OEM experience
Automotive Supplier Consulting
TierSum brings OEM-level expertise — forged at Tesla, Ford, and FCA — directly to struggling automotive suppliers. Not legacy playbooks. Not outdated methodology. Real solutions built for today's supply chain.
Why TierSum
"Most consultants bring the same playbook that failed suppliers ten years ago."
— TierSum approach
Built inside OEMs, not outside them
Experience from Tesla, Ford, and FCA means understanding what OEMs actually demand — from quality systems to program delivery cadence — not what textbooks say they want.
Next-generation methodology
Lean 2.0, digital quality systems, agile program management, and data-driven root cause analysis — not the legacy frameworks that legacy consultants recycle.
On-site, in the plant
TierSum works on the floor, not from a PowerPoint deck. Real change happens where the problem lives — in the production cell, on the line, in the quality lab.
Services
TierSum embeds directly with automotive suppliers to diagnose, stabilize, and transform the operations holding them back from OEM expectations.

05
Logistics & Supply Chain
Stabilize inbound and outbound logistics, and build sequencing and inventory systems that match actual OEM pull rates.
06
Program Management
Lead or recover new program launches — from tooling readiness and PPAP submission to SOP and launch monitoring — using OEM-aligned program cadence.
Background
TierSum's consulting methodology isn't borrowed from industry frameworks. It was built through years of direct experience inside the OEMs that set the standards suppliers are judged against.
Tesla
Manufacturing & Quality Operations
Inside the fastest-moving manufacturing environment in the automotive industry — where iteration speed, first-principles problem solving, and ruthless efficiency define how work gets done. Built a foundation in modern quality and process that legacy OEMs are only beginning to adopt.
Ford
Program & Quality Management
Deep exposure to Ford's global supplier quality and program management infrastructure — understanding exactly what Ford requires from Tier 1 and Tier 2 suppliers at every stage of a program lifecycle, from sourcing through PPAP to launch.
FCA / Stellantis
Operations & Process Engineering
Hands-on manufacturing and process experience within one of the world's largest automotive groups — building cross-platform knowledge of production systems, quality culture, and operational turnaround in high-pressure environments.
Our approach
TierSum doesn't parachute in with a pre-written report. We embed, diagnose, and fix — then leave you with systems that sustain.
Step 01
Rapid assessment
On-site plant visit within days of engagement. We map the current state — production, quality, logistics, program health — and identify the highest-impact areas to address first.
Step 02
Embedded stabilization
TierSum works on the floor alongside your team. Containment actions, immediate process corrections, and daily cadence meetings to stabilize the most critical issues within weeks.
Step 03
Systemic improvement
Root causes addressed. Control plans updated. Quality systems rebuilt. New processes documented and validated. We don't stop at containment — we fix what caused the problem.
Step 04
Sustainable handoff
Training your team on the new standards, monitoring systems, and escalation processes — so the gains hold after TierSum leaves. Our goal is making ourselves unnecessary.
