Engineering Design Assurance · GD&T expertise

Avoid programme delays.
Achieve right-first-time design.

We independently review engineering product designs to reduce costs and prevent manufacturing & quality issues before release.

What Our review delivers

Fewer delays. Lower costs. Reduced failures.

We help optimise the synergy between each Engineering function whilst improving key business metrics, such as:

Time

Fewer late engineering changes, fewer repeat tooling iterations, fewer disputes that stall a programme.

Problems caught at the drawing don't propagate to first article inspection failure.

Cost

Unnecessary/excess costs identified & rectified at source, where it is cheap, efficient, and optimal.

A drawing fix/ design iteration costs a fraction of a tooling change.

Quality

Fewer rejections, non-conformances and first-article failures reaching production.

Ambiguity removed before a supplier or an inspector has to interpret it.

Resource & Support

>77% of employers report difficulty finding qualified engineering candidates.

Senior tolerancing and manufacturability depth is exactly the capability hardest to hire and slowest to replace.

A review gives you that depth on the design in front of you, with no vacancy to fill & no headcount mandate to carry.

Inside the review

One report; every release risk in sequence.

The Engineering Design Review runs your design through every lens that decides release readiness, in the order the engineering runs.

The disciplines are the instruments; release confidence is the end-product.

Below are the six core elements to each review:

GD&T & product definition

Are datums, tolerances and drawing requirements functionally correct and unambiguous?

Can a supplier and an inspector both read them one way only?

Tolerance & stack-up analysis

Will the design assemble and function as intended?

Stack-ups that catch the interference before it appears at assembly, when a fix is at its most expensive.

Design for Manufacture (DFM)

Can it be made economically and consistently?

Process, material and features checked against the intended method, before over-specification inflates every quote.

Design for Assembly (DFA)

Can it be assembled efficiently and reliably?

Part count, accessibility and error-proofing, so the build doesn't invite misassembly and line-time cost.

Inspection & verification

Can every requirement be measured and verified as drawn, before it becomes a failed first article and a stalled acceptance after tooling?

Are the correct tooling, measurement equipment and calibration requirements considered?

Supplier interpretation & cross-standard risk

Whether the drawing reads one way only, wherever it lands.

Ambiguity and cross-standard gaps between ASME and ISO environments are what turn into disputes, inconsistent quotes and rejected first articles.

A tolerance that proves hard to manufacture sends the design back a step, which is exactly the loop a review is meant to close before release.

The Integration between stakeholders

The chainlink between Design, Manufacturing and Quality.

Design create the concept. Manufacturing produce it. Quality verifies against it. We align all three.

Design Engineering

Writes the definition: geometry, datums, tolerances, intent.

Manufacturing Engineering

Produces whats written; pays for ambiguity and/or misapplication.

Quality Engineering

Verifies against what's written; pays for ambiguity, misapplication and misinterpretation.

We help prevent the compounding effects, downstream concerns and engineering disputes that can emanate from front end engineering design and propagate throughout the process until final inspection.

One definition, one interpretation, three functions aligned: lower cost, less time, higher quality, fewer failures.

The point of the review

The technical and commercial concerns our reviews are designed to prevent.

One issue missed at the drawing doesn't stay a drawing issue. It resurfaces downstream and manifests in the forms of delays, costs and disputes, such as:

Typical reasons clients get in touch

Common Problems Our Clients Consult us For:

A supplier or customer has challenged the drawing.

A drawing is open to more than one interpretation

Tolerances are too tight, or datum structure is causing concern

Legacy drawings need assessing against current standards

Drawing ambiguity is driving repeat rejections within Quality

A drawing needs sign-off before production release

An ASME drawing must be made or inspected in an ISO GPS environment

A FAIR has been rejected on drawing grounds

WHY IT GETS EXPENSIVE

The later it's found, the more it costs.

A tolerance written ambiguously at design doesn't announce itself. It travels — and the cost of fixing it climbs at every stage it survives.

Drawing release

Cheapest place to fix ambiguity, and almost never where it's caught.

Supplier RFQ

The supplier prices what's drawn; unclear or over-tight callouts inflate the quote, or get absorbed as margin later.

FAIR

First article is where a verification gap surfaces — after the tooling's committed.

Assembly

Conforming parts that won't assemble means the stack-up was wrong, not the parts.

Customer acceptance

A contested interpretation at acceptance stalls revenue and strains the relationship.

Audit/ in-service

The most expensive place to find a datum problem is a field return or an audit finding.

Every stage it survives multiplies the cost of the fix.

What we assess

We pinpoint where a design will fail before it reaches the shop floor.

GENERAL APPLICATION  

Sub-optimal application and reviewal methods which have the potential to cause internal and external disputes.

DATUM APPLICATION & TOLERANCING STACK-UP ANALYSIS

The datum scheme is the backbone, and often the origin of downstream assembly and inspection non-conformances.

STANDARDS & INTERPRETATION

When a drawing crosses between an ASME design office and an ISO-trained supply chain, that gap is where parts get rejected and disputes start.

VERIFICATION & INSPECTION

A callout can be geometrically correct and still impossible to verify as drawn. Our review flags what can't be feasibly measured before the drawing is released.
