ChainForm · Supply Chain Engineering for Service Organizations

Uptime is won in the parts wait.

ChainForm designs the service networks, cross-border lanes and vendor systems behind the availability you sold. Not a deck. A network that holds when a machine goes down in a country you have never shipped to.

Same technicians, same machines. Most restore time is not repair, it is waiting for a part to clear a border, a warehouse or a courier cut-off. That is the part I engineer.

Detect and diagnose. The clock starts at failure, not at the ticket. Monitoring and entitlement data decide how much of it you lose before anyone moves.

Decide and dispatch. Who is entitled to what, which engineer, which part number. This stage is data quality wearing an operations costume.

Travel and access. Distance is only half of it. Site access windows, permits and cleared personnel decide whether the engineer can start once they arrive.

Parts wait. The largest and most compressible block. Stocking position, customs routing and courier cut-offs decide it, and all three are designable.

Fix and test. The only stage your engineers fully control, and usually the one already running well. Which is exactly why the hours are not here.

01  The problem

You sold 4 hour response in 22 countries. Operations got the invoice.

Service contracts are written by people who price risk, and executed by people who move boxes. The gap between those two rooms is where availability quietly dies: a part sitting in customs in São Paulo, a courier that does not serve the industrial park, an importer of record nobody arranged, a spare stocked two thousand kilometres from the only machine that needs it.

The fix is rarely a new carrier or a new system. It is a network that was designed for time to restore, with the compliance and vendor layer built to match. That is an engineering job, and it is the only job ChainForm does.

02  Services

Six things I build.

Each one is scoped, fixed price where possible, and ends in a document your team can operate from. No retainer required to start.

S1

Service network design

Where stock sits, at what tier, and how far it is from the machines that matter. Sites ranked by downtime tolerance, not by map convenience.

You getNetwork model, forward stocking location shortlist, stocking policy by criticality tier, cost versus time to restore trade curve.

4 to 6 weeks
S2

Cross border lanes and compliance

Importer and exporter of record structures, customs routing, licensing, fiscal representation, and the destinations that quietly break every plan.

You getLane design per country, compliance route and entity structure, vendor set, landed cost model, restricted destination playbook.

3 to 6 weeks
S3

Vendor sourcing and 4PL orchestration

Run the tender end to end. Build the vendor set, normalize buy costs that arrive in five incompatible formats, and end single carrier dependency.

You getRFQ pack, comparable cost pool, weighted scorecard, award recommendation, SLA schedule and governance cadence.

4 to 8 weeks
S4

SLA and entitlement engineering

Turn availability commitments into terms your operation can actually deliver and your finance team can actually measure.

You getEntitlement matrix, SLA and KPI definitions, credit and penalty logic, coverage feasibility check before you sign.

2 to 4 weeks
S5

Service data and visibility

Dispatch fails on missing data long before it fails on logistics. Fix the data spine, then add real time tracking that answers a useful question.

You getService data model, tracking and IoT design, first time fix diagnostics, KPI scorecard and dashboard specification.

3 to 5 weeks
S6

Fractional supply chain lead

Senior supply chain capacity for teams that need the judgement without the headcount. I sit in your governance calls and own the decisions.

You getFixed days per month, vendor and escalation ownership, monthly performance review, direct line for the urgent ones.

Monthly

03  Method

Diagnose before designing. Always in that order.

Every engagement runs the same four stages. Most clients start at stage one and decide about the rest with the findings in hand.

Stage 01

Diagnose

Two weeks, fixed fee. I take your contracts, your last twelve months of service events and your vendor invoices, and show you where the hours and the money leak.

Stage 02

Design

The target network on paper: stocking tiers, lanes, compliance structure, cost and time to restore modelled against the commitments you actually signed.

Stage 03

Source

Tender, negotiate and award the vendors that execute the design. Comparable numbers, a scorecard, and terms written to be enforced.

Stage 04

Stand up

Go live with a runbook, escalation paths and a scorecard your team owns. I hand over rather than build a dependency.

Typical full arc: 3 to 6 months · Stage 01 alone: 2 weeks

04  Engagements

Three ways to work together.

Priced on scope, not on hours logged. You will know the number before we start.

Start here

Assessment sprint

Two weeks, fixed fee. The fastest way to find out whether your service network is the problem.

  • Network, lane and vendor teardown
  • Quantified leak list, ranked by hours and dollars
  • Ninety day action plan
  • Credited against a follow on project

Scoped work

Project

One of the six services above, or a combination, delivered to a fixed scope and a fixed date.

  • Written scope and deliverable list
  • Fixed price, milestone based
  • Weekly working session with your team
  • Handover pack at close

Ongoing

Fractional lead

Named senior supply chain ownership on a monthly retainer, for teams building the function as they go.

  • Fixed days per month
  • Vendor governance and escalations
  • Monthly performance review
  • Three month minimum, then rolling

05  About

ChainForm is Eyal Yossef.

I spent my career on the operator side of field service supply chain, most recently as VP Supply Chain Solutions at a Gartner recognised fourth party logistics provider, designing and running service parts networks for original equipment manufacturers in medical devices, network infrastructure and industrial equipment.

Every uptime promise is a logistics commitment wearing a commercial suit. Someone has to make the logistics true.

06  Questions

How does a first engagement usually start?
A thirty minute call, no charge, where you describe what is breaking. If it is something I can fix, I send a one page scope and a price within two working days. Most clients begin with the two week assessment sprint.
Do you take over our logistics operation?
No. I design the system, run the tender, and hand it to your team with a runbook. If you want ongoing ownership, that is the fractional lead retainer, which is a defined number of days per month rather than an outsourcing arrangement.
We already work with a 3PL or 4PL. Is this a conflict?
Usually the opposite. I work on your side of the table, which includes holding your existing providers to the terms they signed. Where a provider is genuinely the right one, the engagement becomes about governance rather than replacement.
How do you price?
Fixed price per scope wherever the scope can be defined, which is most of the time. Retainers are a fixed monthly fee for a fixed number of days. Travel and third party costs are passed through at cost, agreed in advance.
Can you work in our region?
Yes. The work is remote first with on site time where a network decision needs eyes on the ground. I operate across Europe, the UK, North and South America, the Middle East, Africa and Asia Pacific, and I have spent a lot of time in the customs regimes that people find surprising.
What do you need from us to start?
Your service contracts or SLA terms, twelve months of service event data in whatever shape it exists, your current vendor list and rates, and one hour with the person who gets the escalation calls. That is enough for a useful diagnosis.

Tell me what is breaking.

A missed SLA, a country you cannot ship into, a vendor you cannot compare, a network you inherited and never trusted. Thirty minutes, no pitch. If it is not my kind of problem I will say so and point you somewhere better.
