+**Drop 6 – Roadmap & ROI: Your First 90 Stores**
+*Series capstone: “Edge Renaissance—putting compute (and the customer) back where they belong.”*
+
+---
+
+### ☕ Executive espresso (60‑second read)
+
+* **Three phases, ninety stores, one playbook.** Pilot (≤5), Prove (≤30), Scale (≤90).
+* **ROI is real—and fast.** 100 ms faster + higher uptime → +\$X M revenue; hardware amortizes in \~18 months.
+* **Govern once, repeat everywhere.** Immutable builds, GitOps, patch waves. Treat each store like a tiny region.
+* **Message to the board:** “We’re not reinventing—just putting compute back where customers are.”
+
+---
+
+## 1️⃣ The 0‑5‑30‑90 rollout map
+
+```
+PHASE 0: Prep (4–6 weeks)
+Goal: Tooling, golden images, KPIs defined
+Outputs: Git repo, CI/CD, BOM finalized, latency baseline
+
+PHASE 1: Pilot 5 (6–8 weeks)
+Goal: Prove CX & $ impact with 2 workloads (e.g., /inventory API + image cache)
+KPIs: TTFB ↓100 ms, conversion ↑≥5%, no POS downtime during WAN blips
+Deliverables: Exec brief, ops runbooks, security sign‑off
+
+PHASE 2: Prove 30 (8–12 weeks)
+Goal: Add 2–3 more edge workloads (vision AI, promos), test patch waves
+KPIs: Cache hit ≥90%, alert MTTR <15 min, patch drift ≤N‑1
+Deliverables: Audit evidence automation, SLO dashboard, budget ask for scale
+
+PHASE 3: Scale 90 (12–16 weeks)
+Goal: Industrialized rollout kit; 3 waves of 30 stores
+KPIs: 95% stores on latest bundle, <0.1% rollback rate
+Deliverables: Playbook v1.0, board update, expansion roadmap (300+)
+```
+
+---
+
+## 2️⃣ Quick‑math ROI you can defend
+
+**Inputs (example):**
+
+* Online revenue = \$500 M/year, base conversion 2.5%
+* Latency cut = 100 ms → +7–8% conversion (industry studies)
+* Cap‑ex per store cluster (Good/Better tier) = \$5–6 k (4‑yr life)
+* CDN/egress avoided = \$0.045/GB × 100 TB/mo ≈ \$4.5 k/mo
+
+**Back‑of‑napkin:**
+
+```
+Revenue lift:  $500M × 7% = +$35M/year
+Hardware:      90 × $6k =  $540k  (=$135k/yr amortized)
+CDN savings:   ~$54k/yr (after expansion)
+ROI (Year 1):  (~$35M + $54k) / $675k ≈ 51×
+```
+
+*Swap in your numbers; the order of magnitude rarely changes.*
+
+---
+
+## 3️⃣ People & process: who does what?
+
+```
+CORE EDGE PLATFORM SQUAD (8–10 FTE)
+• Platform Lead (1) – roadmap, budget, exec comms
+• SRE/Automation (2–3) – CI/CD, GitOps, patch waves
+• Security/Compliance Eng (1–2) – policy as code, audits
+• Edge App Owners (2–3) – /inventory API, promos, vision AI
+
+REGIONAL / STORE TECH PARTNERS (as‑needed)
+• “Smart hands” for racking, swaps
+• Local networking tweaks
+
+BUSINESS STAKEHOLDERS
+• Digital Product, Merch, Ops – define the CX wins
+• Finance – track realized savings & uplift
+```
+
+> **Rule:** Central team builds the pattern, sites pull it. No snowflakes.
+
+---
+
+## 4️⃣ Operate like a cloud, even if it’s a closet
+
+**Your top 6 SLOs (track weekly):**
+
+1. **TTFB p95 (ms)** for key endpoints (PDP image, `/inventory`)
+2. **Cache hit rate (%)** on Varnish/Nginx
+3. **POS/API latency (ms)** during WAN events
+4. **Patch drift (# stores on N‑2 or older)**
+5. **Backup success rate (%)** (PBS snapshots)
+6. **MTTR for node failure (mins/hours)**
+
+Dashboards: Grafana/Loki summaries pushed centrally nightly; alerts on trends.
+
+---
+
+## 5️⃣ Board‑ready narrative (5 slides)
+
+1. **Why now:** Latency is a silent tax; we’re over‑spending on cloud/CDN; Amazon wins on speed.
+2. **What we’re doing:** Put compute and delivery where customers are—stores & DCs—using Proxmox on commodity gear.
+3. **Proof:** Pilot results—100 ms faster → +X% revenue, \$Y saved in egress, 0 outages on WAN loss.
+4. **Plan & risk:** 0‑5‑30‑90 rollout, governance pillars, automated compliance.
+5. **Ask:** \$Z cap‑ex, 10 FTE cross‑functional team, payback <18 months.
+
+---
+
+## 6️⃣ Risk register (and the auto‑mitigations)
+
+| Risk                    | Mitigation baked in                        |
+| ----------------------- | ------------------------------------------ |
+| Node dies in peak hours | Ceph 3× replica + live‑migration           |
+| Patch breaks store      | Canary waves + fast rollback via Git tag   |
+| WAN outage              | Local DNS/APIs, queued sync jobs           |
+| Audit fails             | Automated evidence exports; policy‑as‑code |
+| Drift / config sprawl   | Immutable bundles, Git as SOoT             |
+
+---
+
+## 7️⃣ Timeline & dollars (visual you can paste)
+
+```
+Q1  Prep & Pilot (5 stores)       $  75k  (gear + labor)
+Q2  Prove @ 30 stores             $ 180k
+Q3  Scale wave 1 (30 stores)      $ 180k
+Q4  Scale wave 2 (30 stores)      $ 180k
+-----------------------------------------
+YEAR 1 CAP-EX / OPEX              ≈ $615k
+
+Projected Year-1 Upside           $35M+ revenue lift + $54k cost saved
+```
+
+*(Adjust “gear” line if you choose GPU nodes or higher tiers.)*
+
+---
+
+## 8️⃣ This week’s action list
+
+1. **Finalize KPIs & baselines** (latency, conversion, uptime).
+2. **Draft the board deck** with the 5‑slide narrative above.
+3. **Lock the pilot scope**: 2 workloads, 5 stores, 8‑week clock.
+4. **Stand up the repo & CI/CD** (even if empty) to anchor governance.
+5. **Book the Phase‑gate reviews** now (Pilot exit, 30‑store exit).
+
+---
+
+### 🎁 Series wrap & what’s next
+
+* **Appendix pack (on request):** BOM spreadsheet, CI pipeline YAML, audit evidence script.
+* **Office hours / webinar?** If there’s interest, I’ll host a live walkthrough.
+* **Spin‑offs:**
+
+    * “Edge ML Ops: packaging & shipping models to 500 sites”
+    * “From closets to parking lots: EV chargers & edge compute”
+    * “Design patterns for zero‑trust store networks”
+
+> **Thank you for riding along.** This wasn’t about “new tech”—it was about rediscovering what made the Internet (and great retail) work: put value as close to the customer as you can, and don’t pay rent on distance.
