Develop A Manufacturing Test Strategy That Supports Production Success
PEKO provides test engineering services for OEMs manufacturing complex machinery, equipment, assemblies, and electromechanical systems. Our team helps define how products and systems should be verified, what requirements and acceptance criteria must be met, and how testing should support manufacturing, quality, and final acceptance.
Effective test engineering requires both deep product knowledge and a practical understanding of how testing will be executed in manufacturing. PEKO works with customer engineering teams to translate product requirements, core science, and critical performance parameters into manufacturing-ready test strategies, including FAT planning, ATE requirements, product verification, prototype testing, and life-cycle testing.
Test Engineering Services for OEM Programs
PEKO uses product requirements, engineering analysis, and available technical documentation to identify the critical functional and performance parameters for each program. Our team then determines the appropriate test methods, acceptance criteria, equipment, fixtures, software, and verification approach needed to address those requirements within the manufacturing process.
This support is especially valuable when programs involve interconnected mechanical, electrical, controls, motion, fluid, pneumatic, vacuum, subsystem, or system-level requirements.
What PEKO Helps Define
PEKO can help OEMs define:
- Product requirements, specifications, and verification priorities
- Test objectives and measurable acceptance criteria
- Manufacturing test strategies and production-ready test programs
- Subsystem and system-level test sequences
- Functional verification methods and required test procedures
- Required test standards, methods, protocols, documentation, and schedules
- Fixture, tooling, station, software, or equipment needs
- Opportunities for manual, semi-automated, automated, or ATE-supported testing
- Test planning for NPI, production transfer, and contract manufacturing
- Final verification and factory acceptance requirements before shipment
Depending on the program, PEKO’s test engineering services may include electrical testing, I/O checks, continuity checks, Hi-Pot testing, motion verification, torque checks, force measurement, alignment, calibration, leak testing, pressure decay testing, flow testing, controls verification, PLC/HMI testing, sensor validation, test result analysis, troubleshooting, and acceptance reporting.
When required, PEKO can also help define or support the test software, automation logic, custom fixtures, test setups, and documentation needed to perform these checks consistently within the manufacturing process.
Connecting Test Strategy to Manufacturing
PEKO’s test engineering services are tied to manufacturing execution. The goal is not just to define a test plan, but to define a test approach that can be performed consistently within the actual build process, not only in a separate engineering or lab environment.
Testing may be planned for assembly, final integration, factory acceptance, or on-site verification depending on the program.
This is important when OEMs are transferring a product to production, scaling a complex equipment program, preparing for repeat builds, or defining final acceptance expectations before shipment.
Manufacturing Readiness
A manufacturing-ready test approach helps clarify:
- Where testing belongs in the build sequence
- Which checks should happen before final integration
- What results need to be recorded
- What criteria must be met before the build can move forward
- How test expectations should be reflected in production documentation
Cross-Functional Alignment
Test engineering often connects multiple groups involved in the program. PEKO helps align test planning with mechanical engineering, electrical engineering, controls, assembly, quality, manufacturing documentation, and customer acceptance requirements.
This alignment helps reduce ambiguity before production begins and gives the program a clearer path from requirements to verified output.
Where Test Engineering Services Fit in the Manufacturing Program Lifecycle
Test engineering can support different stages of an OEM manufacturing program. The scope depends on the maturity of the product, the complexity of the build, and the level of documentation or acceptance required.
NPI & Production Readiness
During NPI, test engineering helps define how new equipment or assemblies will be verified before release to repeatable production. It can also help identify unclear requirements, missing acceptance criteria, fixture needs, or documentation gaps before they create late-stage delays.
Production Transfer
During production transfer, test engineering helps review how an existing product or system should be tested in a new manufacturing environment. This may include reviewing legacy procedures, confirming acceptance requirements, and aligning test expectations with PEKO’s manufacturing process.
Contract Manufacturing & System Integration
For ongoing contract manufacturing or system integration programs, test engineering helps maintain a consistent verification approach across builds. This supports quality records, final acceptance, and repeatability for complex OEM equipment.
How PEKO Supports the Broader Test Process
PEKO’s test engineering support extends into the specific activities required to plan, perform, document, and repeat testing across an OEM manufacturing program. The services below highlight how we support each stage of the process—from developing test strategies and procedures to executing tests, validating results, analyzing issues, and planning the fixtures, stations, software, or equipment needed for production.
Test Development
At PEKO, test development translates the overall test engineering strategy into actionable plans that align with manufacturing and production goals. This includes defining test plans, procedures, pass/fail criteria, setup requirements, test software needs, and documentation that support efficient, repeatable testing within an OEM program.

FAQs About Test Engineering Services
How is test engineering different from test development?
Test engineering defines the overall test approach used to verify that a product, assembly, machine, or system meets its requirements. Test development turns that approach into the detailed test plans, procedures, criteria, setups, and documentation needed to perform testing repeatably.
For example, test engineering may define that a completed assembly needs torque verification, leak testing, and functional motion checks. Test development then defines the step-by-step procedures, equipment requirements, measurement methods, pass/fail limits, and documentation format used to complete those tests.
How do test engineering services support product testing during manufacturing?
Test engineering helps determine which functions, build characteristics, and performance requirements need to be checked during production. This gives manufacturing and quality teams a defined basis for performing product testing, recording results, and confirming that each build meets required specifications.
How does test engineering support factory acceptance testing?
Test engineering helps establish the acceptance framework for FAT before the completed equipment reaches final review. This includes clarifying customer requirements, defining the verification scope, and aligning the test approach with the criteria that must be met before shipment.
Can PEKO support manual, semi-automated, and automated testing?
Yes. Depending on the program, PEKO can support manual testing, fixture-supported checks, semi-automated stations, automated test equipment, and production test automation as part of a broader manufacturing or acceptance process.
Does PEKO provide standalone testing lab services?
PEKO’s test engineering support is typically provided as part of broader OEM manufacturing, NPI, production transfer, custom machine building, system integration, or contract manufacturing programs. PEKO is not positioned as a standalone third-party testing lab.
