Weekly Exec Update — 1 pager

Week of: 2026-01-01
Program health (RAG): 🟡

1) Headlines (top 3)

  • Baseline established + critical path confirmed: Project start is 2026-01-02 with 125 days total duration. Critical path is T001 → T010 → T050 → T070 → T080 → T100 → T110 → T120 (Charter → Requirements → HW Design Freeze → EVT Build → FAT → Install → SAT → Qual).
  • Facilities is the current constraint (0% readiness): Facilities readiness is blocked and remains the most likely driver of install risk unless network/VLAN is cleared (or a compliant temporary workaround is approved).
  • Execution decision needed (controls churn): Controls readiness is 50%; we need to implement a FAT “release lock” (pin PLC/FW/HMI + IO map revision) to protect FAT evidence quality and reduce late integration surprises.

2) Milestones (next 4–6 weeks)

Milestone Plan date Forecast date Delta Owner Notes
Finalize Charter (T001) 2026-01-06 2026-01-06 0d PM Sponsor signoff + publish cadence/RAID
Requirements Baseline (T010) 2026-01-20 2026-01-20 0d Eng Lead Freeze v0.1 requirements + RTM baseline
Site Survey & Utilities Plan (T030) 2026-01-22 2026-01-22 0d Facilities Lead Confirm power/network/utilities; capture constraints
ICD v0.1 Draft (T020) 2026-01-24 2026-01-24 0d Controls Lead Initial IO map + protocols for integration
Long-Lead Orders Placed (T040) 2026-01-16 2026-01-16 0d SCM Confirm supplier commit dates + expedite triggers
Design Freeze (HW) (T050) 2026-02-05 2026-02-05 0d HW Lead Change control mandatory after freeze

3) Critical path blockers

Blocker Domain Owner ETA Escalation needed
Network/VLAN approval not complete (drives Facilities readiness = 0%) Facilities Facilities Lead 2026-01-10 Yes — IT escalation if not approved by ETA
Controls version churn risk before FAT (needs release lock policy before T080) Controls Controls Lead 2026-02-01 Yes — approve “FAT release lock” decision
Supplier lead time uncertainty for long-lead components (risk to T070 EVT build start) HW/Supplier SCM 2026-01-16 Monitor — trigger expedite/alternate sourcing if slip forecasted

4) Top risks (top 5)

Risk Severity Mitigation Owner Due
Facilities network/VLAN approval delays site readiness minimum High Escalate IT ticket; pre-approve compliant temporary isolated network workaround if needed; track weekly Facilities Lead 2026-01-10
Long-lead parts slip build start (impacts EVT build on critical path) High Confirm supplier capacity + commit dates; dual source where feasible; expedite triggers SCM 2026-01-16
Controls release churn causes late integration defects / retest Medium Define FAT release lock; allow changes only via change control + defined retest scope Controls Lead 2026-02-10
Safety interlock validation expands scope late (SAT/commissioning impacts) Medium Pre-test interlock logic; align EHS signoff checklist early; schedule walkdown EHS Lead 2026-01-20
Install window conflict / site access limitations Medium Lock install window; pre-stage tooling; align contractors + site services Ops 2026-03-10

5) Change control summary

  • CRs opened this week: CR-001 (Proposed) — Pin Controls versions for FAT (“release lock”)
  • CRs approved: None
  • Net schedule/cost impact: Expected schedule protection (reduced integration churn). Minimal cost unless emergency retest required.

6) Metrics

  • Readiness by domain: Hardware 100%; Controls 50%; Facilities 0%; EHS 100%
  • Overall readiness: 62%
  • Open Sev-1/Sev-2 issues: Sev-1 0, Sev-2 1 (Facilities network readiness)
  • Supplier OTD for LLTs: Baseline pending; initial PO confirmation due 2026-01-16
