PEKO provides product development engineering services for OEMs that need to close technical gaps, increase design maturity, and prepare complex mechanical, electrical, and electromechanical products for the next stages of NPI.
Our engineers work from the product’s current definition—requirements, CAD, drawings, BOMs, specifications, prototypes, test data, and known issues—to determine what engineering work remains. Depending on product maturity, that may involve requirements development, design analysis, documentation, design refinement, verification planning, or resolution of manufacturability risks.
Because this work is performed within PEKO’s NPI environment, engineering decisions can be reviewed with manufacturing, quality, sourcing, assembly, and test teams before the product advances into physical builds.
What Is Product Development Engineering?
Product development engineering services converts product requirements and design intent into the controlled engineering information needed to analyze, build, test, and manufacture the product.
Depending on the starting point, the work may include defining performance requirements, resolving interfaces and critical parameters, performing engineering analysis, completing the design definition, and developing the drawings, BOMs, technical specifications, test requirements, and other engineering outputs required for the next stage of NPI.
For complex OEM hardware, decisions involving materials, tolerances, GD&T, component selection, structural performance, controls, assembly access, thermal behavior, testability, and interfaces are interdependent. Product development engineering gives those decisions a structured technical basis before the design progresses into controlled physical builds.
Product Development Engineering Services
The engineering scope depends on design maturity, product complexity, and the technical issues that remain unresolved. Within PEKO’s NPI environment, product development engineering services can be focused on requirements, product refinement, analysis, documentation, manufacturability, and verification work needed to advance the design toward controlled prototype and engineering builds.
Product Definition & Design Refinement →
Clarify design intent and translate functional and performance requirements into a more complete product definition. This may include resolving open design questions, defining mechanical and electrical interfaces, establishing critical parameters, refining component selection, improving specification clarity, and completing supporting mechanical or structural design where required.
The level of product refinement depends on the starting point. Some programs require substantial design development, while others need targeted engineering work to achieve design completion in specific subsystems or interfaces before hardware is built.
Engineering Documentation →
Create and update the controlled engineering outputs required to communicate the product definition accurately across engineering and manufacturing.
Deliverables may include CAD models, engineering drawings, BOMs, schematics, technical specifications, interface definitions, and configuration documentation. Drawings can incorporate appropriate GD&T, datum structures, tolerance requirements, materials, finishes, and other information required to manufacture and inspect the hardware.
Engineering Analysis & Design Review
Evaluate the design against functional, structural, thermal, dimensional, reliability, and manufacturing requirements before physical-build decisions become more costly to change.
Depending on the product and identified risks, design analysis may include tolerance analysis, stack-up studies, FEA, thermal analysis, FMEA, reliability evaluation, life testing, and other engineering methods appropriate to the program.
Formal or cross-functional design reviews can bring those results together with requirements, interface definitions, test information, and manufacturing input. The objective is to identify technical issues, document engineering decisions, and perform an appropriate risk assessment before the design advances.
Design for Manufacturing Considerations →
PEKO applies manufacturing-backed engineering while design changes are still practical. Machining, fabrication, assembly, sourcing, inspection, tooling, and test requirements can be reviewed against the developing product definition to identify features that may create unnecessary manufacturing risk.
This production-focused engineering may address tolerances, material selection, component availability, assembly access, joining methods, inspection access, testability, tooling requirements, or other design decisions that affect downstream builds.
Verification & Test Planning →
Define how critical performance requirements and product requirements will be evaluated as the design develops. This may include verification methods, acceptance criteria, measurable outputs, test conditions, instrumentation requirements, and other test planning needed to support engineering decisions and subsequent builds.
How PEKO Advances a Developing Design
PEKO does not apply the same development sequence to every product. The engineering effort is organized around what has already been completed, what remains uncertain, and what must be resolved before the next build phase.
1. Establish the Current Design Maturity
PEKO reviews available requirements, CAD models, drawings, BOMs, specifications, prototypes, test results, known issues, and program objectives to establish the current design maturity and identify unresolved technical risks.
2. Resolve Technical Gaps
Open issues are addressed using the appropriate combination of requirements development, design refinement, design analysis, engineering documentation, and cross-functional technical review.
