Marsh Industries — Kickoff Notes
Quick notes from the pre-kickoff with Linda (Marsh Ops). Pilot scoped to one extrusion line; Priya is running the engagement, Tomas owns the build.
Kickoff lands Tuesday May 6 on-site in Coventry — half-day floor walk, half-day whiteboarding. Pilot has to be live on Marsh's shop floor by August 18, which is the maintenance window before their Q4 ramp.
Tooling: we agreed to standardise on Siemens S7 PLCs across the pilot — Linda's team already has spare parts and two engineers certified, so the cost of fighting that is higher than the cost of accepting it. Trade-off: we lose the Beckhoff option for the realtime layer. Tomas is fine.
Scope cut: no mobile dashboard in v1. Floor supervisors are at fixed terminals, and chasing a responsive build would eat two weeks we don't have. Revisit post-pilot.
Hard constraint everyone needs to internalise: any control-loop change has to clear ISO 13849 functional-safety sign-off before it touches the line. Marsh's safety officer is the gate. Build the review step into the deploy pipeline from day one — retrofitting it is what killed the last vendor.
Action before kickoff: Tomas to survey Line 3 sensors and flag anything older than 2019 — Linda suspects two of the load cells are drifting and wants them on the replace list before we commit to telemetry baselines.
