Sustaining Engineering & VAVE Services
Sustaining Engineering & Value Engineering (VAVE) Services.
Product lifecycle support, Value Engineering (VAVE), cost reduction, ECO/ECN management, and component obsolescence mitigation.
Sustaining Engineering & VAVE: Scope & Deliverables
Hardware development does not stop at initial commercial launch. WENS Engineering provides comprehensive sustaining engineering and Value Engineering (VAVE) services to safeguard product margins, fortify supply chain resilience, and continually improve hardware reliability throughout its market lifecycle. We manage Engineering Change Orders (ECO/ECN), resolve factory yield and field failure issues, redesign components for aggressive BOM cost takeout, and qualify alternative suppliers when components face obsolescence. Our sustaining engineering outsourcing supports engineering change management, design-to-cost reviews, BOM cost reduction, and manufacturing problem resolution. VAVE recommendations are evaluated against functional requirements, validation needs, supplier capability, and controlled drawing revisions.
Core Engineering Capabilities:
Problems This Service Solves
- High Bill of Materials (BOM) costs eroding product margins after volume manufacturing commences.
- Critical component obsolescence or single-source supplier disruptions stalling production lines.
- Field warranty returns and mechanical failures requiring rapid root-cause investigation and engineering redesign.
- Drawing packages and CAD revisions drifting out of sync with actual shop-floor tooling changes.
- Internal engineering teams overloaded with sustaining change orders instead of focusing on new product R&D.
Our Technical Process
A clear, phased workflow with verification gates at each step.
Product Audit & VAVE Analysis
Deconstruct current BOM costs, analyze field warranty return logs, and identify high cost parts and obsolescence risks.
Engineering Redesign
Re-engineer geometries for part consolidation, evaluate alternative materials, and optimize fabrication processes for cost takeout.
FEA & Prototype Validation
Verify structural safety, environmental resilience, and functional clearances through simulation and sample validation.
ECO Release & Line Transfer
Issue formal ECO/ECN documentation, release updated GD&T drawing revisions, and coordinate hand-off to production tooling.
Standard Project Deliverables
You receive fully documented, revision controlled engineering assets ready for fabrication or your internal engineering systems.
Frequently Asked Questions
What is sustaining engineering for physical hardware products?
Sustaining engineering encompasses the continuous engineering support, maintenance, and optimization of physical hardware products after they enter commercial production. WENS Engineering handles Engineering Change Orders (ECOs), resolves component obsolescence, investigates field failures, and optimizes manufacturing processes so products remain profitable, reliable, and compliant throughout their lifecycle.
How does Value Engineering / VAVE reduce product manufacturing costs?
Value Engineering (VAVE - Value Analysis and Value Engineering) systematically investigates each component, fastener, and material in a product. By consolidating multiple components into single molded or stamped parts, optimizing geometries for faster machining, reducing material mass, and replacing costly custom parts with standard commercial off the shelf (COTS) alternatives, VAVE typically achieves 15% to 35% BOM cost takeout without sacrificing mechanical strength, cosmetic quality, or regulatory compliance.
How does WENS manage Engineering Change Orders (ECOs) and CAD revision control?
We establish strict revision governance adhering to your engineering documentation standards. When a design modification is required, we author the formal Engineering Change Order (ECO/ECN), update the parametric 3D CAD models, redline and reissue the 2D manufacturing drawings with updated revision blocks, and log all changes in the release register.
What is the process for resolving component obsolescence during active production?
When a mechanical or electronic component is discontinued, WENS Engineering analyzes the original component specifications, sources viable form-fit-function alternates, and redesigns any mating brackets or mounting features. We conduct tolerance stack-up and FEA simulations to ensure the alternate part functions identically, then release the revised drawing package for immediate manufacturing adoption.
What do you need for a VAVE or sustaining engineering proposal?
Share the current BOM and drawings, cost drivers, production volumes, change history, and relevant quality or field data. State the cost, reliability, or availability target so WENS can scope the analysis, design changes, validation plan, and ECO or ECN documentation.