3. Confirm the Design Against Requirements
Analysis, design reviews, engineering builds, and testing can be used to evaluate the design against its functional and performance requirements and determine whether additional changes are needed before the configuration advances.
4. Establish the Technical Baseline
As engineering decisions are resolved, drawings, BOMs, technical specifications, test requirements, and other controlled documents are brought into alignment with the approved design. This technical baseline establishes the product definition that subsequent prototype, verification, and NPI activities can build from.
Typical NPI Engineering Deliverables
The exact outputs depend on the condition of the product and the scope of the engineering work, but may include:
- Functional requirements, performance requirements, and critical parameters
- Refined mechanical, electrical, controls, or electromechanical designs
- CAD models and released engineering drawings
- Structured BOMs and component specifications
- Interface definitions, GD&T, and tolerance requirements
- Tolerance analysis, FEA, thermal analysis, or other applicable engineering analysis
- FMEA, documented technical risks, and risk assessment outputs where required
- DFM/DFA findings and manufacturing recommendations
- Design-review findings and documented engineering decisions
- Verification requirements, test methods, and acceptance criteria
- Updated technical and configuration documentation
These engineering outputs provide the controlled product definition needed to support prototype development, verification activities, production-readiness review, and subsequent NPI builds.
Manufacturing-Backed Product Development Engineering
PEKO’s product engineering services are performed within the same environment used to source components, machine parts, fabricate structures, assemble systems, inspect hardware, and execute test requirements.
That connection allows manufacturing input to reach the engineering team while the design can still be changed. DFM/DFA, component availability, tolerance capability, assembly sequence, inspection access, tooling, testability, and other production considerations can be evaluated during product refinement rather than deferred until manufacturing transfer.
As the product advances into prototype and engineering builds, physical hardware provides another source of engineering data. Findings can be incorporated into the product definition while retaining the requirements, analyses, design decisions, and technical history already established within the NPI program.
Support for Complex OEM Products
PEKO supports NPI product development for technically complex OEM products intended for repeatable manufacturing.
Programs may include complex machinery, automated equipment, medical devices, energy systems, semiconductor equipment, defense products, or electromechanical assemblies involving structures, motion, controls, electrical systems, thermal requirements, precision components, or integrated test.
PEKO is best aligned with programs that have defined technical and commercial objectives and require additional engineering depth to increase product maturity before controlled builds and downstream manufacturing.
Product Development Engineering Within a Broader NPI Program
PEKO provides new product development services as part of broader NPI programs intended to progress into physical builds and repeatable manufacturing.
Engineering work remains connected to the manufacturing organization that can support prototype development, pilot production, manufacturing scale-up, and subsequent contract manufacturing as the product matures.
Product Development Engineering FAQs
- Does our product need to be fully designed before PEKO can become involved?
- No. PEKO can support different levels of design maturity, provided the program has defined technical objectives and a credible path to repeatable manufacturing. The starting package may range from requirements, preliminary CAD, and subsystem designs to a substantially complete technical package or functioning hardware. PEKO first establishes what is complete, what remains unresolved, and what engineering work is required to advance the design.
- What is the difference between product development engineering and NPI?
- Product development engineering focuses on the product itself, including requirements, design, analysis, and documentation. New product introduction is broader and coordinates the engineering and manufacturing activities needed to prepare the overall program for production launch.
- Can PEKO continue a design developed by another engineering firm?
- Yes. PEKO can review existing requirements, CAD models, drawings, BOMs, specifications, analysis results, prototypes, and test data to establish the current product definition and identify remaining work. Existing engineering outputs can be retained where appropriate rather than recreating completed work.
- How does product development engineering fit into a broader PEKO NPI program?
- PEKO’s new product development services are delivered within a broader NPI program, not as standalone engineering. As the design matures, the work progresses into prototype or engineering builds and then into the appropriate downstream NPI activities.
- Who owns the designs and engineering work developed with PEKO?
- The customer retains ownership of its product intellectual property. Designs, drawings, documentation, and other work product developed collaboratively for the customer become the customer’s property.
