Validation & Test Program Support

Overview

Validation is where engineering assumptions become evidence. A product may be technically sound, but if the validation plan is incomplete, test procedures are unclear, or results are not documented properly, the program can lose time late in development.

WT Engineering supports teams preparing for product validation, lab testing, customer acceptance, certification pre-testing, or release readiness.

The focus is practical: clarify what needs to be tested, connect tests to requirements and risks, prepare usable procedures, and help the team produce evidence that can be reviewed and defended.

What we do

Support may include:

• validation plan development

• test procedure writing

• requirements-to-test traceability

• test readiness reviews

• lab test preparation

• test data review

• deviation and failure tracking

• retest planning

• validation summary reports

• coordination support with labs or internal test teams

• review of pass/fail criteria and test assumptions

• support during issue resolution after failed or marginal tests

Typical questions we help answer

• What needs to be tested before the next milestone?

• Are validation activities clearly linked to product requirements?

• Are the test procedures detailed enough to execute repeatably?

• Are pass/fail criteria clear and defensible?

• What evidence will be needed for customer, lab, or certification review?

• What should be fixed before spending time or money on formal testing?

• How should failures, deviations, or marginal results be documented?

Our approach

We start by understanding the product, intended use, known risks, requirements, and upcoming test or review milestone. From there, we review the existing validation plan, test procedures, requirements, and supporting documentation.

The output is intended to help the engineering team execute. That means identifying missing coverage, unclear assumptions, weak pass/fail criteria, documentation gaps, and technical risks that could affect schedule or test success.

The goal is to help the team enter testing with fewer unknowns and leave testing with evidence that is easier to review, explain, and use.

Why it matters

Validation problems are expensive when discovered during or after testing. Missing requirements, unclear procedures, weak pass/fail criteria, and poor result documentation can trigger retesting, customer friction, or delayed release.

A structured validation review helps reduce uncertainty before test execution. It gives the team a clearer basis for planning, execution, documentation, and follow-up.

Relevant experience

WT Engineering brings experience supporting validation planning, certification testing, test lab coordination, and technical documentation for safety-critical EV, lithium-ion battery, marine, and energy systems. Your resume specifically supports experience developing test plans, resolving nonconformances, coordinating with test labs and certification stakeholders, and performing validation planning for battery and electrified systems.  

Relevant areas include:

• battery system validation planning

• component and vehicle-level validation

• third-party lab coordination

• certification and type approval test planning

• EMC issue investigation during type approval testing

• test report documentation

• requirements-to-test traceability

• failed or marginal test follow-up

Good fit for

This service is a good fit when a team is:

• preparing for design validation, customer testing, or certification pre-testing

• building a validation plan for a battery, BMS, vehicle, vessel, or industrial product

• trying to connect requirements to test evidence

• working with internal or external test labs

• responding to failed, marginal, or unclear test results

• closing documentation gaps before a major milestone

• overloaded and needing short-term validation engineering support

Deliverables may include

• validation plan

• test procedure package

• requirements-to-test matrix

• test readiness checklist

• pass/fail criteria review

• deviation or failure tracking log

• retest plan

• validation summary report

• prioritized action plan before testing
