Launching a production machine is not one event. A structured manufacturing equipment commissioning checklist should start before the purchase order and continue through site acceptance, process qualification, and demonstrated production rate. This guide organizes the work into seven practical control gates: Define, Source, FAT, Install, SAT, Qualify, and Ramp.
Seven-gate equipment launch readiness checklist
Gate 1 — Define: user requirements and acceptance criteria
Before supplier selection, document the intended process, part families, cycle time, quality limits, equipment interfaces, capacity assumptions, operating conditions, maintenance and safety requirements, and required data capture. Each requirement needs an accountable owner and measurable verification method. Establish which requirements will be checked at FAT, SAT, qualification, and run-at-rate.
Exit evidence: approved user requirements specification (URS), requirements-to-test traceability, preliminary layout and utilities, and open-assumptions register.
Gate 2 — Source: technical vendor evaluation
A purchase price does not by itself prove technical suitability. Compare suppliers against mandatory capabilities and weighted criteria such as process capability, controls architecture, maintainability, lead time, spare parts, documentation, service support, and integration risk. Obtain written clarification of exclusions, testing responsibilities, and performance guarantees. Record final supplier-selection approval separately from completion of individual evaluation criteria.
Exit evidence: completed evaluation, technical clarifications, selected supplier, agreed equipment specification, approved sourcing decision.
Gate 3 — FAT: verify before the machine ships
Conduct factory acceptance testing against preapproved criteria. Verify safety-related functions through the required engineering process; demonstrate operating sequences, faults and recovery, controls and interfaces, measurements, documentation, and agreed test parts or simulated loads. Track test status and results separately: a test can be completed but fail. Maintain a deviation/punch list with owners and evidence of retest.
Exit evidence: signed FAT report, accepted test results, approved open-item disposition, shipment authorization.
Gate 4 — Install: verify site readiness
Confirm foundations, floor loads, material flow, crane/rigging plans, utilities, compressed air, electrical capacity, networking, environmental controls, permits, and installation windows. Coordinate utilities, EHS, maintenance, operations, IT/OT, integrators, and contractors. Review site-specific safety measures and do not energize or operate equipment outside approved procedures.
Exit evidence: site readiness checklist, verified installation and utility connections, updated drawings, authorized energization/commissioning.
Gate 5 — SAT: accept installed equipment
Site acceptance testing verifies the installed machine in its real plant environment. Test utility performance, controls integration, operating and fault-recovery sequences, interlocks, alarms, communication with adjacent machines, and agreed site performance criteria. Reconcile FAT open items and SAT deviations. Avoid treating installation completion as site acceptance.
Exit evidence: accepted SAT results, site integration records, updated as-built documentation, closed or formally accepted deviations.
Gate 6 — Qualify: demonstrate the process
Equipment that operates correctly may still be incapable of producing compliant product. Define the applicable qualification or validation protocol: approved process windows, tooling and workholding, inspection method, material and part traceability, repeatability/capability evidence, operator qualification, and required quality approvals. Sector-specific rules and customer requirements determine the extent of testing.
Exit evidence: approved qualification protocol/report, quality disposition, process controls, training, and production-release authorization as applicable.
Gate 7 — Ramp: demonstrate sustained production
Run-at-rate tests verify throughput and quality over an agreed duration and mix. Measure actual good-parts rate, cycle time, downtime, scrap, staffing, material flow, rework, and maintenance response. Define in advance how changeovers, planned losses, rejected product, and unplanned interruptions will be treated. A short demonstration at nominal cycle time does not establish sustainable output.
Exit evidence: approved run-at-rate report, production-readiness review, known-loss improvement plan, transfer of ownership to operations and maintenance.
What should your commissioning tracker record?
At minimum, track each gate's requirement or task ID, owner, due date, status, measurable acceptance criterion, objective evidence, result, open deviation, risk, approval authority, and closure date. Use the same identifiers across requirements, FAT, SAT, and action tracking to prevent evidence gaps.
Common causes of a delayed equipment launch
- Ambiguous specifications that the supplier and buyer interpret differently
- A FAT booked before representative materials, tooling, or test scripts are ready
- Facility utilities and foundations falling behind equipment delivery
- Mechanical installation complete while controls/IT integration is unfinished
- Accepting test execution as a pass without meeting acceptance criteria
- Declaring success after first parts instead of verified sustained output
Frequently asked questions
Is commissioning the same as SAT?
No. Commissioning covers activities needed to bring equipment into an operational state, such as inspection, energization, configuration, checkout, and troubleshooting. SAT is a defined acceptance demonstration under agreed site criteria; its scope may overlap commissioning activities.
Does equipment qualification happen before or after SAT?
It generally follows successful installation and applicable site acceptance activities, but the exact order, overlap, and approval requirements depend on industry rules, contracts, and the chosen validation strategy.
How do I start without building a tracker from scratch?
Start with the free 35-point FAT checklist for the supplier acceptance stage. For end-to-end launch tracking, ELS Professional is a downloadable Excel-based system with seven-gate readiness, user requirements, weighted vendor evaluation, FAT/SAT tracking, risks, qualification, run-at-rate, and executive status reporting.
