization — Policy-definition UI with grant/revoke for users, roles, merchants and organizers.
- Landing Page & Branding — New marketing landing page with applied design, imagery, a Vietnamese version, and a new "devglow-ember" theme.
- QA Foundation — Test environment onboarded with Playwright and AI-agent testing.

Delivery
| Metric | This Cycle | Last Cycle (WK11) | 4-Cycle Avg | Target | Status |
|---|---|---|---|---|---|
| Committed | 32 | 27 | 26.3 | — | — |
| Completed | 30 | 24 | 23.5 | — | — |
| Completion % | 93.8% | 88.9% | 89.9% | 85% | OK |
| Cancelled | 2 (6.2%) | 3 (11.1%) | 2.75 (10.5%) | <7% | OK |
| Carried over | 0 (0%) | 0 (0%) | 0 (0%) | <10% | OK |
| Throughput/member | 3.75 | 1.85 | 2.17 | 2.0 | OK |
Misses: None on finalized metrics. However, 19 items were de-scoped mid-sprint. If counted against original 51 committed, completion would be 58.8% — well below 85% target.

Carry-Over Analysis
| Item | Identifier | Assignee | Age (weeks) | Recommendation |
|---|---|---|---|---|
| (none in finalized cycle) | — | — | — | — |
19 items were removed from cycle before close. These should be tracked in WK13 to verify they didn't become zombies.
Age rules reminder:
- >= 3 weeks: MUST split or cancel (no exceptions)
- 2 weeks: review with assignee, split if > 50% remaining
- 1 week: transfer to next cycle, keep assignee

Blockers & Risks
| Risk | Impact | Mitigation | Owner |
|---|---|---|---|
| 19 items de-scoped mid-sprint — masks real completion rate | High | Audit WK13 for inflated carry-over load | phat.nguyen |
| Khoa Nguyen consistently overloaded (10 this week, 12 last week) | High | Cap at 5 items, redistribute to underloaded members | PM |
| 5 members had items assigned but completed 0 (all transferred out) | Med | Clarify commitment at sprint start | PM |
| NXET-436 lingered 9 weeks before cancellation | Low | Triage items > 3 weeks old weekly | PM |
4-Cycle Trend
| Metric | WK09 | WK10 | WK11 | WK12 | Direction |
|---|---|---|---|---|---|
| Items completed | 16 | 24 | 24 | 30 | ▲ |
| Completion % | 94.1% | 82.8% | 88.9% | 93.8% | ▲ |
| Avg items/member | 1.07 | 2.0 | 1.85 | 3.75 | ▲ |
| Carry-overs | 0 | 0 | 0 | 0 | ■ |
| Health Score | 78 | 75 | 76 | 76 | ■ |
Forecast (Monte Carlo)
Based on last 4 cycles of throughput (avg 23.5 items/cycle, 8-15 active members):
| Milestone / Module | Remaining Items | 50% confidence | 85% confidence |
|---|---|---|---|
| WK13 (27 committed) | 27 | Mar 29 | Mar 29 |
Throughput trending upward (30 completed vs 23.5 avg). WK13 has 27 items committed — achievable at current pace if workload is balanced and de-scoped items from WK12 don't inflate WK13 mid-sprint.
Action Triggers
| Condition | Fired? | Action |
|---|---|---|
| Completion < 75% for 2 consecutive cycles | No | — |
| Completion > 95% for 2 consecutive cycles | No | — |
| Any member > 5 items | YES — Khoa (10), Hai Cao (6) | Redistribute before next sprint |
| Any member < 70% done for 2 cycles | No | — |
| Carry-over item age > 2 weeks | YES — NXET-436 (9 weeks, cancelled) | Already cancelled; audit other aged items |
| Cancellation > 15% | No (6.2%) | — |
| Workload max/min ratio > 3x | YES — 10:1 ratio | Rebalance assignments |
| Health Score < 60 | No (76) | — |
Recommended actions for WK13:
- Cap Khoa Nguyen at 5 items max — redistribute surplus to duc.bach, kien.truong, phat.chung
- Audit the 19 de-scoped items — verify they landed in WK13 with proper assignees and aren't becoming zombies
- Confirm capacity with phat.nguyen, thuong.nguyen, viet.vo, hieu.vo, tung.ma before assigning WK13 items
